Abstract

Congenital anatomical variations of the terminal aorta are rare. Given the increasing number of endovascular and laparoscopic procedures, such variations are likely to assume greater clinical significance. A 15-year-old male sustained a pelvic vascular injury following a stab to the left gluteus. Computed tomographic angiography and digital subtraction angiography demonstrated a left superior gluteal artery pseudoaneurysm and absence of the common iliac arteries consistent with congenital quadrifurcation of the terminal aorta. The patient was subsequently treated with endovascular coil embolisation with a good angiographic and clinical outcome.

Contribution: Terminal aortic variants are rare and given the increasing number of interventional endovascular procedures performed in the aorta, an awareness of the potential anatomical configurations of the distal aortic branches is of increasing relevance. The authors describe the imaging findings of one such anatomical variant.
