Endovascular Treatment of Persistent Sciatic Artery Occlusion: Case Report and Literature Review

Endovascular revascularization of an occluded persistent sciatic artery for chronic limb-threatening ischemia in a patient with Coronavirus Disease 2019

“…Mariani et al 15 reviewed case reports on endovascular management of PSA stenosis and occlusion from 1993 to 2020. They found 14 cases: 6 patients had claudication, 5 had chronic limb-threatening ischemia, and 1 had rest pain.…”

“…Six patients underwent angioplasty alone, four had PSA stenting, two cases of acute limb ischemia were treated with thrombolysis and stenting, and one used a covered stent. 15 The mean follow-up for reported cases when available was 5 months. Patency at 6 months for four cases that reported it was 50%.…”

“…One experienced reocclusion of the PSA and one had aneurysmal degeneration postoperatively. 15 The review suggested that endovascular therapy may be a good treatment for short occlusion or stenosis, but long-term outcomes are unclear. Similarly, several individual case reports for treatment of patients with PSA for aneurysmal disease and occlusive disease reported stent thrombosis within a year underlying the thrombogenic nature of PSA.…”
