Thoracic endovascular aortic repair for high-risk Stanford type B aortic dissection in a 15-year-old patient with genetic mutations: a case report with follow-up of four years

This case report presents mid- to long-term outcomes of thoracic endovascular aortic repair for high-risk type B aortic dissection in a 15-year-old patient with myosin heavy chain protein 11 genetic mutations. A CT scan showed the primary entry tear located on the lesser curvature near the left subclavian artery, and the dissection originated from the descending aorta to the abdominal aorta, accompanied by 80% narrowing of the true lumen. Following successful endovascular therapy using stent-grafts, the patient recovered well. A four-year follow-up CT scan showed significant thoracic aorta remodelling.
