From: Analysis of anatomical variations of intrapelvic vessels for advanced pelvic surgery
Inter-relationships among the superior gluteal artery (SGA) and the internal iliac artery and vein. (a) The SGA (red) runs dorsal, on the lateral side of the internal iliac vein (blue). (b) The SGA runs dorsal, on the medial side of the internal iliac vein. (c) Representative photograph of the right side of the pelvic cavity, which shows the pattern described in (b). Photograph was acquired during laparoscopic surgery for a lateral lymph node dissection. Asterisk (*) represents the internal iliac vein. IIA, internal iliac artery IIV, internal iliac vein; L5, 5th lumbar nerve; S1, 1st sacral nerve; S2, 2nd sacral nerve; SGA, superior gluteal artery
