The purpose of this study was to investigate the safety and effectiveness of the transfemoral transcaval (TFTC) liver biopsy technique in patients with hepatic masses with relative contraindications to percutaneous biopsy and/or mass location abutting the inferior vena cava. The medical records of 16 patients (56% men; age range, 21–88 years) who underwent TFTC biopsy of hepatic masses (ranging in diameter from 2.1 to 13.2 cm) from September 2015 to August 2021 were reviewed. Histopathologic diagnoses were made in 15 of 17 (88%) procedures. Two adverse events were noted: worsened preexisting hemobilia requiring embolization in 1 patient, and a decrease in hematocrit level in another patient, requiring only observation. In conclusion, this report showed that the TFTC technique is a relatively safe and effective method for sampling hepatic masses in select cases.

本研究的目的是研究经股经腔静脉 (TFTC) 肝活检技术在肝肿块患者中的安全性和有效性，这些患者有经皮活检的相对禁忌症和/或毗邻下腔静脉的肿块定位。回顾了 2015 年 9 月至 2021 年 8 月期间 16 名患者（56% 为男性；年龄范围为 21-88 岁）接受肝肿块（直径范围为 2.1 至 13.2 厘米）TFTC 活检的病历。17 例 (88%) 手术中有 15 例进行了组织病理学诊断。注意到两个不良事件：1 名患者的预先存在的胆道出血恶化，需要栓塞，另一名患者的血细胞比容水平下降，仅需要观察。综上所述，
