Angioplasty of a persistent sciatic artery: case report

Abstract

Transluminal balloon angioplasty is a good choice for the treatment of lower limb arterial occlusion. Although there are some guidelines addressing its indications, some situations are so unusual that there is no consensus on their management. The presence of a persistent sciatic artery is a rare congenital anomaly of the circulatory system and may be associated with early atheromatous degeneration and occlusion. The authors describe the case of an 81-year-old woman that presented with a history of rest pain, atrophic lesion and no distal pulses. Angiogram depicted a persistent sciatic artery with segmental occlusion and distal disease. The therapeutic option was balloon angioplasty of the occluded segment, with technical and clinical success at mid-term follow-up.

Aneurisma da artéria isquiática persistente: relato de caso de tratamento endovascular

“…4,6,9,[12][13][14][15] Grafts with dacron prostheses and PSA angioplasty have also been described in the literature. 16,17 Monitoring, with no surgical treatment, has been recommended in some cases with claudication. 3,13,18 In incomplete persistent arteries, ligature of the PSA without revascularization has also been described.…”

Complete Absence of Iliac Arteries in the Left Hemipelvis in a Case of Deceased Donor Renal Transplantation

“…Congenital abnormalities of the iliac and femoral vessels are rare findings; the most reported findings include iliofemoral aplasia associated with persistent sciatic artery or atresia with residual cord [ 3 , 9 , 10 ]. The persistent sciatic artery supplies blood to the lower limb bud during embryological development and normally regresses and is replaced by the iliac and femoral vessels.…”
