For more than 20 years, placement of a transjugular intrahepatic portosystemic shunt (TIPS) has been a first-line treatment option for portal hypertension in patients with decompensated cirrhosis. It has been used in the management of complications such as variceal bleeding and refractory ascites. [1][2][3] The most commonly reported complications of TIPS include hepatic encephalopathy (10%-49%), shunt stenosis or occlusion (13%-15% with covered stents and 18%-78% with bare stents), sepsis (2%-10%), and stent migration to the portal vein or the right atrium (8%-20%). 1,4 Biliary complications from TIPS are considered rare, and only a few cases have been described. [5][6][7][8][9][10][11][12] We report an unusual complication: the misplacement of a TIPS into the common hepatic duct (CHD).
CASE REPORTA 59-year-old Hispanic man with hepatitis C cirrhosis and portal hypertension presented to an outside hospital with hematemesis. His initial laboratory results included a total bilirubin (Tb) level of 0.8 mg/dL, a serum creatinine (SCr) level of 0.7 mg/dL, and an international normalized ratio (INR) of 1.2. Upper endoscopy revealed bleeding esophageal varices, which were banded. However, the bleeding continued, and a TIPS was placed. An 80 Â 10-mm metallic stent was deployed, and a portogram at the completion of the procedure noted a well-positioned and patent shunt.However, Doppler ultrasound on the following morning demonstrated minimal flow in the shunt. A followup portogram noted that the TIPS was thrombosed, and a TIPS revision was unsuccessful.The patient became progressively more jaundiced, and endoscopic retrograde cholangiopancreatography (ERCP) showed a biliary obstruction at the level of the proximal CHD. Percutaneous transhepatic cholangiography (PTC) was then performed with the placement of bilateral biliary drainage catheters, and the patient was transferred to our facility for further management.At presentation to our center, the patient had a Tb level of 23.9 mg/dL, a SCr level of 1.2 mg/dL, and an INR of 1.4. A computed tomography scan was suspicious for a malpositioned TIPS in the CHD (Fig. 1), and thromboses of the right, left, and main portal veins were noted. Initial contrast studies through the PTC catheters confirmed obstruction of the right hepatic duct (RHD) and left hepatic duct (LHD) with the TIPS seen at its confluence. Delayed images showed contrast tracking around the lateral edges of the shunt, which filled the common bile duct (CBD) distally (Fig. 2). Malposition of the TIPS causing nearly complete obstruction of the CHD was confirmed. The patient's condition deteriorated (Tb level ¼ 24.1 mg/ dL, SCr level ¼ 1.7 mg/dL, and INR ¼ 2.2), and he was evaluated and listed for liver transplantation with a Model for End-Stage Liver Disease score of 32.
