Right portal vein embolization by laparoscopic catheterization of the inferior mesenteric vein

Right portal vein embolization is often performed to prevent liver insufficiency after major hepatic resection. The procedure usually involves direct puncture of the portal vein, which requires hepatic hilum manipulation, and may be associated with liver injury, pneumothorax, and hemoperitoneum. This report describes a technique of laparoscopic insertion of a sheath into the inferior mesenteric vein followed by right portal vein embolization.

右门静脉栓塞术（Right portal vein embolization）常被用于预防大型肝切除术后的肝功能不全。该术式通常需行门静脉直接穿刺，操作过程中需对肝门区进行处置，且可能伴随肝损伤、气胸及腹腔积血等并发症。本报告介绍一种经腹腔镜将鞘管置入肠系膜下静脉，随后实施右门静脉栓塞术的技术方法。
