Summary

Interventional procedures like stent grafts and embolization can treat rare persistent sciatic artery (PSA) conditions. Stent-graft exclusion of PSA aneurysms offers a potential surgical alternative.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Anatomical Variants

Background:

  • Persistent sciatic artery (PSA) is a rare congenital anomaly with potential complications.
  • Management strategies for PSA-related pathologies are not well-established.

Observation:

  • This report details three cases of female patients with symptomatic persistent sciatic arteries.
  • Case 1: Aneurysm exclusion with a stent-graft for embolic risk.
  • Case 2: Stent implantation for flow-limiting stenosis causing limb ischemia.
  • Case 3: Failed embolization for pelvic hemorrhage from an incomplete PSA.

Findings:

  • Stent-graft exclusion of a PSA aneurysm was successful and patent at 22 months.
  • Stenting of a stenotic PSA restored pedal perfusion, remaining patent at 18 months.

  • Embolization for hemorrhage from an incomplete PSA was unsuccessful, leading to patient mortality.

    • Implications:

    • Interventional techniques, including stent grafts and embolization, show promise for treating PSA vasculopathies.
    • Stent-graft exclusion may be a viable alternative to surgery for PSA aneurysms, potentially avoiding sciatic nerve injury.
    • Further research is needed to determine the long-term durability of these interventional repairs.
