A rare genetic vascular disease characterized by the familial occurrence of thoracic aortic aneurysm, dissection or dilatation affecting one or more aortic segments (aortic root, ascending aorta, arch or descending aorta) in the absence of any other associated disease. Depending on the size, location and progression rate of dilatation/dissection, patients may be asymptomatic or may present dyspnea, cough, jaw, neck, chest or back pain, head, neck or upper limb edema, difficulty swallowing, voice hoarseness, pale skin, faint pulse and/or numbness/tingling in limbs. Patients have increased risk of presenting life threatening aortic rupture.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
2 clinical trials registered. Interventions under study include other interventions. Research is primarily sponsored by academic and government institutions.
9 publications have been identified in PubMed for familial thoracic aortic aneurysm and aortic dissection. Research spans Basic Science / Preclinical (33%), Review / Meta-Analysis (22%), and Case Report / Case Series (22%).
