Öğe Calcified intracranial hydatid cyst: case report(2011) Köktekir E.; Erdem Y.; Gökçek C.; Karatay M.; Yilmaz A.; Bayar M.A.; Sümer S.We present a 26-year-old patient who did farming related work had an asymptomatic intracranial hydatid cyst. A calcified intracranial cystic mass was found on radiological investigations and the patient underwent surgery. The mass was totally excised. The histopathology result reported a hydatid cyst. There were no postoperative complications. Calcification is quite rare in cerebral hydatid cyst. The computed tomography and magnetic resonance imaging provide information that is especially useful for preoperative diagnosis. Observing membrane detachment and daughter cysts during these investigations is pathognomonic. The presence of calcification in the cyst wall and intracystic membranes indicated hydatid cyst.Öğe Intracranial Bilateral Subdural Hematoma as a Complication of Lumbar Nucleoplasty(Lippincott Williams and Wilkins, 2015) Ceylan D.; Köktekir E.; Tatarli N.; Yaldiz C.; Yücel M.Nucleoplasty is a percutaneous intradiscal procedure that uses radiofrequencies to reduce intradiscal pressure and the symptoms associated with the contained lumbar disk herniation. Although patients' outcomes and complications with this technique have not been well documented, there are several reported basic complications such as numbness and tingling, but there are also some vital complications such as discitis, bleeding, even anaphylaxis and death. Here we report a case of bilateral intracranial subdural hematoma as a complication of nucleoplasty for the first time in the literature. This complication should be included in the list of potential complications of nucleoplasty and taken into account in the case of patients who present with headache after nucleoplasty. © 2014 Wolters Kluwer Health, Inc.

A silicone-injected fresh cadaveric cow cranium is a suitable alternative to using a cadaveric human brain for gaining familiarity with the frontal cranial nerves and vascular structures for bifrontal and frontolateral approaches. Methods: A silicone-injected cadaveric cow cranium was prepared by irrigating the major vessels, followed by the injection of silicone colored either red or blue. Results: A three-step approach was designed to simulate microneurosurgical dissection along the frontal lobe and for the dissection of cranial nerves and vascular structures. This laboratory training model is useful for trainees to gain experience in the use of an operating microscope and become more familiar with the anterior neural and vascular structures in bifrontal and frontolateral approaches. Conclusion: The aim of this study was to develop an innovative model to create a life-like microneurosurgical training system. This model simulates bifrontal and frontolateral approaches performed on the human brain. © 2015, Ege University Press.

Materials and Methods: We retrospectively evaluated the 83 patients who operated because of lower cervical spine trauma in Ankara Training and Research Hospital Neurosurgery Clinic. All patients demographic data, type of trauma, cause of trauma, time of surgery, preoperative and postoperative neurologic grades were carefully evaluated. Only those who were closely followed up at least for 1 year, were included in the evaluation. The impact of surgical treatment on neurological status was assessed by using Frankel scale. Neurological improvement was assessed as mild, moderate and significant in respect to upgrade in Frankel scale in one step, two step and three or four step, respectively. Results: The number of male patients was 61 (73.5%) and the number of female patients was 22 (26.5%) The mean age was 45.1(±2,4). 49 patients had the other system injuries at the time of trauma. The most common cause of trauma was traffic accident (62,6%) and the most common mechanism was flexion injury (59%). The most common type of injury was dislocation (74,7%) and the C5 was the most frequently affected vertebra due to the trauma. 48 patients had various neurologic deficits at the time of admission (57,8%). Of these 48 patients 33 patients were surgically treated within the first 24 hours (68,75%) whereas 15 patients operated 24 hours later (31,25%). A total of 10 patients showed neurological improvement (12,04%). Although mild and moderate neurologic improvements were seen in patients who received early (<24 hours) or late (>24 hours) surgery, significant improvement was observed in patients who received surgery within 24 hours. The surgical approaches were anterior, posterior and combined in 73, 6 and 4 patients, respectively. Conclusion: Our study results indicate that the early surgical decompression and stabilization should be performed as soon as possible in patients with incomplete spinal cord injury. We also concluded that only anterior approach is an effective method in most patients who have cervical spinal trauma.Öğe Vascular silicone injection of fresh cadaveric cow cranium: Alternative training model for the human brain [Taze İnek kranium kadavrasının vasküler silikon İnjeksiyonu: eğitim modeli olarak İnsan beynine bir alternatif](Ege University Press, 2015) Tatarli N.; Süslü H.T.; Ceylan D.; Şeker A.; Karabağli H.; Köktekir E.; Özdoğan S.Background: Anatomical and physiological variations of the human brain's vascular system can be observed via silicone injection of the arterial and venous systems. As a novel method, the injection of a fresh cadaveric cow cranium with silicone is an alternative to using the human brain for microanatomical studies. Objective: To report on an improved method for the colored silicone injection of a fresh cadaveric cow cranium using a silicone injection technique. Methods: Five fresh cow crania were injected as an alternative to human brains for microanatomical dissection, in which the preparation consisted of the irrigation of the major vessels and the injection of colored silicone. Cannulation of the internal carotid arteries and the internal jugular veins with catheters was performed, and the vasculature was irrigated with water (major arteries and veins). The fixation of the specimen with either formaldehyde or alcohol, and the colored injection of the arteries and veins with red and blue silicone, respectively, was then performed. Results: The silicone injections resulted in the deeper penetration of the colored solutions into the small cerebral vessels and mesenchymal structures of the fresh cadaveric cow crania. Of the five injected specimens, four exhibited successful injections, while one had suboptimal results. Conclusion: Silicone injection of the cadaveric cow brain, based on the anatomical and physiological assessment of the vasculature of the specimen for microanatomical studies, is suggested as an alternative to using human brain specimens. © 2015, Ege University Press.
