[Utilization of self-expandable prosthesis (stent) introduced through the femoral artery for treatment of dissection of the descending aorta].
OBJECTIVE
We present four cases of dissection of the thoracic descending aorta that underwent treatment with an auto expandable dácron-covered stent.


METHODS
The stent was deployed through the femoral artery in the hemodynamic laboratory after sedation, local anesthesia in both inguinal areas and systemic heparinization. The catheter with the stent was introduced through a cutdown in the left femoral artery until the area in the thoracic aorta with the previously diagnosed tear.


RESULTS
The stent was expanded with immediate occlusion of the false lumen. The whole procedure took 90 minutes and the patients were discharged without complications.


CONCLUSIONS
Stent utilization is an important step to improve treatment results in type B aortic dissection.
