Abstract

AIM:

The endoluminal stent-grafting represents an alternative to surgery in the treatment of lesions of the descending thoracic aorta. The purpose of the present study was to evaluate the mid-term results of the Talent stent-graft in the different indications of aortic disease and the use of magnetic resonance angiography (MRA) in the diagnosis of complications.

METHODS:

Over a 3-year period, 23 patients with a high surgical risk and presenting a localized lesion of the descending thoracic aorta had an implantation of a Talent stent-graft. Indications were degenerative aneurysm (n=13), false aneurysm (n=7) and penetrating atherosclerotic ulcer (n=3). The feasibility of the endovascular treatment and sizing of the aorta and stent-grafts were determined pre-operatively by MRA and intraoperative angiography. Immediate and mid-term technical and clinical success were assessed by clinical and MRA follow-up.

RESULTS:

Endovascular treatment was completed successfully in all patients with no conversion to open repair. There was no intraoperative mortality. The mean operative time was 38+/-7 min. Primary success rate was 100%. We didn't have perioperative mortality. The mean follow-up period was 15+/-5 months. The survival rate was 97% (n=22). Regression of the aneurysmal size was observed in 70% (n=16). MRA diagnosed 3 over 4 postoperative endoleaks that were not diagnosed with the CT-scan, and did not interfere with the nitinol structure of the stent-graft.

CONCLUSIONS:

Endovascular treatment of the various localized diseases of the descending thoracic aorta is a promising, feasible, alternative technique to open surgery in well selected patients. MRA is well adapted to diagnose postoperative endoleaks.
