[Excimer-laser angioplasty for the treatment of restenosis after Wiktor and Gianturco-Roubin stent placement. A new therapeutic alternative].
We report the use of excimer-laser angioplasty for the treatment of Wiktor and Gianturco-Roubin in-stent restenosis of in two patients. Case 1-a 48-year-old man presented unstable angina five months after Wiktor stent was deployed in right coronary artery. Cardiac catheterization revealed stenosis (95%) within the stent. Case 2-a 65-year-old man presented stable angina four months after Gianturco-Roubin stent was deployed in left anterior descending artery. Cardiac catheterization revealed stenosis (80%) within the stent. Excimer-laser angioplasty within the stent reduced the stenosis to 19% and 30%, respectively. The patients recovered and currently, six months post-procedure, are free of chest pain, and cardiac catheterization revealed stenosis to 30% and 35%, respectively, within the stent. Therefore, the procedure was an effective means of treating restenosis after coronary stent placement, and a prospective comparison of excimer-laser angioplasty and other management alternatives to in-stent restenosis is needed.
