Surgical anatomy of intrapelvic anastomoses of superior gluteal artery

Abstract

To determine topographic variants and the number of intrapelvic anastomoses of superior gluteal artery (SGA). There were 186 corpses of males aged 22-82 years and 109 corpses of females aged 32-93 years. All of them died from accidental causes not associated with pelvic organ diseases. Dissection, vascular injection and statistical analysis were used. In males, SGA forms anastomoses with other branches of internal iliac artery in 24.2% of cases on the right and in 21.0% of cases on the left. Similar collaterals in females are observed in 13.8% of cases on the right and in 15.6% of cases on the left. Mean length of intrapelvic anastomoses of a. glutea superior in males is 1.4 cm, mean diameter - 2.1 mm. Mean length of such collaterals is 2.0 cm in females, mean diameter - 2.2 mm. As a rule, anastomoses are observed in proximal and middle thirds of intrapelvic segment of SGA. Distal anastomoses are rare. Linear correlation between the diameters of a. glutea superior and intrapelvic anastomoses was not detected in females but was fixed in males. Intrapelvic anastomoses of SGA are characterized by certain pattern of discharge in men and women.
