    Pulmonary emboli can originate from popliteal vein aneurysms, which are rare developmental venous anomalies. Surgical intervention, specifically excision with venous bypass, is recommended over aneurysm repair due to lower complication rates.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Imaging
    • Venous Thromboembolism

    Background:

    • Popliteal vein aneurysms are rare, typically developmental venous anomalies.
    • They are usually asymptomatic, except for the risk of embolic events.
    • Previous case reports are limited, highlighting the rarity of this condition.

    Observation:

    • A case of pulmonary embolus secondary to a popliteal vein aneurysm is presented.
    • Physical examination and noninvasive studies were ineffective in diagnosing the aneurysm.
    • Contrast venography was the definitive diagnostic modality.

    Findings:

    • Popliteal vein aneurysms are a significant, though uncommon, source of pulmonary emboli.
    • Surgical management is indicated due to the embolic risk.

  • Aneurysmorrhaphy has a high thrombosis rate, making excision with venous bypass a preferred surgical option.

    • Implications:

    • Early diagnosis and surgical intervention are crucial for patients with popliteal vein aneurysms.
    • Excision with venous bypass offers a more satisfactory outcome compared to aneurysmorrhaphy.
    • This case underscores the importance of considering rare venous anomalies in the differential diagnosis of pulmonary embolism.
