ABSTRACT
Surgical treatment of thoracoabdominal aneurysms is a big technical challenge with a high rate of complications and mortality. It requires a large exposure and transient interruption of vital organ perfusion during its repair. Endovascular repair is a less invasive alternative available over the last decade. We report four male patients aged 44 to 76 years, with thoracic aortic aneurysms and involvement of visceral aorta, treated with a two stage procedure. During the first stage, a retrograde revascularization of the superior mesenteric and renal arteries from the infrarenal aorta was done, associated in two cases to a concomitant repair of an infrarenal aortic aneurysm. In the second stage, an endovascular graft was placed through the femoral artery, from the segment proximal to the aneurysm to the infrarenal aorta, above the origin of the visceral artery reconstructions, excluding the aneurysm from circulation. In one patient, both stages were concomitant and in three the second stage was delayed. One patient presented a postoperative bleeding that required reintervention without adverse consequences. No patient died, presented paraplegia or deterioration of renal function. After follow up of 6 to 20 months, there is no evidence of aneurysm growth or complications derived from the procedure.
