Bleeding into the bile duct from a hepatic artery pseudoaneurysm is a rare complication of liver transplantation [1] [2] [3] [4] which can be treated by transcatheter coil embolization. Biliary coil erosion after pseudoaneurysm embolization has been reported only once before, and the treatment in that case consisted of surgical choledochotomy [5]. We present a patient who underwent coil embolization of a bleeding pseudoaneurysm after transplantation, in whom coils were later found to have migrated into the bile duct. Surgery was avoided in this patient by removal of the coils by percutaneous cholangioscopy.
A 72-year old patient was admitted in July 2005 with biliary colic. In 2002 he had undergone liver transplantation because of primary biliary cirrhosis. Arterial reperfusion was achieved by end-to-end arterial anastomosis, and biliary reconstruction by duct-to-duct anastomosis. On day 73 after the transplantation he developed a gastrointestinal bleed caused by rupture of a hepatic artery anastomotic pseudoaneurysm, which was treated by packing with microcoils. The bleeding recurred and angiography showed revascularization of the pseudoaneurysm and a hepatic artery anastomotic stenosis. A balloon-expandable ePTFE-covered coronary stent graft was inserted into the hepatic artery to exclude the pseudoaneurysm from the circulation [1]. The clinical course was then uneventful until the biliary colic developed.
Endoscopic retrograde cholangiopancreatography was unsuccessful. Percutaneous transhepatic cholangioscopy was performed, when the vascular coils were noted to be close to the bile duct, with a biliary stone proximal to the coils ([Figure 1]). After maturation of the percutaneous track, a video bronchoscope (160BF; Olympus, Tokyo, Japan) was inserted into the biliary system. As well as the stone, a clew of metallic wires was observed ([Figure 2]). The stone was removed by electrohydraulic lithotripsy. Because the coils, which had apparently migrated from the pseudoaneurysm into the bile duct, could act as a cause of recurrent stone formation, it was decided to remove them via the percutaneous track, and these were successfully cleared from the bile duct (Video 1). The patient was discharged 2 days after the procedure, and has remained asymptomatic since.
