Öğe Proximalmigration of a lumboperitoneal shunt into the cerebello medullary cisterns(ELSEVIER, 2020) Gezer, Burak.; Karabagli, Hakan.; Koktekir, Ender.; Sahinoglu, Mert.Background: Lumboperitoneal (LP) shunt is a type of treatment commonly used in the surgical treatment of pseudotumor cerebri, comorbid hydrocephalus, cerebrospinal fluid (CSF) fistula. Despite the promising results of the LP shunt blockage of %7 and %14 migration rate of complications have been reported. Migration can be rarely observed in the spinal subarachnoid space or even in the intracranial area. We report a case where the LP shunt migrated upward to the cerebellomedullary cisterns. Case Description: A 37-year-old female patient underwent lumboperitonel shunt surgery for pseudotumor cerebri. After the LP shunt surgery, the patient's complaints of headache and blurred vision disappeared. The patient admitted to polycyclic at the postoperative first month with neck pain and neck sucking sensation. Cerebellomedullar cysterna shunt tip was seen in brain CT. The patient was operated again and the proximal end of the shunt was lowered to Lumbar 1 level under C-Arm Scope device control. Then, we fixed the subcutaneous tissue of the shunt of the LP shunt with the help of a non-resorbable suture and stitches. Conclusions: LP shunt distal migration is more common, such proximal migrations are rarely reported in the literature. LP shunt displacement must be due to defective or insufficient anchoring devices of the LP shunt tube. We think that great care must be taken to fix the LP shunt properly with the help of suture collars with an unresorbable suture at three places to the subcutaneous tissue.Öğe The relationship between vasoactive-inotropic score and mortality in adult patients with traumatic brain injury(TURKISH NEUROSURGICAL SOC, 2019) Kara, Iskender; Sargin, Mehmet; Bayraktar, Yesim Serife; Sahinoglu, Mert; Ildarov, Gurban; Duman, Ipek; Celik, Jale Bengi; Karabaglı, HakanAIM: To assess the feasibility of the vasoactive-inotropic score (VIS) in determining the amount of vasoactive support and its relationship with the mortality rate and characteristics of the patients with traumatic brain injury (TBI). MATERIAL and METHODS: This study was conducted with a retrospective design involving the years 2013-2018 in a university hospital which provides tertiary intensive care service. A total of 102 patients who were admitted in the ICU with the diagnosis of severe TBI, and also were followed by neurosurgery service and who received vasoactive and inotropic support were analyzed concerning VIS value. RESULTS: The median age of the patients was 34 years, and 69.6% of the patients were male. Mortality rate was 43.1%. In the group with mean VIS >= 10, the admission duration in the ICU and hospital were shorter (p<0.0001) whereas mortality rates were higher (81.1% vs 21.5% and p<0.0001). Besides, the number of patients with a VIS score of >= 10, >= 15 and >= 20 were higher in the group of patients who died (p<0.0001). The results of the multivariate analysis such as VIS >= 10 were significant. CONCLUSION: We can conclude that VIS, which is used to determine the amount of vasoactive and inotropic medicines during cardiac surgery and in sepsis patients, may be useful in predicting mortality in TBI patients.Öğe Strabismus in hydrocephalus patients(SPRINGER, 2019) Koktekir, Bengu Ekinci; Koktekir, E.; Ozcan, G.; Karabagli, H.Purpose To evaluate the characteristics and outcomes of strabismus in patients with hydrocephalus. Methods A retrospective chart review of patients with strabismus and hydrocephalus is performed in the Department of Pediatric Ophthalmology between 2012 and 2018. Results Seventeen patients between the ages of 6 months and 13 years met the criteria of strabismus and hydrocephalus. Although all had developmental delay, five patients out of 17 were premature (lower than 36 weeks of gestation). All patients had ventriculoperitoneal shunt placement for congenital hydrocephalus. Three patients had exotropia, whereas 14 had esotropia. Glasses were prescribed to 13 patients: hyperopic correction in 12 and myopic correction in one patient. Surgical correction with bimedial recession was performed in five patients. Four of them achieved successful ocular alignment. Conclusions Children with hydrocephalus most likely have esotropia. Although good ocular alignment is achieved with surgical correction in some patients, some patients may benefit from glasses.Öğe Small cell lung carcinoma metastasis to atypical meningioma: ımportance of perfusion magnetic resonance ımaging graphics in differential diagnosis(ELSEVIER SCIENCE INC, 2019) Danisman, Mehmet Cagri; Koplay, Mustafa; Paksoy, Yahya; Keleşoğlu, Kazım Serhan; Karabağlı, Pınar; Köktekir, EnderWe described the imaging findings of small cell lung carcinoma metastasis to atypical meningioma and the importance of magnetic resonance imaging perfusion graphics at the differential diagnosis. To be able to determine subtypes of meningiomas and differentiate whether they are malignant or benign may provide a preoperative idea to determine prognosis and surgical procedure.Öğe Iliac artery ınjury during lumbar disc hernia surgery(ELSEVIER SCIENCE INC, 2019) Şahinoğlu, Mert; Arun, Oğuzhan; Orhan, Atilla; Nayman, Alaaddin; Çalışır, Akın; Bocu, Yasin; Cebeci, Yasemin; Duman, Ateş; Yılmaz, Hüseyin; Köktekir, Ender; Karabağlı, HakanBACKGROUND: Vascular injury complications during lumbar discectomy are rare but potentially life-threatening. Therefore, an early diagnosis and effective treatment management is required for these complications. CASE DESCRIPTION: A 50-year-old female patient was admitted to our outpatient clinic with severe back and right leg pain. She underwent surgery for right L4-5 extruded disc herniation with general anesthesia. Sudden arterial hemorrhage occurred during discectomy performed with straight disc forceps and was controlled using hemostatic materials, with no significant decrease in blood pressure. However, the patient became hypotensive near the end of the operation. The incision was quickly closed, and she was turned to supine position. Emergency abdominal ultrasound, computed tomography, and computed tomography angiography revealed an injury of the left main iliac artery, which was repaired by endovascular stenting. Laparotomy and Bogota bag were applied because of increased intrabdominal pressure at 3 hours postoperative. In addition, a retroperitoneal catheter was placed into the area of the right retroperitoneal hematoma on the first postoperative day. Tissue plasminogen activator was administered through the catheter. On postoperative day 3, the Bogota bag was removed, and the abdomen was closed. The patient was discharged without neurodeficit on day 27. Her abdominal fascial defect was closed with a synthetic graft after 5 months. CONCLUSIONS: Although lumbar discectomy is one of the most commonly performed neurosurgical procedures, the routine rules of discectomy should not be neglected. Early detection and a multidisciplinary approach can help prevent mortality in the event of vascular injury.Öğe Comparison of glasgow coma scale and full outline of unresponsiveness (four) score: a prospective study(TURKISH NEUROSURGICAL SOC, 2019) Bayraktar, Yesim Serife.; Sahinoglu, Mert.; Cicekci, Faruk.; Kara, Inci.; Karabagli, Hakan.; Duman, Ates.; Celik, Jale Bengi.AIM: To assess reliability by comparing the Full Outline of Unresponsiveness (FOUR) scores and Glasgow Coma Scale (GCS) values assigned by specialists from two different fields to patients in the Anesthesiology and Reanimation and Neurosurgery intensive care units. MATERIAL and METHODS: This study was conducted between March 2017 and June 2017 at Selcuk University Faculty of Medicine, Departments of Anesthesiology and Reanimation and Neurosurgery. Seventy-nine patients aged 18-65 years who were treated for at least 24 hours in the intensive care unit were independently assessed by two raters, an anesthesiologist and a neurosurgeon,using FOUR and GCS. The Kolmogorov-Smirnov normality test was applied for continuous variables, and SPSS 20.0 version software was used for data analyses. RESULTS: There were no significant differences between FOUR scores and GCS values given by the two raters. The mortality rate among patients with low scores on both FOUR and GCS was higher than the hospital mortality rate. CONCLUSION: Considering that FOUR score allows a more detailed neurological evaluation than GCS, and our findings suggest that FOUR score is more useful for patients who are unconscious or dependent on mechanical ventilation.Öğe Cauda equina syndrome in a patient diagnosed with type 1 Gaucher disease: a rare case(SPRINGER, 2019) Sahinoglu, M.; Mutlukan, A.; Koktekir, E.; Karabagli, H.BackgroundGaucher disease is a rare hereditary glycolipid storage disease. One of the rare complications is neurodeficits due to vertebral involvement.Case presentationAn 18-year-old female patient presented to the outpatient clinic with cauda equina syndrome due to sacral involvement of type 1 GD. Bilateral laminectomy via posterior approach without posterior stabilization was performed.ConclusionMaximum excision of the mass avoiding destabilization of the spinal column can provide long-term vertebral stability and improvement in neurodeficits.Öğe Early endoscopic ventricular irrigation for the treatment of neonatal posthemorrhagic hydrocephalus: a feasible treatment option or not? a multicenter study(Turkish Neurosurgical Soc, 2018) Etus, Volkan; Kahilogullari, Gokmen; Karabagli, Hakan; Unlu, AgahanAIM: Neonatal intraventricular hemorrhage (IVH) usually results in posthemorrhagic hydrocephalus (PHH). This multicenter study describes the approach of early neuroendoscopic ventricular irrigation for the treatment of IVH/PHH and compares the results with the cases that have been initially treated only with conventional temporary cerebrospinal fluid (CSF) diversion techniques. MATERIAL and METHODS: The data of 74 neonatal PHH cases, that have been treated at three pediatric neurosurgery centers, were retrospectively analyzed. 23 neonates with PHH underwent early endoscopic ventricular irrigation (Group-A). 29 neonates were initially treated with conventional methods (Group-B). 22 neonates underwent ventriculosubgaleal shunt placement (Group-C). Complications, shunt dependency rates, incidence of multiloculated hydrocephalus and incidence of CSF infection were evaluated and compared retrospectively. RESULTS: Group-A, Group-B and Group-C cases did not differ significantly regarding gestational age and birth weight. In Group-A, 60.8% of the patients required a later shunt insertion, as compared with 93.1% of the cases in Group-B and 77.2% of the cases in Group-C. Group-A patients were also associated with significantly fewer CSF infections as well as significantly lower incidence for multiloculated hydrocephalus development as compared with Group-B and Group-C. CONCLUSION: Early removal of intraventricular blood degradation products and residual hematoma via neuroendoscopic ventricular irrigation is feasible and safe for the treatment of PHH in neonates with IVH. Neuroendoscopic technique seems to offer significantly lower shunt rates and fewer complications such as infection and development of multiloculated hydrocephalus in those cases.Öğe Does shunt selection affect the rate of early shunt complications in neonatal myelomeningocele-associated hydrocephalus? a multi-center study(Turkish Neurosurgical Soc, 2018) Kahilogullari, Gokmen; Etus, Volkan; Morali, Tugba Guler; Karabagli, Hakan; Unlu, AgahanAIM: To evaluate the effect of shunt selection on the rate of shunt revision due to early shunt complications in neonatal myelomeningocele-associated hydrocephalus. MATERIAL and METHODS: The data of 157 neonatal myelomeningocele cases in three pediatric neurosurgery centers (Ankara University, Kocaeli University, Selcuk University) who underwent shunt surgery at the time of myelomeningocele repair between 2000 and 2014 were retrospectively analyzed. Clinical features of the patients, shunt types, and early shunt complications within the first three months were recorded. The patients were classified according to several features of the shunt systems, such as the valve type, valve size/contour and catheter type. RESULTS: Of all patients, 71 (45.2%) underwent early shunt revision surgery due to various complications. Mechanical complications were the most frequent cause of shunt failure, followed by infection. There was no significant difference among the valve types. Also, no significant difference was observed among the catheter types. Only valve contour/size (contoured regular/ultra-small/burr-hole/cylindrical/neonatal) seemed to significantly affect the rate of early complications. The patients with neonatal-design valves or ultrasmall valves had significantly less complications, such as poor wound-healing, wound-dehiscence, cerebrospinal fluid leak or shunt exposure. The infection rate secondary to these complications was found to be lower. CONCLUSION: Myelomeningocele patients with prominent hydrocephalus frequently have a friable skin, due to reduced macrocrania-related subcutaneous tissues. Small-sized (neonatal-design or ultra-small) valves may significantly reduce the early shunt complication rate among this population.Öğe Can hypo/hypernatremic conditions be a factor for na ion channel kinetics: model study(Turkish Neurosurgical Soc, 2018) Ayaz, Murat; Karabagli, Hakan; Yanardag, Sirma BasakAIM: Dysnatremic cases are frequently faced in clinical practice. Its macroscopic effects and consequences are well known, but microscopic effects are not well defined. The aim of this study was to reveal the effects of dysnatremia at the cellular level. MATERIAL and METHODS: By using an action potential simulation, the effects of extracellular sodium (Na) concentration on the Na ion channel kinetics were studied. The experimental sets were chosen to mimic hypo/hypernatremic conditions and, in both cases, the degree of the severity was varied. RESULTS: Hyponatremic situations through modifying the axonal Na+ channels kinetics result in the rundown of the sodium current (INa). The degree of the hyponatremia-dependent effect seen in the Na ion channel is severity dependent, which is more effective in the recovery phase of the ion channel. Hypernatremic conditions, on the other hand, have also affected the Na ion channel activity through modifying the kinetics of the channel. Unlike hyponatremia, the effect seen in hypernatremic conditions was through decreasing the response time of the channel. The degree of the significance of the effect seen on the Na ion channel in the case of the hypernatremia was found to be less destructive compared to the hyponatremic condition. CONCLUSION: The Na channels are susceptible to the changes of the extracellular Na concentrations. Thus, the underestimation of hypo/hypernatremic conditions can put patients in danger and close monitoring of serum Na level might be required.Öğe Subaraknoid kanama sonrası rehabilitasyon(2018) Şahinoğlu, MertGünümüzdeki gelişmeler ile birlikte subaraknoid kanama sonucu mortalite oranları düşmeye başlamış olmasına rağmen morbidite oranları aynı düzeylerde devam etmektedir. Buna bağlı olarak hastalarda sadece fiziksel olarak değil, kognitif ve psikolojik disfonksiyonlar gelişmektedir. Rehabilitasyon ile hastada oluşan bu yetersizlikler düzeltilmeye çalışılır. Genel düşünce rehabilitasyonun tedavi sonrası başlaması yönünde olsa da rehabilitasyona başlayana kadar geçen süreçteki birçok faktör de rehabilitasyonun başarısını etkiler. Bu yüzden subaraknoid kanamanın gerçekleşmesi ile başlayan rehabilitasyon süreci hastada oluşabilecek disfonksiyonları en aza indirerek en kısa zamanda hastanın bağımlılığını azaltmayı amaçlamalıdır. Subaraknoid kanama sonrası bu yönde yapılacak rehabilitasyon çalışmaları ile hastaların hayat kalitesi arttırılmalı ve topluma kazandırılmaları hızla sağlanmalıdırÖğe Intradural Intramedullary Conus Medullaris Metastasis of Colorectal Adenocarcinoma: A Case Report(Ege University Press, 2012) Keskin, Fatih; Kalkan, Erdal; Erdi, Mehmet Fatih; Esen, HasanSpinal cord metastasis is rarely seen. Intramedullary spinal metastasis has been defined between the rates of 0,9 -2,1% in the autopsies performed on the cancerous cases. And also intramedullary spinal metastases are defined at a rate of 8,5% in the cases which have metastasis at central nervous system. The male patient, who was at the age of 62, was admitted to our clinic with the complaints of serious back and left leg pain and weakness at the left leg which had begun 15 days before. Low anterior resection + total mesorectal excision + ileostomy were applied to the patient five years ago due to colorectal adenocarcinoma. The carcinoma was reported as adenocarcinoma grade II. Chemotherapy and radiotherapy were applied after postoperative period. Left SLR was positive and 3/5 monoparesis at left leg was determined in the patients neurological examination. Conus medullaris located tumor was determined in the magnetic resonance imaging of the patient. Intradural intramedullary tumor which was infiltrated to the conus medullaris was totally removed with microneurosurgical technique via Th12-L1-2 total laminectomy. Th11-L3 posterior instrumentation and fusion were added because of expansive laminectomy and L1 corpus involvement of the tumor. The histopathological examination was reported as colorectal adenocarcinoma metastasis. In this manuscript we report a colorectal adenocarcinoma metastasis to the conus medullaris for the first time in the literature.Öğe An Unusual Mechanism of Delayed Intracerebral Hemorrhage After Ventriculoperitoneal Shunting: Case Report(Ege University Press, 2012) Koktekir, Ender; Tatarlı, Necati; Ceylan, Davut; Karabağlı, Hakan; Akdemir, GökhanWe present a case of delayed intracerebral hemorrhage that developed seven years after initial ventriculoperitoneal shunt surgery. A seven-year-old boy was admitted to emergency when he experienced sudden headache and vomiting. Computed tomography (CT) scanning showed an intracerebral hemorrhage around the ventricular catheter that cannot be explained by known predisposing factors such as head trauma, coexisting bleeding disorder, occult vascular malformation, and intratumoral hemorrhage. The presumed mechanism in this case is that the ventricular catheter caused contusion of cerebral tissue because the shunt tube at the neck had stretched during the growing up of the child.Öğe Success of Pure Neuroendoscopic Technique in the Treatment of Sylvian Arachnoid Cysts in Children(SPRINGER, 2012) Karabağlı, Hakan; Etus, VolkanNeuroendoscopic approaches to Sylvian arachnoid cysts (SACs) constitute an alternative treatment option to craniotomy for fenestration and shunting procedures. In this study, the authors discuss their experience on pure neuroendoscopic technique in the treatment of SACs in children. The results of treatment of 20 children (range of age, between 7 months and 17 years) with Galassi type II (n, 5) or III (n, 15) SACs who were subjected to pure neuroendoscopic fenestration procedure were presented. It was possible to perform the cystocisternostomy endoscopically in all children with several stomies. The site of the opening was between the optic nerve and the carotid artery in 19, between the carotid artery and the oculomotor nerve in 17, and below the oculomotor nerve in 7. The stomies were enlarged in all cases using the double balloon. Three of the cases required repetition of the operation and two cases required "cystoperitoneal shunt" implantation. There was one minor complication in a patient who had an asymptomatic postoperative subdural effusion, which resolved spontaneously. Of the 18 cases, in which the neuroendoscopic procedures succeeded, 10 showed a reduction in cyst size. The mean follow-up period was 53 months. Our results suggest that "pure neuroendoscopic" approach can be used safely in the management of SACs in children. We recommend at least two fenestration sites for an effective marsupialization of the cyst within the basal cisterns. In pediatric cases, the use of a small diameter rigid endoscope allows to reach safely the planned target areas.Öğe Third ventricle colloid cyst accompanying Aicardi syndrome: A case report [Aicardi sendromuna eşlik eden üçüncü ventrikül kolloid kisti: Olgu sunumu](Gulhane Askeri Tip Akademisi, 2010) Cengiz Ş.L.; Erdi M.F.; Demir L.S.; Baysefer A.Aicardi syndrome is composed of the triad of chorioretinal lacunae, seizures and callosal agenesis. A 3-year-old girl was admitted with the complaints of abnormal eye movements and seizures. In fundoscopic examination, chorioretinal lacunae were detected in both eyes. A magnetic resonance imaging of the brain revealed agenesis of the corpus callosum and a mass obstructing third ventricule. Histopathological examination of the cystic lesion in the patient treated surgically demonstrated colloid cyst. Although good tolerance to intracranial cysts has been reported in Aicardi syndrome, the present patient with cystic lesion obstructing the third ventricle is herein discussed under the light of literature findings. © Gülhane Askeri Ti{dotless}p Akademisi 2010.Öğe The Analysis of the Factors Affecting Lumbar Spinal Stenosis in Adult Patients(SPRINGER LONDON LTD, 2010) Kaptan, H.; İlhan, M.; Çakıroğlu, K.; Kasımcan, O.; Kılıç, C.Background In this study 67 lumbar spinal stenosis in adult patients operated in our clinic in 3 years are aimed to be analysed in terms of clinical and surgical techniques. Methods Diagnoses were made on the basis of patients' histories and their clinical examinations. Results Average age was 52.16 +/- 8.9 (33-64). 70.1% (47) of patients were females and 29.9% (20) were males. The most frequent neurological symptoms were 71.1% lasque (+) and 56.7% sensory loss. The anterior-posterior diameter was below 11.5 mm in 56.7% of the cases. Partial recovery was observed in the early term of 71.6% the cases. 56.7% of the cases were applied total laminectomy. Conclusion Decompressive laminectomy can be performed safely and effectively in patients of with lumbar stenosis.Öğe Rarely Encountered Spinal Tanycytic Ependymoma and Concominant Syringomyelia(Journal Neurological Sciences, 2010) Karabağlı, Hakan; Karabağlı, Pınar; Hakan, TayfunObjective: To present a rare case of the tanycytic variant of intramedullary ependymoma associated with syringomyelia. Case Report: A 51-year-old-woman developed gradual sensory disturbance and weakness of bilateral hands over ten months prior to admission. Magnetic resonance imaging (MRI) demonstrated an enhancing tumor throughout C-2 to C-4 levels of the spinal cord from and syringomyelia extending from C-1 to C-2 and C-4 to C-5. The tumor was totally resected. Histological findings indicated a diagnosis of tanycytic ependymoma. The tumor was characterized by poor cellularity, markedly elongated spindle shaped cells, which were immunopositive for S-100 protein and glial fibrillary acidic protein. Since a complete resection was performed at surgery, no further treatment was proposed. One year later, MRI imaging demonstrated collapse of the cervical syringomyelia. The patient has no recurrence during a 2-year follow up period. Conclusion: Tanycytic ependymoma may occur frequently in spinal cord, especially in the cervical region. It histologically resembles pilocytic astrocytoma and schwannoma; and so other benign spindle cell tumors of the central nervous system should be takes into account in the differential diagnosis. Tanycytic ependymomas should be managed in the same way as ordinary ependymomas, since there is no current evidence suggesting that these morphologic distinct tumors differ in terms of biological behavior. Intramedullary spinal tumors with associated syrinx are not rare, which may be due to the expanding of tumor along the central canal of the spinal cord. The surgical treatment of primary pathology could improve both the tumor and the secondary syringomyelia.Öğe Preventive Effects of Intraperitoneal Selenium on Cerebral Vasospasm In Experimental Subarachnoid Hemorrhage(Lippincott Williams & Wilkins, 2010) Kocaoğullar, Yalçın; İlik, Kemal; Esen, Hasan; Koç, Osman; Güney, ÖnderVasospasm is an important cause of morbidity and mortality with subarachnoid hemorrhage (SAH). The effect of intraperitoneal administration of selenium, which is an antioxidant on cerebral vasospasm was investigated in an experimental model. By means of intracisternal blood injection model, SAH was induced in 24 rabbits, which were randomly divided into 3 groups (group I = control group, group 2 = SAH alone group, and group 3 = SAH plus selenium group). Basilar artery angiography was performed on day 0 and day 3 as described. Intraperitoneal selenium (0.05 mg/kg) treatment was started after the induction of SAH and administered once a day. Three days later, the animals were killed and the basilar artery was examined histologically for the luminal diameter and thickness of the arterial muscular wall. The mean values for the measurements of angiographic luminal diameter, pathologic luminal area.. Muscular wall thickness derived from the blind observer were analyzed statistically. There was no statistically significant difference in basal angiographic luminal diameter evaluation between groups 1-2-3 (P > 0.005). But in third day angiography; comparison of Group 2 and group 1-3 showed statistically significant differences (P < 0.001). In pathologic investigation; there was statistically significant difference in luminal area and muscular wall thickness of the basilar artery between groups 1, 2, and 3 (P < 0.005). Intraperitoneal selenium treatment was found effective by increasing the angiographic diameter, pathologic luminal area and reducine muscular wall thickness measurements. This is the first study to show that intraperitoneal administration of selenium is effective in preventing vasospasm after SAH in rabbits.Öğe Outcomes of Gamma Knife Treatment for Solid Intracranial Hemangioblastomas(Elsevier Sci Ltd, 2010) Karabağlı, Hakan; Genç, Ali; Karabağlı, Pınar; Abacıoğlu, Ufuk; Şeker, Aşkın; Kılıç, TürkerThe aim of this study was to examine the results of gamma knife radiosurgery for 13 patients with residual/recurrent or newly diagnosed solid hemangioblastomas. The 13 patients had 34 solid hemangioblastomas, and all patients underwent gamma knife radiosurgery. Seven patients had von Hippel-Lindau disease and six had sporadic disease. When individual lesions were considered, the overall mean dose at the tumor periphery was 15.8 Gy (range: 12-25 Gy) and the average maximum tumor dose was 31.6 Gy (range: 24-50 Gy). The mean duration of follow-up with MRI was 50.2 months. At the last follow-up evaluation, growth control was achieved for all tumors (partial remission in three tumors [8.8%] and no change in 31 tumors [91.2%]). No radiation-related complications were encountered. Our findings reinforce the view that gamma knife radiosurgery is effective and safe for the management of solid hemangioblastomas with a diameter less than 3 cm, whether they are sporadic or associated with von Hippel-Lindau disease. The high response rate and lack of any radiation-induced side-effects confirms the suitability of the doses used in the present study.Öğe Travmaya Bağlı Osteoporotik Vertebra Çökme KırıklarınınTedavisinde Kifoplasti Uygulaması: Olgu Sunumu(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2010) Eser, Olcay; Aslan, Adem; Coşar, Murat; Kalkan, Erdal; Albayrak, RamazanThe aim of the kyphoplasty method for the treatment of traumatic osteoporotic vertebral compression fractures in geriatric patients is to improve the patient's quality of life. In this report we present two elderly patients who were suffering of traumatic osteoporotic vertebral compression fractures and underwent successful kyphoplasties. Percutaneous kyphoplasty method for the surgical treatment of these fractures decreases the hospitalization, morbidity and mortality in these patients.
