title: Should Endovascular Therapy Be Considered for Patients With Connective Tissue Disorder?
abstract: Because of early diagnosis, strict imaging follow-up, and advances in medical and surgical management, life expectancy of Marfan patients has dramatically improved since the 1970s. Although disease of the root and ascending aorta are more frequent in patients with connective tissue disorders, a subset of patients present with diffuse disease that might involve any portion of the thoracoabdominal aorta. Thoracic endovascular aortic repair (TEVAR) has gained widespread acceptance for the treatment of different pathologies of the descending aorta. In contrast, TEVAR in patients with connective tissue disorders is associated with a high risk of early and mid-term complications and reinterventions. Currently, a consensus of experts recommend that an open approach should be reserved for use in acceptable risk candidates with connective tissue disorders. TEVAR should be considered solely in patients in a complex repeat surgical setting or in patients judged to have prohibitive open surgical risk. Finally, as a bridge to a definite open repair, TEVAR might be life-saving in patients with connective tissue disorders who present with exsanguination or severe malperfusion. Future developments in stent-graft technology might decrease stent-graft-related complications in patients with connective tissue disorders, although securing a device with radial force in a fragile aorta in the long-term will be challenging.
