    A rare sciatic artery aneurysm was found in a patient with buttock pain and successfully removed. Persistent primitive sciatic arteries, though uncommon, can lead to aneurysms requiring surgical intervention.

    Area of Science:

    • Vascular Surgery
    • Embryology
    • Radiology

    Background:

    • The primitive sciatic artery is the primary embryonic source of arterial supply to the lower extremities.
    • Persistence of the sciatic artery is a rare developmental anomaly.
    • Aneurysms can develop in persistent sciatic arteries.

    Observation:

    • A patient presented with sciatic-like pain and a pulsatile mass in the buttock.
    • Angiography revealed a large sciatic artery aneurysm.

    Findings:

    • Surgical resection of the sciatic artery aneurysm was performed successfully.
    • The aneurysm was associated with a persistent primitive sciatic artery.

    Implications:

    • Persistent sciatic arteries are clinically significant due to aneurysm formation.

  • Sciatic artery aneurysms pose risks of rupture and distal embolic events.
  • Surgical resection is the recommended treatment for sciatic artery aneurysms.
