An Incidental Finding Of A Persistent Sciatic Artery - Case Report And Literature Review

Area of Science:

• Vascular Surgery
• Human Anatomy
• Embryology

Background:

• Persistent sciatic artery is a rare congenital anomaly.
• It results from the failure of fetal sciatic artery regression.
• Associated iliofemoral arterial abnormalities and aneurysm formation are common.

Observation:

• A 59-year-old male presented with acute limb ischemia.
• Incidental finding of a thrombosed persistent sciatic artery aneurysm.
• The condition predisposes patients to limb-threatening complications.

Findings:

• The patient's acute limb ischemia was caused by a thrombosed persistent sciatic artery aneurysm.
• This highlights a critical vascular complication of this rare anomaly.
• Prompt diagnosis and management are essential for limb salvage.

Implications:

• Early recognition of persistent sciatic artery is crucial for preventing severe ischemia.
• This case underscores the importance of considering rare vascular variations in acute limb ischemia.
• Management strategies for thrombosed aneurysms in this context require careful consideration.
