Summary

Conservative therapy, including prostaglandin E1 and lifelong anticoagulation, effectively managed a patient with complete occlusion of a persistent sciatic artery (PSA). This approach resolved intermittent claudication symptoms for three years.

Area of Science:

  • Vascular Surgery
  • Vascular Anatomy
  • Medical Case Reports

Background:

  • Persistent sciatic artery (PSA) is a rare congenital anomaly where the sciatic artery persists as the main artery to the lower limb.
  • Complete occlusion of a PSA can lead to critical limb ischemia and intermittent claudication.

Observation:

  • A 54-year-old male presented with symptoms of intermittent claudication in the left limb.
  • Angiography revealed bilateral persistent sciatic arteries, with complete occlusion on the left side.

Findings:

  • The patient underwent a conservative treatment regimen: 20 intravenous courses of prostaglandin E1 over 4 weeks, followed by lifelong oral anticoagulation with phenprocoumon (INR 2.5-3.5).
  • After 3 years of treatment, the patient remained asymptomatic with no recurrence of intermittent claudication or limb ischemia.

Implications:

  • Conservative management, including prostaglandin therapy and anticoagulation, can be a viable and effective treatment option for symptomatic occluded persistent sciatic artery.
  • This case highlights the importance of regular clinical and duplex sonography follow-up (every 3-6 months) for patients undergoing conservative management of PSA occlusion.
