Interventional Therapy for the Treatment of Severe Hemobilia After Percutaneous Transhepatic Cholangial Drainage: A Case Series

摘要

From May 2003 to May 2010, a total of 9 patients with severe hemobilia after percutaneous transhepatic cholangial drainage (PTCD) were diagnosed using super-selective angiography and cholangiography, and then were treated with interventional procedures. Two patients with hepatic arterio-biliary fistula underwent proximal and distal arterial embolization of the responsible vessel. Six patients with pseudoaneurysm had pseudoaneurysm occlusion with proximal and distal embolization. Another patient with biliary-portal vein fistula received a biliary fully covered stent placement. The effects in these patients were evaluated using superselective angiography immediately after the intervention and at 3- and 6-month follow-up. In all patients, hemobilia was stopped right after the treatment and no sign of recurrence was noted at 3- and 6-month follow-up after the interventional therapy. Our findings demonstrate that interventional therapy is a simple, minimally invasive, and safe approach for treating severe hemobilia in patients receiving PTCD.
