The purpose of this study was to evaluate congenital anastomoses between hepatic arteries demonstrated on angiography in ten patients and to correlate the anastomosis with types of hepatic arterial anatomy. We evaluated the types of the hepatic arterial anatomy based on Michels' classification for 720 patients and compared the anatomic types between the patients with the anastomoses (ten patients) and without the anastomoses (710 patients). The diameter of the anastomoses ranged from 1.5 to 3.0 mm (mean, 2.4 mm). Five anastomoses were classified as tortuous type and five as straight type. Based on Michels' classification for types of hepatic arterial anatomy, eight (80%) of ten patients with the congenital anastomoses were classified as type III (replaced right hepatic artery from superior mesenteric artery). The remaining two patients were classified as type IV (replaced right hepatic artery from superior mesenteric artery and replaced left hepatic artery from left gastric artery) and type VIIIa (replaced right hepatic artery from superior mesenteric artery and accessory left hepatic artery from left gastric artery). Eight (16%) of 48 patients who were classified as type III have the anastomoses. In conclusion, the congenital anastomoses were observed especially in patients with replaced right hepatic artery from superior mesenteric artery.
本研究的目的是评估10例患者血管造影显示的肝动脉先天性吻合情况，并将吻合情况与肝动脉解剖类型相关联。我们根据Michels分类法对720例患者的肝动脉解剖类型进行了评估，并比较了有吻合情况的患者（10例）和无吻合情况的患者（710例）之间的解剖类型。吻合口直径为1.5至3.0毫米（平均2.4毫米）。5个吻合口分类为迂曲型，5个为直行型。根据Michels肝动脉解剖类型分类法，10例有先天性吻合情况的患者中有8例（80%）被分类为III型（肠系膜上动脉发出替代右肝动脉）。其余2例患者被分类为IV型（肠系膜上动脉发出替代右肝动脉且胃左动脉发出替代左肝动脉）和VIIIa型（肠系膜上动脉发出替代右肝动脉且胃左动脉发出副左肝动脉）。在分类为III型的48例患者中有8例（16%）存在吻合情况。总之，先天性吻合情况尤其在肠系膜上动脉发出替代右肝动脉的患者中观察到。
