Abstract:
Objective:To investigate the incidence and risk factors of hepatic artery injury during percutaneous transhepatic biliary drainage (PTBD).Methods:From Apr 2002 to Dec 2020, the clinical data of 1 446 patients undergoing PTBD were retrospectively analyzed.Results:Hepatic artery injury occurred in 7 cases, with an incidence of 0.48%. Fluoroscopy guided puncture was used in all cases. In those 7 cases (0.48%) a drainage catheter was failed to put in place after multiple attempts, hepatic artery injury occurred in 1 case; One drainage catheter was inserted in 1 314 cases (90.87%), hepatic artery injury occurred in 5 cases; One hundred and twenty-five cases (8.65%) were implanted with two drainage catheter, and 1 case had hepatic artery injury. Failure to successfully insert the drainage catheter increase the incidence of hepatic artery injury ( OR=0.06,95% CI 0.01-0.71, P=0.026) .There were 1 430 cases (98.89%) with oblique needle tip and 5 cases had hepatic artery injury; There were 16 cases (1.11%) with triangular needle tip and 2 cases had hepatic artery injury. Triangular needle tip increased the incidence of hepatic artery injury( OR=55.57, 95% CI 6.84-451.38, P<0.001). Conclusion:Hepatic artery injury is a rare complication of PTBD.The use of triangular needle and the failure of drainage were the risk factors of hepatic artery injury.
