Abstract
PURPOSE: To describe the technique and outcome of transfemoral transcaval (TFTC) core-needle liver biopsies. MATERIALS AND METHODS: Retrospective chart review was performed on 121 patients who underwent transvenous liver biopsies at a single institution between February 2014 and July 2015, yielding 66 total TFTC liver biopsies for review (65.2% male; mean age, 53.2 y ± 15.0). From August 2014 through July 2015, TFTC biopsies accounted for 64 of 77 (83%) transvenous biopsies. Hepatic tissue was obtained directly through the intrahepatic inferior vena cava from a femoral venous approach. Procedural complications were classified according to Society of Interventional Radiology guidelines. RESULTS: Of the 66 biopsies, technical success was achieved in 64 cases (97.0%). Histopathologic diagnoses were made in 63 cases (95.5%). Fragmented or limited specimens in which a pathologic diagnosis was still made occurred in four cases (6.1%). Complications occurred in two cases (3.0%). Venous pressure measurements were requested in 60 cases, and all were successfully obtained. CONCLUSIONS: TFTC core-needle liver biopsies are feasible and safe as demonstrated in this series of patients.
