Hepatic infarction following selective hepatic artery embolization with microcoils for iatrogenic biliary hemorrhage.

Purpose: The aim of this study was to explore the relation of collateral filling to ischemic or infarcted liver following selective embolization of hepatic artery with microcoils in patients with iatrogenic hemobilia. Methods: We performed retrospective analysis of clinical outcomes and post-embolization angiograms in eight patients (mean age of 66 years) studied over the last 7 years. Hemobilia occurred after percutaneous biliary drainage (n = 5) and percutaneous hepatic biopsy (n = 3).
