CLINICAL VALUE OF ANASTOMOSIS BETWEEN MIDDLE RECTAL AND UTERINE ARTERIES IN ENDOVASCULAR INTERVENTIONS

Purpose: to study relation between middle rectal and uterine arteries in norm and with uterine fibroids.Materials and methods: the analysis of angiograms of 63 patients with the uterine fibroids and without pathology (n=29 and n=34 respectively) was performed. Localization of orifices of middle rectal arteries, their diameter, existence anastomosis with uterine arteries are estimated.Results: the right middle rectal artery generally departed at level or earlier than uterine artery (26,3% and 21,1% respectively), and left was more often above the orifice of a uterine artery (42,1%). Diameter of rectal vessels didn’t differ in both groups (р>0,05). Anastomosis between middle rectal arteries and uterine vessels were better developed in the I group (52,4% of upervision).Conclusion: the network of anastomosis between middle rectal arteries and uterine arteries was more developed in I group (patients with uterus myoma), that caused higher risk of inappropriate embolism. Knowing features of orifices relation helps to reduce time of endovascular intervention and lower radiation influence.
