笔者在解剖一具成年男性尸体时,发现其左侧闭孔动脉、腹壁下动脉共干起于髂外动脉。为积累资料及为临床提供参考,现将该变异情况报道如下。解剖标本可见,左侧闭孔动脉没有直接起始于髂内动脉,而与腹壁下动脉共干起自髂外动脉(图1),共干长1.14 cm,外径3.0 mm。腹壁下动脉起始处外径2.96 mm,发出后上行入腹直肌鞘。异常的闭孔动脉起始处外径为2.92 mm,起点至闭膜 When dissecting an adult male corpse, the author found that the left obturator artery and inferior abdominal artery co-operated in the external iliac artery. To accumulate data and provide a reference for the clinic, the variation is reported as follows. The anatomical specimens showed that the left obturator artery did not start directly from the internal iliac artery but co-authored with the inferior abdominal artery from the external iliac artery (Fig. 1), with a total length of 1.14 cm and an external diameter of 3.0 mm. The outer diameter of the inferior abdominal artery at the beginning of 2.96 mm, issued after the uplift into the rectus sheath. Abnormal closed-cell artery at the beginning of the outer diameter of 2.92 mm, the starting point to the closed membrane
