Abstract

HAPA is a rare disease in clinic, and causes include abdominal trauma, hepatobiliary operation, cholelithiasis, infection of biliary tract and adjacent hepatic artery, atherosclerosis, etc [1]. In recent years, medical causes such as liver operation and liver puncture have increased [2]. If HAPA is ruptured and connected with the biliary system, it may lead to gastrointestinal hemorrhage and poor prognosis. In recent years, with the rapid development of skills of interventional radiology and embolic materials, and advantages such as minimally invasive, accurate effect, fewer complications and repeatability, TAE has been mainly used in the treatment of HAPA [3,4].
