Intracoronary Palmaz-Schatz stent placement after complicated angioplasty: medium term follow-up.
Acute or impending coronary artery occlusion during percutaneous coronary balloon angioplasty represents a serious and potentially life-threatening complication. We studied the clinical and angiographic outcome in 21 patients who underwent emergent intracoronary Palmaz-Schatz stent implantation (11 due to persistent residual stenosis and 10 due to flow-limiting dissection) during complicated balloon angioplasty and who were followed for a mean period of 7.9 +/- 5.7 months. Excluding one patient lost to follow-up, the event-free survival rate was 70%. Six (30%) patients developed adverse clinical events. One died and 3 required elective revascularization procedures. One subacute stent thrombosis was documented. Acute Q-wave myocardial infarction occurred in 2 patients. Among 9 patients studied angiographically 5.6 +/- 2.5 months after stent placement, 2 had developed restenosis (> 50% luminal narrowing). Eleven have remained essentially symptom free. For selected patients, emergent deployment of a Palmaz-Schatz coronary stent, following complicated balloon angioplasty, offers satisfactory long-term results, thus obviating the need for a high risk emergency bypass surgery.
