하대정맥 혈전증의 진단 : 초음파 및 CT소견을 중심으로 = Inferior Vena Cava Thrombosis : US and CT Evaluation

다국어 초록 (Multilingual Abstract)

Forty five patients with inferior vena cava(IVC) thrombosis were studied with the use of ultrasonography (US) and Computed tomography (CT). Thirty seven cases were caused by tumor extension and the primary neoplasms were hepatocelular Ca, 26 cases, renal cell Ca, (6 cases), Wilms' tumor(1 case), IVC leiomyosarcoma (1 case) and retroperitoneal metastatic tumor (3 cases). Non-tumor thrombus were 8 cases which included 5 cases of Budd-Chiari syndrome and 3 cases of thrombophlebitis. US and CT both were good for the diagnosis of IVC thrombosis. Cranial extension was better demonstrated by US whereas CT yielded better delineation of the lower extension. Even though, differentiation of tumor from non-tumor thrombi by the echogenecity and density of the thrombus was not possible, the findings of adjacent tumor mass, complete obstructive thrombus within dilated lumen with bulging wall, and and nontapered acute margin of thrombus made the possibility of turombus made the possibility of thrombus more likely.
