Abstract
Background: The indentification of the anatomical characteristics of the superior gluteal artery has an important role to facilitate the surgeons in dissecting the superior gluteal perforator artery flap (SGPAF) as a plastic material. Objectives: locate the origin, path, and size of superior gluteal artery (SGA) and its branches on the formol cadavers remains. Materials and methods: This was a cross-sectional descriptive study on 15 human bodies with intact buttocks marinated in formol, at Department of Anatomy, Can Tho University of Medicine and Pharmacy from September 2013 to September 2014. Results: 100% SGA occurred in the gluteal region at the upper margin of piriformis muscle. The distance from the posterior superior ischial spine (PSIS) to the origin of SGA was: 4.91 ± 0.45 cm. The distance from the projection of the origin of the SGA on the shoreline on the straight line connecting PSIS – greater trochanter (GT) to PSIS in the gluteal was: 1.2 ± 0.32 cm. The distance from the projection of the SGA is on the straight line connecting PSIS - GT to PSIS was: 4.77 ± 0.64 cm. The average length and diameter of SGA is: 0.77 ± 0.2 cm and 2.2 ± 0.2 mm. All SGA are shallow and deep branched. The average length and diameter of a shallow branch of a SGA was: 1.39 ± 0.36 cm and 2.08 ± 0.11 mm. The average length and diameter of the deep branch of SGA was 0.9 ± 0.2 cm and 1.81 ± 0.07 mm. Conclusion: The results of this study show that SGA has abundant blood supply capacity for buttocks, which is an important foundation to ensure fundamental basic of the gluteal region flaps during plastic surgery.
