[Percutaneous transluminal angioplasty in vascular by-passes]

Results from 21 cases of percutaneous transluminal angioplasties as a treatment of stenosed vascular by-pass from 16 patients, are presented. The technique took place in 10 cases at the aorto-femoral area, in others 10 cases at the popliteal-femoral area and, in the last one, at the carotid-subclavian area. Preliminary results were successful in all cases (100%). Follow-up showed a better long-term results at the aorto-femoral level. Considering the satisfactory results and also considering that, in case of negative results or re-stenosis, other surgical techniques could be performed, we conclude that the percutaneous transluminal angioplasty should be the first treatment for such of injuries.
