# Giant Popliteal Venous Aneurysm—A Rare Cause of Recurrent Pulmonary Embolism

## TL;DR

A rare giant popliteal vein aneurysm caused life-threatening pulmonary embolism in a young woman and was successfully treated with surgery.

## Contribution

Highlights PVA as a rare but important cause of recurrent pulmonary embolism in young patients without traditional risk factors.

## Key findings

- A 30-year-old female with recurrent pulmonary embolism was found to have a giant popliteal vein aneurysm.
- Surgical repair of the aneurysm successfully prevented further thromboembolic events.
- Emergency thrombolysis stabilized the patient before surgical intervention.

## Abstract

Background: A popliteal vein aneurysm (PVA) is a rare vascular abnormality that can lead to the formation of venous thrombi, resulting in potentially life-threatening pulmonary embolism (PE). Methods: We present the case of a 30-year-old female who presented with recurrent pulmonary embolism complicated by cardiorespiratory arrest. Emergency thrombolysis was initiated, which successfully stabilized the patient. Further diagnostic evaluation, including imaging studies, revealed the presence of a giant popliteal vein aneurysm (60/70 mm) as the underlying cause of recurrent embolism. Results: The patient underwent surgical repair of the popliteal vein aneurysm to prevent further thromboembolic events. The procedure was performed successfully, and the patient recovered favorably. Conclusions: This case underscores the importance of recognizing PVA as a potential cause of recurrent PE, particularly in young patients without typical risk factors.
