Surgical anatomy of the intrapelvic branches of the superior gluteal artery in people of a mesohomorphic somatotype

Abstract

Objectives. To explore data on branching variants of the intrapelvic part of the superior gluteal artery in people of mesomorphic somatotype.Materials and methods. We used 48 male dead bodies (deceased aged 25 to 82) and 30 female dead bodies (deceased aged 28 to 78) whose deaths were the result of accidental causes unrelated to the pelvic organs pathology. The following methods were used to achieve the goal of the study: vascular injection, dissection, statistical processing.Results. The pattern of localization of anastomotic branches of the intrapelvic part of the superior gluteal artery (SGA) in humans of both sexes of mesomorphic somatotype was established for the first time. In men, 59.1% of all anastomotic branches of the SGA are located in the proximal third, 36.4% of anastomoses are in the middle third of this artery, and 4.5% of arterial connections are in the distal third of a. glutea superior. In women, arterial anastomoses branch from the proximal third of the intrapelvic portion of the SGA in 66.6% of cases and in the middle third of this artery in 33.3% of cases. The SGA in men of mesomorphic somatotype anastomoses more frequently than in women with the same type of build. It was found that intrathecal branches and anastomoses of the SGA in men and women of mesomorphic somatotype are predominantly localized along the proximal two thirds of this artery length. New data were obtained on the number of branches originating from a. glutea superior in the pelvic cavity, such as the lateral sacral artery (LSA), iliac-lumbar artery (ILA), obturator artery (OA), middle rectus, lower ureteric artery and rami musculares of the SGA. The SGA was found to be the most frequent source of lateral sacral artery formation in the pelvic cavity in men and women of mesomorphic somatotype.Conclusions. The patterns of branching of the intrathecal part of the SGA are presented. The results obtained are recommended to be used for endovascular occlusion of the SGA to stop bleeding from the damaged distal third of this artery.
