Abdominal Arteryel Vasküler Varyasyonlarının Tespitinde Çok Kesitli Bilgisayarlı Tomografi

Amaç: Çok Kesitli Bilgisayarlı Tomografi ile abdominal aorta ve ana dallarında izlenen varyasyonları saptamak, bu varyasyonları sınıflandırmak ve sıklıklarını ortaya koymaktır. Gereç ve Yöntem: Ocak 2010 –Mart 2012 tarihleri arasında intravenöz kontrast madde verilmesini takiben dinamik abdomen BT tetkiki yapılan 19-91 yaşları arasındaki 390 erişkin hastanın verileri cinsiyet ve yaş farkı gözetilmeksizin retrospektif olarak çalışmaya alındı. Geçirilmiş solid organ ya da abdominal ana damarsal anatomiyi etkileyebilecek cerrahi öyküsü olan hastalar çalışmaya dahil edilmedi. Veriler iş istasyonunda değerlendirildi. Abdominal aorta ve dallarında görülen varyasyon sıklıkları incelendi ve her iki cinsiyet arasında varyasyon sıklıkları açısından anlamlı bir farklılık olup olmadığı araştırıldı. Bulgular: Çalışmamızda abdominal aorta ve ana dallarında hepatik arter, gastroduedonal arter, çöliyak arter ve renal arterlerde sıklıkla varyasyon saptandı. Splenik arter ve sol gastrik arterde ise diğer damarsal yapılara göre daha az varyasyon izlendi. Varyasyon sıklıkları açısından cinsiyetlere göre istatistiksel anlamlı farklılık saptanmadı. Sonuç: Hepatik ve renal arterlerde varyasyonlar sık görülmektedir. Bu varyasyonların önceden bilinmesi özellikle karaciğer, böbrek nakilleri ve bu organlara yönelik yapılacak girişimsel radyolojik işlemlerde büyük önem arz etmektedir.

Multislice Computed Tomography in the Detection of Abdominal Arterial Vascular Variations

Objective: To evaluate, classify, and find the frequencies of the variations of the abdominal aorta and its main branches with multi-slice computed tomography. Material and Method: Between January 2010 and March 2012, data of 390 adult patients with contrast-enhanced computed tomography were included in the study retrospectively. The patients who had an intraabdominal solid organ or vascular surgery that affects the normal anatomy were excluded. The data were evaluated at the workstation. The frequencies of the variations of the abdominal aorta and its main branches were examined. The effect of gender on variation frequencies was also investigated. Results: In our study, the most frequent variations were at the hepatic artery, gastroduodenal artery, and renal arteries. The variations of the splenic artery and left gastric arteries were relatively rare. Statistically, a significant difference was not detected between genders in frequencies of variations of the arteries. Conclusion: According to our study, variations of the hepatic artery and renal arteries were frequently seen. Identification of the vascular variation is very important before the transplantation of liver or kidney or interventional procedures.
