Abstract
PURPOSE: To determine frequency of and assess risk factors for hepatic artery (HA) injury during percutaneous transhepatic biliary drainage (PTBD) and to discuss the technique and report the clinical outcome of embolization for HA injury. MATERIALS AND METHODS: Over a 14-year period (2002-2016), 1,304 PTBD procedures in 920 patients were recorded. The incidence of HA injury was determined, and possible associated risk factors were analyzed. When injury occurred, HA embolization was performed at the site as close to the bleeding point as possible. Clinical outcomes of these patients after embolization were reported. RESULTS: Of 1,304 PTBD procedures, a left-sided approach was used in 722 procedures (55.4%), and intrahepatic duct (IHD) puncture under ultrasound guidance was used in 1,161 procedures (90.1%). The IHD was nondilated in 124 (9.5%) patients. The punctured ductal entry site was peripheral in 1,181 (90.6%) patients. In this series, 8 procedures (0.61%) were complicated by HA injury. IHD dilatation status was the only risk factor (P = .017) for HA injury. Embolization was performed with technical and clinical success in all 8 patients. No recurrent hemobilia, intraabdominal bleeding, or other sequelae of HA injury after embolization was noted during 1 week to 84 months of follow-up. CONCLUSIONS: HA injury is a relatively rare complication of PTBD. IHD dilatation status was the only risk factor for HA injury in this study. When HA injury occurred, embolization therapy was effective in managing this complication.
