Venous thrombosis and pulmonary emboli is the primary presentation in most cases of PVAs, hence it is a clinically significant abnormality and a potentially morbid and fatal condition. Also, its other complications such as paradoxical embolization and postthrombotic syndrome have been reported [3] [6] . However, we report a symptomatic case of PVA presenting with local symptoms and chronic pain in popliteal region.
