Aortic quadfurcation with persistent left sciatic artery: an extremely rare anatomic variant in a 3-year-old boy.

Reports of aortoiliac variant anatomy are rare, especially in the pediatric population. A 3-year-old male patient with hypertension and left foot polydactyly with syndactyly was referred to our interventional radiology service for evaluation of a possible renovascular cause of the hypertension. Angiograms revealed an extremely rare anatomic variant consisting of the absence of the common iliac arteries bilaterally, resulting from quadfurcation of the abdominal aorta into the bilateral internal and external iliac arteries. Additionally, a persistent left sciatic artery was identified.
