RESUMO
Objective To study the role of cover-stent and embolization in the treatment of hepatic artery pseudoaneurysm following liver transplantation.Methods 5 patients with hepatic artery pseudoaneurysm after liver transplantation were treated with cover-stent and embolization between May 2010 and July 2013.The clinical features,imaging findings and complications were reviewed.Results All the 5 patients with hepatic artery pseudoaneurysm were successfully treated.2 patients with intrahepatic pseudoaneurysm received embolization.Of the 3 patients with extrahepatic pseudoaneurysm,2 received cover-stent treatment,and 1 patient received embolization.No complications related to the interventional treatment were encountered.2 patients died from multi-organ failure one month after the interventional treatment.Conclusion Cover-stent and embolization were effective and safe to treat patients with hepatic artery pseudoneurysm following liver transplantations.
RESUMO
Hemobilia é rara e potencialmente fatal. A suspeita de sangramento em trato biliar é maior em casos recentes de trauma hepático ou cirurgia hepatobiliar. Ruptura de pseudoaneurisma de artéria hepática é causa comum de hemobilia. Relatamos 3 casos de hemobilia em indivíduos jovens, acometidos por trauma abdominal, que evoluíram com ruptura de pseudoaneurisma e necessidade de embolização angiográfica de vaso sangrante.
Hemobilia is rare and potentially fatal. Suspect bleeding in the biliary tract is higher in recent cases of liver trauma or hepatobiliary surgery. Rupture of hepatic artery pseudoaneurysm is a common cause of hemobilia. We report 3 cases of hemobilia in young individuals suffering from abdominal trauma, who developed pseudoaneurysm rupture and need for angiographic embolization of bleeding vessel.
