Öğe The Association Between Peri-aortic Fat and Long-term Incidence of Major Adverse Cardiovascular Events(Elsevier Science Inc, 2013) Kaya, Zeynettin; Ulucan, Seref; Katlandur, Huseyin; Keser, Ahmet; Tuncez, Abdullah; Alihanoglu, Yusuf Izzettin; Efe, Duran[Abstract Not Availabe]Öğe The association between thoracic periaortic fat and major adverse cardiovascular events(Springer Wien, 2015) Kaya, Zeynettin; Ulucan, Seref; Kayrak, Mehmet; Akyurek, Omer; Katlandur, Huseyin; Keser, Ahmet; Efe, DuranThe study aimed to examine the association between thoracic periaortic fat tissue volume and the long-term incidence of major adverse cardiovascular events. This retrospective cohort study included 433 consecutive patients (372 male and 61 female). Periaortic fat tissue volume was measured via electrocardiogram-gated 64-multidetector computed tomography. The patients were evaluated on an average 3 years of follow-up for major adverse cardiovascular events. The patients were divided into groups according to the presence of major adverse cardiovascular events. Major adverse cardiovascular events were noted in 44 (10.2 %) patients during follow-up. Periaortic fat tissue volume was significantly higher in the major adverse cardiovascular events (+) group (35.4 +/- A 26.1 cm(3) vs. 24.1 +/- A 14.9 cm(3), P = 0.001). The logistic regression model showed that periaortic fat tissue volume (hazard ratio: 1.03; 95 % CI: 1.01-1.05; P = 0.001), the glomerular filtration rate (hazard ratio: 0.98; 95 % CI: 0.96-0.99; P = 0.03), and male gender (hazard ratio: 4.76; 95 % CI: 1.08-20.90; P = 0.04) were independent predictors of major adverse cardiovascular events. Thoracic periaortic fat tissue volume may be considered a useful new parameter for predicting major adverse cardiovascular events.Öğe Clinical and Radiological Results of Microsurgical Posterior Lumbar Interbody Fusion and Decompression without Posterior Instrumentation for Lateral Recess Stenosis(Korean Soc Spine Surgery, 2015) Demirayak, Mehmet; Sisman, Lokman; Turkmen, Faik; Efe, Duran; Pekince, Oguzhan; Goncu, Recep Gani; Sever, CemStudy Design: A single-center, retrospective patient review of clinical and radiological outcomes of microsurgical posterior lumbar interbody fusion and decompression, without posterior instrumentation, for the treatment of lateral recess stenosis. Purpose: This study documented the clinical and radiological results of microsurgical posterior lumbar interbody fusion and decompression of the lateral recess using interbody cages without posterior instrumentation for the treatment of lateral recess stenosis. Overview of Literature: Although microsurgery has some advantages, various complications have been reported following microsurgical decompression, including cage migration, pseudoarthrosis, neurologic deficits, and persistent pain. Methods: A total of 34 patients (13 men, 21 women), with a mean age of 56.65 +/- 9.1 years (range, 40-77 years) confirmed spinal stability, and preoperative radiological findings of lateral recess stenosis, were included in the study. Interbody polyetheretherketone cages and auto grafts were used in all patients. Posterior instrumentation was not used because of limited resection of the posterior lumbar structures. Preoperative and postoperative radiographs, computed tomography scans, and magnetic resonance imaging were assessed and compared to images taken at the final follow-up. Functional recovery was also evaluated according to the Macnab criteria at the final follow-up. Results: The average follow-up time was 35.05 +/- 8.65 months (range, 24-46 months). The clinical results, operative time, intraoperative blood loss, and duration of hospital stay were similar to previously published results; the fusion rate (85.2%) was decreased and the migration rate (5.8%) was increased, compared with prior reports. Conclusions: Although microsurgery has some advantages, migration and pseudoarthrosis remain challenges to achieving adequate lumbar interbody fusion.Öğe Karaciğer tümör ve tümör benzeri lezyonlarında ultrasonografi, bilgisayarlı tomografi ve manyetik rezonans görüntülemenin tanı değeri(Necmettin Erbakan Üniversitesi Meram Tıp Fakültesi, 2002) Efe, Duran; Açıkgözoğlu, SaimBu çalışmada 1999-2001 yıllan arasında Selçuk Üniversitesi Meram Tıp Fakültesi Hastanesinde karaciğer fokal lezyonu olan 57 hasta dahil edildi. Bu hastalara USG, BT, MRG tetkikleri uygulandı. Bu yöntemlerin tanıya katkıları ve birbirlerine üstünlükleri araştırıldı. Tüm olguları dikkate aldığımızda USG de 53 hastadan 40 tanesine( %75,4), BT de 55 hastadan 51 tanesine( %92.7 ) ve MRG de 44 olgudan 42 tanesine ( %97.6) doğru tanı koyduk USG karaciğer lezyonlarını saptamada ve çoğu lezyona patolojik tanı koymada kolay, ucuz ve her zaman uygulanabilen bir tetkiktir. Ayrıca takiplerdede güvenle uygulanabilir yöntemdir. Dolayısı ile karaciğer fokal lezyonlannda ilk uygulanması gereken tetkiktir. BT ve MRG ise özellikle obez ve yoğun intestinal gazlı hastalarda tercih edilmesi gereken yöntemlerdir. Bu tetkikler lezyon adedi ve yayılımını belirlemede, küçük ebatlı patolojileri saptamada ve karakterize etmede avantajları vardır. MRG ek olarak hemanjiom-hepatoma, Abse -metastaz, metastaz-multifokal hepatoma gibi kabaca benign-malign lezyon ayrımında üstün bulunmuştur.
