ABSTRACT

During routine dissection class, we encountered a variation of neurovascular structures of pelvis on 70 year old male cadaver. We observed bilateral variant pattern of structures that were deeply situated on lumbosacral triangle (LST), over ala of sacrum. The iliolumbar artery (ILA) arose directly from common iliac artery and lumbosacral trunk (LST) was formed at a lower level. So, the final arrangement on ala of sacrum from medial to lateral aspect were- sympathetic trunk, ventral ramus of L5, lateral sacral artery (LSA), lower division of ventral ramus of L4 nerve and obturator nerve. Better understanding of these variations will lead to greater success and helpful for clinicians, medical students and reasearchers.

Keywords: Iliolumbar artery, Lumbosacral triangle, Ventral ramus, Ala of Sacrum.
