The purpose of this study was to evaluate the efficacy and safety of transfemoral liver biopsy with a Quick‐Core biopsy needle in select living donor liver transplantation (LDLT) recipients. Eight LDLT recipients underwent 9 transfemoral liver biopsy sessions. Six patients had undergone modified right lobe (mRL) LDLT, and 2 patients had undergone dual–left lobe LDLT. The indications for transfemoral liver biopsy were a hepatic vein (HV) at an acute angle to the inferior vena cava (IVC) on the coronal plane and a thin (<10‐mm) liver parenchyma surrounding the HV to be biopsied on enhanced computed tomography. Under fluoroscopic guidance, the right inferior HV in the mRL or the left HV in the right‐sided left lobe with a cranial orientation was negotiated with a 5‐Fr catheter via the common femoral vein. Then, a stiffening cannula was introduced into the HV over a stiff guide wire. Needle passage was then performed with an 18‐ or 19‐gauge Quick‐Core biopsy needle. Technical success was achieved in all sessions without major complications. The median number of needle passages was 4 (range = 2‐6). The median total length of obtained liver specimens in each session was 44 mm (range = 24‐75 mm). The median number of portal tracts was 18 (range = 10‐29), and the obtained liver specimens were adequate for histological diagnosis in all sessions. In conclusion, transfemoral liver biopsy with a Quick‐Core biopsy needle is an effective and safe alternative for obtaining a liver specimen when standard transjugular liver biopsy is not feasible because of an unfavorable HV angle with respect to the IVC and/or a thin liver parenchyma surrounding the HV.
