Hybrid Surgery/therapy in a Complex Thoracoabdominal Aortic Aneurysm – Case Report

Frequency The prevalence of aortic aneurysms is higher than 3-4% in persons over 65 and over the last 30 years the overall prevalence has increased significantly. The estimated incidence of thoracic aortic aneurysms is 6 cases per 100.000 person/years. Classification Thoracic aneurysms (TAA) are subdivided into 3 groups depending on location: n aneurysm of ascending aorta+/-valvular lesion named by Cooley anuloaortic ectasia (associated frequently with Marfan syndrome); n aneurysm of aortic arch; n aneurysm of descending thoracic aorta (the most frequent type).
