Endoprótesis aortouniilíaca como alternativa a la cirugía abierta en el remodelado de las endoprótesis de aorta abdominal

Results of the review produced five cases of important prosthetic remodelling that entailed conversion to aortouniiliac stent-grafts and extra-anatomical bypasses. Mean age was 73.4 years and the most frequent risk factors were arterial hypertension and ischaemic heart disease. In all the cases of conversion, the previous stent-graft was the Vanguard and the types of AAA that were treated were B and C. Less important complications included one case of inguinal lymphorrhagia and the more complicated cases included a thrombosis of the crossed bypass and stent-graft, which were salvaged using fibrinolysis. Computed tomography scanning of the abdomen performed at two years revealed the absence of leaks and a reduction in the diameter of the aneurysmal sac. There were no conversions to open surgery. Conclusions. Aortouniiliac stent-grafts in association with a femorofemoral crossover bypass represent a way of treating severe stent-graft remodelling with a lower morbidity and mortality rate than open surgery. This technique also seems to reduce the chances of further remodelling being required.
