Acute Ischemia of Lower Limbs Caused by Thrombosis of Persistent Sciatic Artery: Case Report

BACKGROUND: Hypoplasia of the external iliac artery with persistent sciatic artery (PSA) is rare. Patients with this condition seek medical treatment mainly due to the formation of persistent sciatic aneurysm or aneurysm complicated with distal ischemia. CASE PRESENTATION: In the present study, we report a case of a patient with thrombosis of PSA without aneurysm in the left lower limb that underwent endovascular treatment. CONCLUSION: Thrombosis of PSA may be associated with sedentary or other unhealthy lifestyles. Endovascular treatment of sciatic arterial diseases could be performed through the brachial artery approach, especially for those with hypoplasia of bilateral iliofemoral arteries.
