A case of isolated iliac artery aneurysm causing deep venous thrombosis

Abstract

Deep vein thrombosis (DVT) is common. However, it is rarely caused by an iliac artery aneurysm. Our patient was a 69-year-old man who initially presented with right leg swelling. He was diagnosed as having thrombophlebitis. Computed tomography scanning revealed a right iliac artery aneurysm and an inferior vena cava (IVC) thrombus ; the findings were confirmed on angiography. After the IVC filter was placed, the right common iliac artery aneurysm was repaired. After surgery, his right leg swelling disappeared. Six months later, no IVC thrombus was seen on CT.
