[The morphophysiological consequences of experimental ligation of the hypogastric arteries].

Experimental studies on the hypogastric arteries' ligation have pointed out significant changes in the vascular pattern correlated with the time past from the ligation, ligatured vessels, health condition of the patient. They consist in changes in the territory of distribution and the appearance of new anastomosis, that have been grouped in: anastomosis between the central and the peripheral part of the artery or its branches, between the peripheral and the aortic branches, between the uterine artery and subcutaneous abdominal artery, aortico-ovarian and reno-ovarian anastomosis. Based on studies of the vascular pattern in postsurgical state we may conclude;--the ligatured artery gives off more collateral branches than the non-ligatured one;--the vascular network in the ischemic territory is larger in postsurgical than in presurgical state and comes to normal in about 10-20 days;--the ligation of all genital arteries does not result in complete ischemia;--it is impossible to approach all the genital arterial sources, so hysterectomy remains the last choice;--in women with no obstetrical history the ligation does not affect the reproductive potential;--during pregnancy or in postpartum the ligation of the proximal part may stop the haemorrhage, but it results in infertility.
