Persistent sciatic artery, a rare condition, can cause leg ischemia. A combined treatment of catheter fibrinolysis, artery ligation, and bypass surgery successfully restored blood flow in a patient.

Area of Science:

  • Vascular Surgery
  • Anatomy
  • Ischemia Research

Background:

  • Persistent sciatic artery is a rare congenital anomaly resulting from the failure of the embryonic sciatic artery to regress.
  • It is often associated with abnormalities of the superficial femoral artery, leading to potential vascular complications.
  • This condition can predispose individuals to aneurysmal formation and thromboembolic events.

Observation:

  • A case of a complete persistent sciatic artery is presented.
  • The patient experienced peripheral ischemia due to thromboembolism originating from an aneurysm in the buttock region.
  • The clinical presentation highlighted the severe consequences of this rare anatomical variation.

Findings:

  • A multimodal treatment approach was employed, including catheter-directed fibrinolysis to dissolve the clot.

  • Surgical intervention involved proximal and distal ligation of the persistent sciatic artery to prevent further embolic events.
  • A peripheral bypass procedure was performed to re-establish adequate blood flow to the leg.

    • Implications:

    • This case demonstrates the successful management of a complex vascular anomaly presenting with critical limb ischemia.
    • The combined therapeutic strategy highlights the importance of a tailored approach for persistent sciatic artery complications.
    • Restoration of leg perfusion underscores the efficacy of interventional and surgical techniques in managing rare vascular pathologies.
