笔者在解剖1例成年男性标本时,发现其肝右动脉与中结肠动脉共干发自肠系膜上动脉(图1),据《中国人解剖学数值》,此类变异占3.76%,现报道如下。肝右动脉和中结肠动脉共干发自肠系膜上动脉,共干距肠系膜上动脉起始处3.1 cm发出,干长0.9 cm。肝右动脉向上跨过脾静脉进入肝十二指肠韧带内上行,在脾静脉汇入肝门静脉处走行于肝门静脉后方,继而行于胆总管后方,上行至
The author dissected 1 adult male specimens and found that the right hepatic artery and the middle colorectal artery co-stem from the superior mesenteric artery (Figure 1), according to “Chinese anatomical values”, such variations accounted for 3.76%, are reported below . The right hepatic artery and the middle colonic artery were co-stemmed from the superior mesenteric artery. A total of 3.1 cm from the superior mesenteric artery began to emerge, with a dry length of 0.9 cm. The right hepatic artery extends upwardly across the splenic vein into the hepaticoduodenal ligament and travels upstream of the hepatic portal vein at the portal vein of the splenic vein and then posterior to the common bile duct,
