Summary
Persistent sciatic artery (PSA) aneurysm is a rare congenital condition causing limb ischemia. Prompt revascularization is crucial for treating this potentially hazardous vascular malformation.
Area of Science:
- Vascular Surgery
- Congenital Malformations
- Peripheral Artery Disease
Background:
- Persistent sciatic artery (PSA) is a rare congenital anomaly where the sciatic artery fails to regress during embryonic development.
- This condition can lead to serious complications, including aneurysmal formation and limb ischemia.
Observation:
- This report details two cases of patients presenting with persistent sciatic artery aneurysm.
- Both patients experienced limb ischemia as a direct consequence of the PSA aneurysm.
Findings:
- Persistent sciatic artery aneurysm is a potentially hazardous condition that requires prompt recognition and management.
- Surgical revascularization is indicated for the treatment of persistent sciatic artery aneurysm to prevent limb-threatening ischemia.
Implications:
- Physicians managing peripheral artery disease must be aware of this rare anomaly.
- Early diagnosis and intervention, including revascularization, are critical for favorable outcomes in patients with persistent sciatic artery aneurysm.
