Arterial pseudoaneurysm as a complication of percutaneous transhepatic biliary drainage: treatment by embolization. 1995

We observed a serious arterial hemorrhage as a complication of percutaneous transhepatic biliary drainage (PTBD). The hemorrhage appeared during catheter placement for implantation of an endobiliary stent as a two-step procedure. It was caused by an arterial pseudoaneurysm and could be successfully treated by superselective embolization. Although there was a preexisting cavernous transformation of the portal vein no signs of liver cell necrosis appeared after embolotherapy. Vascular complications of PTBD will be discussed with regard to their frequency, possible etiology, ways to avoid them and their interventional therapy.

D015901	Angiography, Digital Subtraction	A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.	Digital Subtraction Angiography,Subtraction Angiography, Digital
