Catheter-Directed Thrombolysis for Persistent Sciatic Artery Presenting with Acute Limb Ischemia

Abstract

Persistent sciatic artery (PSA) is a rare congenital peripheral artery disorder that is usually detected incidentally on computed tomographic examination. PSA can also cause iliac aneurysm and acute thromboembolism, which are potentially associated with rest pain, claudication, and limb-threatening ischemia. Patients with PSA and leg ischemia should be treated with revascularization and appropriate management of PSA aneurysm. The authors often choose emergent bypass surgery or endovascular intervention for aneurysmal rupture and acute lower-extremity arterial occlusion. This report describes an emergency procedure using catheter-based thrombolysis for acute limb ischemia in a patient with PSA.

Significance of collateral circulation in managing persistent sciatic artery: Two case reports

“…However, after managing thromboembolic occlusion, PSAA should be accessed as it can cause recurrent embolization or aneurysmal dilatation ( 8 , 9 ). There have been some reports of successful distal embolization management through the PSA using the contralateral femoral or brachial approach ( 10 ). Recently, stent-graft placement for managing PSAA has garnered popularity, replacing conventional treatment ( 5 ).…”
