Popliteal Venous Aneurysm Associated with Arteriovenou Fistula: A Case Report

Abstract

Venous aneurysm (VA) is a localized dilated lesion without venous extension and meandering, and is a rare disease. VA formed in deep veins has few local symptoms and is often asymptomatic, but popliteal venous aneurysm (PVA) have been diagnosed with pulmonary embolism (PE) due to severe respiratory distress. A 46-year-old man was admitted to our hospital with chest pain and respiratory distress during exertion. He was diagnosed with PE and PVA with arteriovenous fistula (AVF) by contrast CT, and surgery was performed with the start of anticoagulant therapy. The surgery closed the AVF and sewed the PVA. He had a good postoperative course and was discharged 15 days after the operation. Although PVA is rarely associated with AVF, it has been suggested that the presence or absence of AVF should be scrutinized preoperatively.
