The Surgical Anatomy of the Intrapelvic Anastomoses of the Internal Pudendal Artery

Abstract

Objective: to determine the most common sites of localization and number of the intrapelvic anastomoses of the internal pudendal artery. Material and methods. The material for the research was 141 dead bodies of men (at the age from 27 to 75) and 29 dead bodies of women (at the age from 32 to 82) who had died of causes not related to pelvic pathology. The vascular injection method, preparation method, and statistical processing of the obtained data were used to achieve the aim of the research. Results. It has been found out that in the men and women the intrapelvic anastomoses of the internal pudendal artery are most often formed in the proximal and middle one thirds of the intrapelvic part of the artery, significantly rarely - in its distal one third. There is no linear correlation between the sizes of the diameters of the internal pudendal artery and sizes of the diameters of its intrapelvic anastomoses in the women but there is such a correlation in the men. Conclusion. The performed research has demonstrated that the intrapelvic anastomoses of the internal pudendal artery in the men and women have a definite pattern of their origination.
