Percutaneous transhepatic biliary stenting in patients with intradiverticular papillae and biliary strictures caused by ampullary carcinoma: A case report.

Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy is a well-established procedure for the treatment of bile duct strictures. However, the procedure is difficult to perform in patients with intradiverticular papillae or tumor infiltration of the major papilla. Percutaneous transhepatic biliary stenting (PTBS) is commonly used in the management of malignant biliary stricture.

Treatment of post-liver transplant hepatic artery pseudoaneurysm with balloon angioplasty after failed stent graft placement.

Hepatic artery pseudoaneurysm is a rare complication following liver transplantation but can lead to life threatening hemorrhage if not treated effectively and in a timely manner. We describe a hepatic artery pseudoaneurysm that occurred after liver transplantation in a 53-year-old woman. The pseudoaneurysm was initially treated by implantation of a balloon-expandable covered stent-graft, but an endoleak was observed 6 days later.
