The aim of the study was to demonstrate the utility of endovascular stent-graft repair for emergency management of aorto-iliac surgery complications. Between 1997 and 2004, in our institute, 201 patients underwent transluminal endovascular graft placement. In 3 patients (1.4%), previously submitted to conventional aortic surgery, endovascular treatment was carried out due to the occurrence of late complications: 1 secondary aortocaval fistula, 1 impending rupture of aortic pseudoaneurysm and 1 secondary aorto-enteric fistula. All candidates were high surgical risk patients (ASA III-IV) suitable for endoprosthesis positioning by endovascular stent-graft implantation presenting with severe worsening conditions in an emergency situation. The patients were treated under local anesthesia and mild sedation. After treatment there was complete resolution of the clinical presentation and an improvement of general conditions in all 3 patients. In the 1st patient legs edema disappeared and in the 2nd patient mesogastric pain is absent, respectively at 30 and 8 months. The 3rd patient, with secondary aorto-enteric fistula, was submitted 2 months later to aortic graft removal and axillo-bifemoral bypass because of infection development. For the treatment of abdominal aortic surgery complications in high risk patients, particularly in emergency situations, endovascular approach is a feasible and safe alternative to conventional open repair. Further evaluation of this technique and longer follow-up will determine its exact role in the management of these life-threatening complications.
