Abstract

Histology is of paramount importance in the investigation of hepatic disease but conventional percutaneous liver biopsy is contraindicated when coagulation is significantly impaired. We have used a modified percutaneous approach with plugging of the needle track in 100 patients with vitamin K-resistant prolongation of prothrombin time up to 12 sec above control values or platelet counts as low as 20×109/liter. All were successful, and there were no serious complications. The technique is straightforward and is a feasible alternative to the more complex transvenous approach.
