A rare persistent sciatic artery caused left foot ischemia in an 18-year-old female. Surgical bypass restored blood flow, resolving complications. This case highlights management of this congenital vascular anomaly.

Area of Science:

  • Vascular Surgery
  • Human Anatomy
  • Congenital Abnormalities

Background:

  • The persistent sciatic artery is a rare congenital anomaly where the embryonic sciatic artery fails to regress.
  • It can lead to various complications, including limb ischemia, due to altered blood flow dynamics.
  • Understanding its anatomy is crucial for diagnosis and treatment.

Observation:

  • An 18-year-old female presented with acute left foot ischemia.
  • Arteriography revealed a completely persistent sciatic artery with a hypoplastic superficial femoral artery.
  • This anatomical variation was identified as the cause of the ischemia.

Findings:

  • Surgical intervention with a left femoro-popliteal bypass using a saphenous vein graft was performed.
  • The procedure successfully restored arterial circulation to the affected limb.

  • Post-operative recovery was uneventful, with no immediate complications.

    • Implications:

    • This case underscores the importance of recognizing persistent sciatic artery in cases of lower limb ischemia, especially in younger patients.
    • Successful surgical management, such as bypass grafting, can effectively treat associated ischemia.
    • Further literature review on clinical, arteriographic, and surgical aspects is warranted.
