COMMON ILIAC ARTERIES. 



1013 



The common iliac artery is in most cases of sufficient length to admit 

 the application of a ligature without much apprehension of secondary 

 haemorrhage occurring in consequence of insufficiency in this respect. But

THE BIGHT EXTER- 

 NAL AND INTERNAL 

 ILIAC ARTERIES OF 

 THE MALE. ^ 



The viscera of the 

 pelvis have been re- 

 moved as well as the 

 internal iliac veins. 



1, lower part of the 

 abdominal aorta ; 1', 

 middle sacral artery ; 



2, 2, common iliac ar- 

 teries ; 2', right exter- 

 nal iliac ; 3, lower 

 part of the vena cava 

 inferior ; 4, 4, com- 

 mon iliac veins ; the 

 number on the right 

 points by a line to the 

 right internal iliac 

 artery; 4', right ex- 

 ternal iliac vein ; 5, 

 placed on the ilio- 

 lumbar nervous trunk, 

 points to the posterior 

 division of the internal 

 iliac artery giving off 

 the gluteal; 5', ilio- 

 lumbar artery ; 5", 

 lateral sacral artery 

 with branches passing 

 into the anterior sacral 

 foramina ; 6, placed 

 on the anterior divi- 

 sion of the first sacral 

 nerve, points to the 



sciatic artery coming from the anterior division of the internal iliac ; 7, pudtc artery ; 7', 

 the same artery passing behind the spine of the ischium, and proceeding within the 

 ischium and obturator internus muscle, accompanied by the pudic nerve towards the 

 peringeum ; towards /, inferior hremorrhoidal branches are given off ; 7", superficial 

 perineal artery and nerve; 8, hypogastric artery, with the obliterated remains of the 

 umbilical artery cut short, and 8', superior vesical branches rising from it : 9, obturator 

 artery with the corresponding nerve and vein; 9', the pubic twigs which anastomose 

 with descending twigs of the epigastric artery, and from which, by the enlargement of 

 one of them, the aberrant obturator artery may proceed ; 10, inferior vesical ; 11, middle 

 haemorrhoidal vessels rising in this instance from the pudic ; 12, epigastric artery winding 

 to the inside of +, +, the vas deferens and spermatic cord ; 13, circumflex iliac artery ; 

 14, spermatic artery and vein divided superiorly ; 15, twigs of the ilio-lumbar artery 

 proceeding to anastomose with the circumflex iliac. 



it has been shown (p. 420) to be in some instances very short so short 

 that the operation would be inadmissible. In any case in which the 

 common trunk is thus short, it would probably be more prudent to place 

 a ligature on the external iliac and another on the internal iliac, at the 

 origin of each, than to tie the common iliac artery, or the external iliac 

 alone near its commencement. 



The surgeon has it in his power to judge of the length of the artery during
