Öğe The cutoff value for the diameter of the saphenous vein in predicting the presence of venous insufficiency(2018) Durmaz, Mehmet Sedat; Ozbakir, Bora; Cebeci, Hakan; Arslan, Serdar; Durmaz, Funda Gokgoz; Arslan, Fatma Zeynep; Tekin, Ali FuatAim: In this study aimed to investigate the relationship between saphenous vein diameters and reflux and to present their sensitivity and specificity values in predicting venous insufficiency (VI).Material and Methods: This study included 162 symptomatic patients admitted to our radiology clinic with complaints of VI in 317 of their lower extremities (LEs) and 67 asymptomatic healthy volunteers with their 134 LEs having no varicose veins. A total of 451 LEs were evaluated for VI with Doppler ultrasonography (US) in the standing position. Results: The saphenous vein diameters were higher at a statistically significant level in the symptomatic patient group than in the asymptomatic healthy volunteers (p<0.001). They were also higher at a statistically significant level in the LEs with clinically significant reflux (p<0.001). A cutoff value of a 5.35 mm diameter for insufficiency in great saphenous vein (GSV) led to 80.20% sensitivity and 79.20% specificity; a 4.85 mm diameter for insufficiency in small saphenous vein (SSV) led to 82.10% sensitivity and 83.60% specificity. Conclusions: A GSV diameter of > 5.35 mm and a SSV diameter of > 4.85 mm are the best cutoff values, which could be used as an additional parameter, for predicting VI with high sensitivity and specificity.Öğe Over Kan Akımının Değerlendirilmesinde Transabdominal Superb Mikrovasküler Görüntüleme ve Konvansiyonel Doppler Görüntüleme Tekniklerinin Karşılaştırılması(Selçuk Üniversitesi, 2019 Mart) Arslan, Serdar; Durmaz, Mehmet SedatAmaç: Bu çalışmada, transabdominal Superbmikrovasküler görüntüleme (SMG), color Doppler (CD) ve power Doppler (PD) görüntüleme yöntemlerinin sağlıklı gönüllülerde intraovarianvaskülariteyi saptamada etkinliği karşılaştırılmıştır. Gereç ve Yöntem: Çalışmaya yaşları 0 – 34 arasında olan 81 sağlıklı gönüllü (n = 162over) dahil edildi. Tüm katılımcılar transabdominal B-modultrasonografi, CD, PD ve SMG ile ayrı ayrı incelendi. Over hacimleri B-mod ultrasonografi ile ölçüldü, ardından CD, PD, SMG (cSMG) ve monokrom SMG (mSMG) yoluyla over kan akımları değerlendiriledi. Bulgular: SMG, over dokusunda düşük hızlı kan akım sinyallerini saptamada CD ve PD'den daha etkiliydi (p> 0.001). CD, PD, cSMG ve mSMG'deki ortalama ovaryanvaskülerite skoru sırasıyla, 0,5 ± 1, 1,8 ± 1,5, 3,3 ± 1,3 ve 4,3 ± 0,9 idi.Over hacimleri ve sağlıklı gönüllülerin yaş ortalaması azaldıkça, mSMG ve cSMG yöntemleri konvansiyonel Doppler tekniklerine göre overvaskülaritesini daha iyi gösterdi. Sonuç: Transabdominal SMG, overvasküleritesini diğer konvansiyonel Doppler tekniklerine kıyasla daha ayrıntılı göstermektedir. SMG, özellikle çocuk hastalarda overvasküleritesinin değerlendirilmesi için inceleme protokolünün bir parçası olmalıdır.Öğe Shear wave elastography evaluation of testes in patients with varicocele(Lippincott Williams and Wilkins, 2020) Erdoğan, Hasan; Durmaz, Mehmet Sedat; Arslan, Serdar; Gokgoz Durmaz, Funda; Cebeci, Hakan; Ergun, Osman; Soğukpınar Karaağaç, SedaWe aimed to determine histological damage in patients with varicocele by comparing the elasticity of their affected testes with that of their normal contralateral testes as well as normal testes of control subjects without varicocele using shear wave elastography (SWE). In total, 48 patients with varicocele (96 testes) and 52 control subjects (104 testes) were included in this study. Shear wave elastography values were measured in the longitudinal plane using an oval region of interest that covered as much of the testicular contours as possible. Fifty testes with varicocele were classified as group A, 46 normal contralateral testes of the same patients as group B, and 104 normal testes of control subjects as group C. The normal group C testes were randomly chosen from patients who had applied for ultrasonography for any reason and agreed to participate in the study. The testicular volume and SWE values were compared between these 3 groups. The average age of the patients was 28.45 years, and no significant difference in age was found between the 3 groups (P = 0.665). A significant difference in the testicular volume was found between groups A and C (P = 0.014). The SWE values were significantly higher in group A than in groups B and C (P < 0.001). No significant correlation was observed between the testicular volume and SWE values in any of the groups. Our results showed that SWE can be used as an effective technique to assess testicular stiffness in patients with varicocele to predict interstitial fibrosis and the severity of histological damage.Öğe Superb microvascular imaging in the visualization of recanalization in deep vein thrombosis(EDIZIONI MINERVA MEDICA, 2018) Durmaz, Mehmet S.; Ozbakir, Bora; Cebeci, Hakan; Arslan, Serdar; Dagli, Mustafa; Arslan, Fatma Z.; Tekin, Ali F.BACKGROUND: The aim of this study was to evaluate the use of the superb microvascular imaging (SMI) technique in the detection of recanalization in deep vein thrombosis (DVT) and to compare the diagnostic value of SMI with that of conventional Doppler imaging (CDI) techniques. METHODS: The study consisted of 30 patients who were admitted to hospital within the first 72 h of a first episode of acute DVT. In total, 78 venous segments of 38 lower extremities were assessed. In all the segments, the venous lumen was totally occluded, intraluminal vascular signals were not detected by any of four vascular imaging techniques (color Doppler [CD], power Doppler [PD], color SMI [cSMI], and monochrome SMI [mSMI]) on admission. All the patients were treated with a standard treatment protocol (low-molecular weight heparin for a minimum of 5 days, followed by treatment with a vitamin K antagonist). One month after the treatment was initiated, grading systems that allowed a qualitative comparison of recanalized blood flow (BF) were applied to assess the performance of the four vascular imaging techniques in the detection of recanalization in the thrombosed venous segments. The diagnostic performances of the four imaging techniques in the detection of recanalized BF were statistically compared. RESULTS: The diagnostic performance of the imaging techniques in the detection of recanalized BF in the thrombosed venous segments was found as follows: mSMI > cSMI > PD > CD. CONCLUSIONS: SMI is a promising and effective method for evaluating the treatment efficacy and may provide more accurate information than CD and PD on recanalized BF in DVT.Öğe Thoracolumbar intramedullary lipoma without dysraphism causing paraplegia in a pediatric patient(ELSEVIER SCIENCE INC, 2016) Tekin, Ali Fuat; Sivri, Mesut; Arslan, Serdar; Tolu, Ismet[Abstract not Available]
