On this background the inferior gluteal artery myocutaneous flap was introduced and refined at our institution over a number of years, which includes the use of adjunctive mesh. The inferior gluteal nerve innervates gluteus maximus, while the superior and inferior gluteal arteries supply it with blood. inferior gluteal artery. The superior gluteal artery perforator (SGAP) flap can be challenging and in common with all flaps can develop venous and arterial insufficiency. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. In a study by Gabrielli et al., the inferior gluteal artery or one of its branches pierced the sciatic nerve in 22.5% of cases [ 2 ].

Then the artery exits the pelvic cavity via the infrapiriform foramen, and further ramifies within the gluteal region muscles. The superior gluteal artery gives off two terminal branches; superficial and deep. Therefore, the inferior gluteal vessels have excellent caliber proximally. Perineal artery branches intto. Accompanied by the pudendal nerve, it then enters the perineum via the lesser sciatic foramen. Along its course, it supplies muscles of the posterior pelvic region.
