Hepatic or cystic artery pseudoaneurysms following a laparoscopic cholecystectomy: Literature review of aetiopathogenesis,presentation,diagnosis and management

Pseudoaneurysms (psas) of the hepatic and/or cystic artery are a rare complication following a laparoscopic cholecystectomy (lc). generally,psa cases present with haemobilia several weeks following the procedure. transarterial embolisation (tae) is considered the optimal management approach. we report a 70-year-old woman who presented to the sultan qaboos university hospital,muscat,oman,in 2016 with massive hemoperitoneum two weeks after undergoing a lc procedure in another hospital. she was successfully managed using coil tae. an extensive literature review revealed 101 cases of hepatic or cystic artery psas following a lc procedure. haemobilia was the main presentation (85.1%) and the mean time of postoperative presentation was 36 days. the hepatic artery was involved in most cases (88.1%),followed by the cystic artery (7.9%) and a combination of both (4.0%). most cases were managed with tae (72.3%),with a 94.5% success rate. the overall mortality rate was 2.0%. © 2017,sultan qaboos university. all rights reserved.
