Hepatic arterial infusion pumps are increasingly utilized as an option for liver directed therapy in the treatment of metastatic colorectal carcinoma. After skeletonization of the hepatic artery through the ligation of extra-hepatic branches, these pumps are implanted surgically with their tip placed in the common hepatic artery. Subsequently, a nuclear medicine pump study is performed to ensure homogeneous perfusion of the liver and detect any extrahepatic perfusion. We report a peripheral arc between the superior mesenteric artery and celiac axis, which caused misperfusion on the SPECT nuclear medicine scan.
肝动脉灌注泵越来越多地被用作转移性结直肠癌肝靶向治疗的一种选择。在通过结扎肝外分支使肝动脉骨骼化后，这些泵通过手术植入，其尖端置于肝总动脉中。随后，进行核医学泵检查以确保肝脏均匀灌注并检测任何肝外灌注情况。我们报告了一例位于肠系膜上动脉和腹腔干之间的外周弧形结构，它在单光子发射计算机断层显像（SPECT）核医学扫描中导致了灌注异常。
