    Abstract:
    The rate of morbidity and mortality in patients undergoing open repair for thoracoabdominal aortic aneurysm (TAAA) still remains too high, ranging from 2% to 40%. In recent years "hybrid" techniques have been developed (EVAR and retrograde surgical revascularization) for the treatment of TAAA. This procedure has proved to be more effective to reduce the high risks of complication related to this kind of operation resulting in a lower morbidity and mortality rates when compared to traditional surgical techniques. A 77-year old patient who had previously been undergone surgical exclusion of a TAAA by using a straight aorto to aortic bypass graft (end to end fashion) with visceral patch, was referred to our behalf for the presence of a recurrent Crawford Type IV aortic aneurysm expansion of 10.5 cm length on diameter. Considering the serious co-morbidities of the patient and the high risk of mortality related to the traditional redo surgery, the hybrid technique was considered to repair this recurrent aneurysm by using a surgical debranching of the visceral and renal arteries from the aorta associated to the their retrograde revascularization before to perform the endovascular exclusion of the aneurysm at the same time in a single operation. Over a period of 12 months the patient was alive in good health, a follow-up by computed tomography (CT) scan confirmed the correct position of the endograft, without endoleaks, the patency of the bypasses and the reduction on diameter of the aneurysmal sac. The combined hybrid procedure (endovascular and open surgical approach) for treatment of complex TAAA is to be considered a feasible and effective surgical technique, but a larger number of cases and a longer follow-up are required either to validate this procedure or to get a more significant and statistical comparison to the traditional approach.
