Title: Abdominal aortic aneurysm with inferior vena cava compression in association with deep venous thrombosis. Author: Moore RD, Rutter ED, Zapko DR, Kolade VO, Ayyoub SM. Journal: Am J Med Sci; 2013 Dec; 346(6):521-2. PubMed ID: 24263082. Abstract: Deep venous thrombosis (DVT) of the lower extremity may be caused by external compression of the inferior vena cava (IVC) by a neighboring mass. A 55-year-old male presented with 8 months of intermittent left lower extremity swelling and signs of chronic venous stasis. Duplex ultrasound showed extensive DVT in the left leg. Subsequent imaging revealed a 4.2 cm infrarenal abdominal aortic aneurysm (AAA) compressing the IVC. In cases of chronic, unilateral DVT, work-up should include imaging for an anatomic cause. AAA is a rare cause of IVC compression with DVT, and is most commonly related to inflammatory AAAs. Previously reported cases of IVC compression by non-inflammatory AAAs have been secondary to large aneurysms (greater than 6 cm). This case illustrates that smaller AAAs lacking hemodynamically significant IVC obstruction may be found in association with DVT.[Abstract] [Full Text] [Related] [New Search]
