髂内动脉分支的研究

A STUDY OF THE BRANCHES OF THE INTERNAL ILIAC ARTERY

髂内动脉分支的状况和类型,在欧洲人方面[1]:有Cloquet、Quain、Schlobig、Krusche、Jaschtschinski、Dwight、Schwalbe-Pfitzner、Braithwaithe[2]、Pick等[3]、Мануйлов[4]等人,在日本人方面:有足立[5,6]、塚本[7]、稗田[8]、河野[9]等人曾进行过研究。

1.The internal iliac artery was investigated in 100 cases.In 23 cases this arterywas divided into anterior and posterior trunks,while in the remaining 77 cases suchtrunks were absent.2.The mode of origin of the superior,inferior gluteal arteries and the internalpudendal artery from the internal iliac artery,may be classified into five principal typesand four subtypes.Among them the second type is most frequent(54 cases),the firstand the third type are next in order,their occurrence are 24 cases and 17 cases respec-tively.The fifth type possesses 2 common trunks and occurs in 4 cases.3.The obturator artery,according to its origin,is divided into three types.Thefirst type,arises from the internal iliac artery,comprises the largest number(81 cases).The second type,arises from the external iliac artery,is next in number(15 cases).Thethird type has two obturator arteries arising from the internal and external arteries(4cases)respectively.4.The iliolumbar artery arises from the internal iliac artery(54 cases),some fromthe superior gluteal artery(12 cases).5.The lateral sacral artery,mostly arises from the superior gluteal artery,occursfrom 1--3 branches.There are 2 branches in 43 cases,one branch in 32 and threebranches in 25 cases.
