Summary
Persistent sciatic artery (PSA) aneurysm can cause limb pain. Endovascular repair using a covered stent successfully excluded the aneurysm and restored blood flow, offering a safer alternative to surgery.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Congenital Vascular Anomalies
Background:
- Persistent sciatic artery (PSA) is a rare congenital vascular anomaly.
- PSA can lead to serious complications such as aneurysm formation and distal embolization.
- Aneurysms in PSA can present with acute limb ischemia or pain.
