Abstract

Persistent sciatic artery (PSA), a rare congenital vascular anomaly, increases susceptibility to aneurysms and accounts for 40-61% of the cases. Here, we describe a case of PSA in a 70-yearold man with a history of alcoholic liver cirrhosis. Bilateral complete PSAs were detected incidentally on computed tomography angiography during evaluation for spontaneous intramuscular bleeding in the thigh due to cirrhosis-related coagulopathy. Selective angiography of the left PSA revealed aneurysmal dilatation and thrombotic occlusion of the PSA, which was partially removed with aspiration thrombectomy. Intramuscular bleeding was succesfully managed with empirical embolization of the deep femoral artery.

양측 잔류좌골동맥은 드문 선천성 혈관 기형으로 동맥류를 잘 동반하며, 이는 사례의 40~61%에서 발생한다. 본 증례는 알코올성 간경화가 있는 70세 남자에서 발생한 좌골동맥 잔존의 1예이다. 간경화와 관련된 응고 병증으로 인한 대퇴부 출혈을 평가하기 위해 시행한 컴퓨터단층사진 혈관조영술 검사에서 양측 완전 좌골동맥 잔존이 우연히 발견되었다. 환자는 선택적 좌측 잔류좌골동맥 혈관조영술에서 좌측 잔류좌골동맥의 동맥류 및 혈전성 폐색이 있어 흡인 혈전제거술로 혈전 부분 제거를 시행하였으며 심부 대퇴 동맥의 경험적 혈관조영색전술을 통해 대퇴근육 내 출혈을 성공적으로 치료하였다.
