目的:正确认识肝总动脉瓣膜单方面闭塞并探讨其介入治疗肝癌的临床价值。材料与方法:肝总动脉闭塞伴胰动脉弓侧支供养肝脏的患者17例,行肠系膜上动脉或胰十二指肠下动脉造影以了解有无肝总动脉瓣膜状闭塞。结果:12例患者肝总动脉呈瓣膜状闭塞,即腹腔动脉造影时肝总动脉完全闭塞,肠系膜上动脉或胰十二指肠下动脉造影时,肝总动脉“闭塞段”血流通畅,类似静脉瓣状。结论:肝总动脉瓣膜状闭塞与多次介入治疗、肝癌切除+术中放置 PCS 及肿瘤浸润有关。放埋置 PCS 时导管不宜过深以保护肝动脉。
Objective: To correctly understand the unilateral occlusion of hepatic arterial valve and explore its clinical value of interventional treatment of liver cancer. Materials and Methods: Hepatic artery occlusion with hepatic artery of the pancreas was used to support the liver in 17 patients. The superior mesenteric artery or pancreaticoduodenal artery angiography was performed to find out whether hepatic arterial valve occlusion was involved. Results: The common hepatic arteries in 12 patients had valvular obliteration. When the hepatic artery was completely occluded during celiac artery angiography, when the superior mesenteric artery or the inferior pancreaticoduodenal artery was angiographed, the common hepatic artery “occluded segment” had a smooth blood flow. , similar to venous valve. Conclusion: The valvular occlusion of the common hepatic artery is related to multiple interventional therapy, liver cancer resection plus intraoperative placement of PCS and tumor infiltration. The catheter should not be too deep to protect the hepatic artery when burying the PCS.
