Endovascular Repair of Descending Thoracic Aorta in Loeys-Dietz II Syndrome

Loeys-Dietz syndrome (LDS) is an autosomal dominant disorder that is predominantly characterized by involvement of the aorta, manifesting as aneurysmal dilatation or aortic dissection. Patients with LDS manifest with spontaneous aneurysms and dissections of central and peripheral arterial beds. We present 2 cases of young male patients with Loeys-Dietz II aortopathy, who manifested with spontaneous intimal tear of descending thoracic aorta and contained aortic rupture. Both patients were managed by endovascular repair, with collaborative efforts of teams comprising interventional cardiologists and radiologists, and a vascular surgeon.
