Aortic dissection: a rare complication of osteogenesis imperfecta.
Osteogenesis imperfecta (OI) is an inherited connective tissue disorder, a group that includes Ehlers-Danlos syndrome, Marfan's syndrome and pseudoxanthoma elasticum. OI is a heterogeneous disease of collagen I biosynthesis characterized by variable clinical phenotypes, including skeletal and cardiovascular manifestations. A 65-year-old man with OI who had extensive prior successful cardiac valve surgeries is described. He survived for 18 years after his initial valve surgery, but died of multiorgan failure and sepsis after repair of a spontaneous type A aortic dissection. This is the fourth reported case of aortic dissection secondary to OI and illustrates the extensive cardiovascular pathology associated with OI. Aggressive management of arterial dissection risk factors, such as systemic arterial hypertension, is advocated for patients with OI.
