Anatomical variations of the principal nutrient pedicle for iliac crest graft: the ilio-lumbar artery

The complete anatomy of the iliolumbar artery: a meta-analysis with clinical implications

“…The blood from the abdominal aorta flows into the umbilical artery through the plexus in a caudal direction, leading to the caudal migration of the said vessel. This caudal migration potentially accounts for the variations observed in the branches of the internal iliac artery, including the ILA [14,27].…”

Anatomical Variation of Iliolumbar Artery and its Clinical Significance

“…The variability in branching of the iliolumbar artery (ILA) has significant value in anatomy, medicine and in surgery, of course, because it is the very important for nutrition of the ilium bone as well as for collateral blood supply to the lower extremity in case of occlusion of the external iliac artery via anastomosis with a deep circumflex ilium artery. The ILA is used in various surgical manipulations that approach the sacroiliac joint or connections between lower lumbar vertebrae [3,4], in procedures of embolization [5][6][7][8][9]. Besides, variability of the iliolumbar artery needs to keep in mind in its use as feeding pedicle in bone flaps [6].…”
