Tratamiento del aneurisma aórtico abdominal por vía endovascular: experiencia inicial

Background: Thirty day mortality of current surgical treatment of abdominal aortic aneurysm is 0.7 to 5 percent. Coronary artery disease is the main risk factor in this elderly population. An alternative procedure based on the transfemoral deployment of self expandable prostheses to exclude the aneurysm, avoids a laparotomy and major surgical trauma, reducing the risks of the conventional operation. Aim: To report our experience on endovascular repair of abdominal aortic aneurysms. Patients and methods: Nine consecutive patients aged 66 to 82 years old, possible candidates for the procedure, were studied. Results: Only four patients fulfilled the requirements for the procedure, which was technically successful in three. One patient was converted to an open surgical repair. Patients were discharged 72-96 hours after graft implantation. The postoperative CAT scan confirmed total exclusion of the aneurysm by the endovascular graft. All nine patients are alive at the time of this report. Conclusions: Given certain anatomical conditions, endovascular treatment of abdominal aortic aneurysms is an attractive alternative for high risk patients
