Such vessels may entrap nerves of the lumbosacral (LS) plexus against the pelvic sidewalls, producing symptoms not typically encountered in gynecological practice, including sciatica and refractory urinary and\/or anorectal dysfunction. We describe cases of sciatica in which laparoscopy revealed compression of the LS plexus by variant superior gluteal veins (SGVs). In demonstrating an improvement in patient symptoms after decompression, we identify this neurovascular conflict as a potential intrapelvic cause of sciatica. This study is a retrospective case series (Canadian Task Force Classification II-3). Nerve decompression laparoscopies were performed in S\u00e3o Paulo, Brazil. Thirteen female patients undergoing laparoscopy for sciatica with no clear spinal or musculoskeletal causes were included in this study. In all cases, we identified LS entrapment by aberrant SGVs, and performed decompression by vessel ligation. The average preoperative visual analog scale score of 9.62 \u00b1 0.77 decreased significantly to 2.54 \u00b1 2.88 post-operatively (P &lt; 0.001). The success rate (defined as \u2265 50% improvement in visual analog scale score) was 92.3%, over a follow-up of 13.2 \u00b1 10.6 months. Our case series demonstrates a high success rate and significant decrease in pain scores after laparoscopic intrapelvic decompression, thereby identifying pelvic nerve entrapment by aberrant SGVs as a potential yet previously unrecognized cause of sciatica. This intrapelvic neurovascular conflict\u2014the SGV syndrome\u2014should be considered in cases of sciatica with no identifiable spinal or musculoskeletal etiology.<\/jats:p>","DOI":"10.1093\/jhps\/hnz012","type":"journal-article","created":{"date-parts":[[2019,3,25]],"date-time":"2019-03-25T08:00:27Z","timestamp":1553500827000},"page":"104-108","source":"Crossref","is-referenced-by-count":15,"title":["Superior
