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 Hydatid Cyst of the Posterior Cervical Region(LIPPINCOTT WILLIAMS & WILKINS, 2016) Aybay, Muhsin Nuh; Guler, Ibrahim; Oner, Ozgur; Baktik, Suleyman; Tekin, Ali FuatHydatid cyst is an endemically seen parasitic disease and caused by the larval form of Echinococcus parasites. The disease is mostly seen in liver and lung, and the other involvement is rarely seen. Head and neck involvement is extremely rarely seen and its frequency in the literature is reported as less than 1%. It is usually asymptomatic and the symptoms are related to the compression to the adjacent structures. In this paper, the authors report a patient of hydatid cyst localized in the posterior cervical region.Öğe A rare cause of low back pain: intraspinal synovial cyst containing gas(ELSEVIER SCIENCE INC, 2016) Cebeci, Hakan; Tekin, Ali Fuat; Sivri, Mesut; Kivrak, Ali Sami[Abstract not Available]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]
