Bilateral Persistent Sciatic Arteries Complicated with Aneurysmal Dilatation and Thrombotic Occlusion: A Case Report

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.

A Ruptured Metastatic Hepatic Gastrointestinal Stromal Tumor Treated by Angiographic Embolization / 대한소화기학회지

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumor of the gastrointestinal tract and occur most frequently in the stomach. The liver is the most common metastatic site of a GIST, and spontaneous rupture of the hepatic metastasis of a malignant gastric GIST is rare. We report the case of a 70-year-old man who presented with sudden right lower quadrant abdominal pain and was diagnosed with a spontaneously ruptured hepatic metastasis of a malignant gastric GIST. The patient was successfully managed with transcatheter arterial embolization of the hepatic artery.
