Summary
Popliteal vein aneurysms are rare but can cause pulmonary embolism. Surgical removal is often recommended due to this risk, though follow-up data is limited.
Area of Science:
- Vascular Surgery
- Medical Diagnostics
Background:
- Popliteal vein aneurysm is an uncommon condition.
- It carries a significant risk of pulmonary embolism.
Purpose of the Study:
- To review the characteristics and management of popliteal vein aneurysms.
- To highlight the association with pulmonary embolism.
Main Methods:
- Systematic literature search was conducted.
- Data on 105 identified cases were analyzed.
Main Results:
- Popliteal vein aneurysms showed a slight female and left-sided predominance.
- Pulmonary embolism was the most common serious complication, followed by local symptoms.
- Diagnostic methods evolved from phlebography to duplex ultrasonography.
- Surgical excision with lateral suture was frequently performed; four fatal cases were reported.
Conclusions:
- Popliteal vein aneurysm is a rare condition.
- It should be considered a potential source of pulmonary embolism when no other cause is identified.
