Persistent sciatic artery (PSA) is a rare congenital anomaly. Management of type 2a PSA with distal embolization can avoid surgery by assessing collateral blood flow for customized treatment.
Area of Science:
- Vascular Surgery
- Congenital Anomalies
- Embryology
Background:
- Persistent sciatic artery (PSA) is a rare congenital anomaly, an embryologic remnant of the internal iliac artery.
- Traditional classifications (e.g., Pillet-Gauffre) categorize PSA by completeness and origin, with type 2a (complete PSA, incomplete superficial femoral artery) being most common.
- Current classifications do not incorporate collateral blood flow, a critical factor in managing limb ischemia.

Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...
