title: [Non-surgical treatment of aortic aneurysms and dissections: indications, strategies and outcome].
abstract: OBJECTIVE
  The endovascular treatment of the thoracic aorta is an effective alternative to open surgical repair and offers a therapeutic option even to patients at high risk for surgery. Our experience in the treatment of different diseases of descending thoracic aorta is reported.
  
  
  METHODS
  Between July 1997 and January 2001, 50 patients were selected for endovascular treatment: 36/50 patients presented high risk for conventional surgery. Six patients presented clinical and imaging features suggesting impending rupture and were treated on emergency basis. The stent-graft prosthesis was individually manufactured or selected on the basis of spiral CT or MRI measurements.
  
  
  RESULTS
  Endovascular stent positioning and deployment was technically successful in 49 cases. In one patient the tortuosity of the aortic arch prevented graft deployment. Complete aneurysm exclusion was achieved in 48 cases as assessed by post-procedure angiography and TEE. One proximal endoleak was noted and surgical conversion was performed 40 days later. There were no intraoperative mortality or complications. One patient presented extension of dissection at the 8th postoperative day and required of surgical repair. CT scan showed an endoleak in 4 cases that sealed spontaneously in three cases while the fourth case was treated by graft extension. In the long term two secondary endoleak were observed (12 and 24 months after the procedure).
  
  
  CONCLUSIONS
  Endovascular stent-graft repair provides a less invasive opportunity to patients affected by thoracic aortic disease. Careful cases selection is the first postulate for the efficacy and safety of the procedure.
