Persistent sciatic artery is a rare vascular anomaly where the sciatic artery supplies the lower limb. Optimal management involves early recognition, aneurysm repair, and vascular intervention for ischemia.

Area of Science:

  • Vascular Anatomy
  • Medical Case Reports
  • Surgical Innovation

Background:

  • Persistent sciatic artery is a rare congenital anomaly with limited reported cases.
  • Clinical presentations often involve mass, ischemia, or gluteal pain, with a slight male predominance.
  • This anomaly affects the primary blood supply to the lower limb, with a high incidence of aneurysms.

Purpose of the Study:

  • To review the clinical presentation and management of persistent sciatic artery.
  • To highlight the importance of understanding developmental anatomy for diagnosis and treatment.
  • To discuss optimal strategies for managing aneurysms and ischemic complications.

Main Methods:

  • Review of historical and recent case reports focusing on clinical aspects.

  • Analysis of patient demographics, symptoms, and affected limbs.
  • Evaluation of various treatment modalities for aneurysms and ischemic sequelae.

    • Main Results:

    • Persistent sciatic artery is a rare variant, with most reports being clinically focused.
    • Aneurysms develop in 50% of patients, typically located caudal to the sciatic notch.
    • Aneurysm ablation with vascular reconstruction and arterial bypasses for ischemia yield the best outcomes.

    Conclusions:

    • Optimal management requires prompt diagnosis, understanding of anatomy, and tailored vascular interventions.
    • Exclusion and bypass of aneurysms are crucial, alongside treatment for ischemic complications.
    • Close observation is recommended for asymptomatic individuals with this rare vascular anomaly.
