观察了320侧中国成年人闭孔动脉的起源和股环与邻近血管的比邻关系。每侧有一支闭孔动脉的共309例,其中起源于髂内动脉系的254例,起源于髂外动脉系的55例。每侧有两支闭孔动脉的共11例,两动脉均起源于髂内动脉系的二例,两动脉分别起源于髂内动脉系和髂外动脉系的九例。闭孔动脉在髂内动脉系的起源点比较分散,与髂内动脉的分支类型没有什么关系。起源于髂外动脉系的异常闭孔动脉,按侧别计,其出现率为20％;按尸体计,其出现率为33.13％。中国人的异常闭孔动脉的出现率与日本人接近,而低于欧美人。异常闭孔动脉的出现率在左、右侧之间和男、女性之间均无显著差异。分析了异常闭孔动脉的行程及其与股环的位置关系,其中具有临床意义的是闭孔动脉行经股环的内侧、紧贴陷窝韧带的后方下行,出现率占总数的5％,较其他作者所报导的出现率高,值得重视。此外,在42.5％的标本中,有较大的静脉行经股环内侧汇入髂外静脉。
The origin of obturator arteries and the close relationship between the femoral ring and adjacent vessels in 320 Chinese adults were observed. Each side has a closed-cell artery in a total of 309 cases, of which 254 cases originated in the internal iliac artery system, 55 cases originated in the external iliac artery system. There were 11 cases of two closed-hole arteries on each side. Both arteries originated from two cases of internal iliac artery. Nine arteries originated from internal iliac artery and external iliac arteries respectively. Obturator artery in the origin of the Department of internal iliac artery more dispersed, and the type of internal iliac artery has nothing to do with the type. The abnormal obturator artery originated from the external iliac artery system, with an incidence of 20% according to the side, and 33.13% according to the carcass. The abnormal occlusion rate of Chinese people is close to that of Japanese, but lower than that of Europeans and Americans. The incidence of abnormal closed-cell arteries was not significantly different between the left and right sides and between men and women. The relationship between the stroke of the closed obturator artery and the position of the femoral ring was analyzed. The clinical significance of the obturator artery was that it passed the medial side of the femoral ring and posterior to the lacuna ligament, accounting for 5% of the total The high rates of reported by other authors deserve attention. In addition, in 42.5% of the specimens, there is a larger vein passing through the inside of the femoral ring and into the external iliac vein.
