Aberrancy of the hepatic arterial anatomy is common. Because of its course directly adjacent to the head of the pancreas, a replaced right hepatic artery (RHA) is vulnerable to invasion by peri-pancreatic malignancies. Division of the RHA at the time of pancreaticoduodenectomy, however, may result in hepatic infarction and/or bilioenteric anastomotic complications. We report two cases of patients undergoing preoperative embolization of tumor encased replaced RHAs to allow for sufficient collateralization prior to pancreaticoduodenectomy.
肝动脉解剖结构异常很常见。由于它的位置紧邻胰头部，因此替代右肝动脉（RHA）容易受到胰周恶性肿瘤的侵犯。然而，在胰十二指肠切除术时分离 RHA 可能导致肝梗死和/或胆肠吻合口并发症。我们报告了两例患者，他们在接受胰十二指肠切除术前行肿瘤包裹的替代 RHA 术前栓塞术，以在手术前实现充分的侧支循环。
