Transjugular Liver Biopsy.

Transjugular liver biopsy (TJLB) was first performed in 1970 and has since become a standard procedure in interventional radiology practices. TJLB can be used when a percutaneous liver biopsy is contraindicated, such as patients with ascites, coagulopathy, congenital clotting disorders or for patients undergoing concurrent evaluation for portal hypertension. While TJLB specimens tend to be smaller with less complete portal triads numerous studies have shown the samples to be adequate for diagnosis and staging. This article will review what the interventional radiologist needs to know about TJLB including indications/work-up, technical details, tips and tricks, and complications.
