Abstract
Transvenous (transjugular) liver biopsy consists in taking a liver specimen through a needle introduced into the liver parenchyma from the lumen of a hepatic vein. This procedure was attempted 104 times in 98 patients in whom percutaneous needle liver biopsy was contraindicated because of massive ascites and/or bleeding tendency. A liver specimen was obtained in 100 out of these 104 attempts; the tissue specimens were unfragmented and large enough to allow correct evaluation of liver architecture in 57 biopsies. The procedure was followed by no or only minor complications in all our patients except one who suffered a fatal intraperitoneal hemorrhage in relation to perforation of liver capsule; perforation was due to an excessive front rotation applied to the needle, a maneuver which therefore must be avoided. It is concluded that transvenous liver biopsy is a workable, efficient, and acceptably safe procedure for obtaining liver specimens in patients with massive ascites and/or bleeding tendency.
