Marfan syndrome is a well-described autosomal dominant connective tissue disorder with a constellation of anatomic characteristics including aortic degeneration as a result of the spontaneous mutation of the fibrillin gene, FBN1. Whereas life-threatening dissection and ascending aneurysmal rupture have been thoroughly documented in the literature, aneurysms of the abdominal aorta and those present in the pediatric population have only rarely been reported. In this case report, we describe presentation, successful open surgical repair, and recovery of a pediatric Marfan syndrome patient with a ruptured abdominal aortic aneurysm.
