Arterial complications of percutaneous transhepatic biliary drainage.
OBJECTIVE
To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).


METHODS
Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.


RESULTS
The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n = 3) or by arteriography (n = 4).


CONCLUSIONS
Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%).
