Abstract:
Primary congenital abdominal aortic aneurysm is an extremely rare entity, with only 15 patients reported in the literature. Options for repair are often limited secondary to branch vessel size and other anatomic limitations. We present a neonate diagnosed with an abdominal aortic aneurysm on prenatal ultrasound. A postpartum computed tomography angiogram revealed an extensive type IV thoracoabdominal aortic aneurysm extending to the aortic bifurcation and resulting in bilateral renal artery stenosis. The unique features of this patient and challenges in management are discussed.
