Transjugular liver biopsy: assessment of safety and efficacy of the Quick-Core biopsy needle

Abstract

We assessed the safety and efficacy of transjugular liver biopsy with the Quick-Core biopsy needle. Fifty consecutive patients with liver failure and contraindications to percutaneous liver biopsy were referred for transjugular liver biopsy. Eighteen (36%) patients had thrombocytopenia (platelet range = 44-92/microL, mean = 66/microL), 31 (62%) patients had elevated prothrombin times (international normalized ratio range = 1.3-3, mean = 1.6), and 19 (38%) patients had ascites. The Cook Quick-Core biopsy needle was used. Average procedure time was 30 min. Transjugular access to the hepatic veins was successful in 49 of 50 cases. A transfemoral approach was used in one patient. Tissue specimens were satisfactory for histologic diagnosis in all cases. Established cirrhosis was present in 37 (74%) patients. The mean number of cores was 2.2 (range = 1-3). The mean number of portal triads per core was 10.4 (range = 6-20). There were no procedure-related complications. Transjugular liver biopsy with the Quick-Core biopsy needle is safe and effective in patients in whom the percutaneous route is contraindicated by coagulopathy or ascites.
