Results of ligation the internal iliac and ovarian arteries in the experiment

Abstract

Objective: to study in an experiment on animals pathomorphological changes in the tissues of the uterus, appendages and blood vessels after ligation of the internal iliac and ovarian arteries.Materials and methods: An experiment was conducted with 6 mature pigs. Group I (n=3) consisted of intact pigs without surgery, group II (n=3) included animals with ligation of the internal iliac and ovarian arteries on both sides. 12 months after the operation, slaughter was performed and the organo-complex of the uterus with appendages and iliac vessels was taken for electron microscopic pathomorphological examination.Results: comparative results of the study of the uterus, appendages found that the normal structure of the mature uterus was preserved, there were no changes in the structure of the fallopian tubes, tissues and vessels of the ovaries. All changes were found in the area of ligation of the ovarian and internal iliac arteries, although the arteries retained their lumen, but were deformed and surrounded by dense fibrous connective tissue. Conclusion: ligation of the ovarian and internal iliac arteries with absorbable suture material causes only local changes. The sufficiency of collateral blood flow is confirmed by the absence of atrophy of the uterus, fallopian tubes and ovaries, as well as organ deformities.
