The Safe Gluteoplasty: Anatomic Landmarks to Predict the Superior and Inferior Gluteal Veins

The increase in demand for gluteal fat grafting seen in recent years in the United States has not been met with an equal gain in knowledge of the perils of this anatomic territory. The purpose of this study was to identify anatomic landmarks that can be readily used by surgeons to identify the takeoff of the superior and inferior gluteal veins. Six fresh cadaveric gluteal specimens were dissected at the University of Louisville anatomy laboratory. A question mark incision was made for exposure, followed by identification of the sciatic nerve in the proximal thigh. This was traced retrograde to the sciatic forearm. The piriformis muscle was identified dividing the foreman into superior and inferior portions, which corresponded to the takeoff of the superior and inferior gluteal vessels, respectively. The distance of the gluteal vessels from the one-third point of a line from the mid-sacrum to the greater trochanter was measured. Our cadaveric dissection series demonstrated that the superior and inferior gluteal veins were on average 3.28 cm (2-5.9 cm) and 1.25 cm (0-3.5 cm) away from the point one third the distance from the mid-sacral border to the greater trochanter. The mid-sacrum and the trochanter of the femur are the anatomic landmarks used to identify the large gluteal vein trunks. Understanding the location and trajectory of these deep gluteal structures with use of readily identifiable landmarks may assist surgeons in avoiding inadvertent injection of fat to these veins during fat grafting.
