ESCLUSIONE ENDOVASCOLARE DI ANEURISMI AORTICI TORACO-ADDOMINALI

Endovascular Exclusion of Thoracoabdominal Aortic Aneurysm - The traditional open surgical repair of thoracoabdominal aortic aneurysms, affecting the part of the aorta giving rise to the visceral arteries to abdominal organs and radicularis magna artery to the spinal cord, is still burdened with high operative morbidity and mortality. Many patients are also excluded from intervention due to high surgical risk, for age and comorbid conditions. Endovascular surgery, performed through peripheral arteries under fluoroscopic control, is well tolerated by high-risk patients. It realizes exclusion of the aneurysm and revascularization of pe- ripheric and visceral branches using fenestrated or branched endografts, or chimney technique. The improvements of a two-stage endovascular procedure, and careful neurologic and hemodynamic intraoperative monitoring allow morbidity and mortality comparable to the best centers of open surgery. The case studies we show report 11 patients treated by endovascular exclusion of the thoracoabdo- minal aneurysm with 0 % mortality and 0 % spinal cord ischemia.
