[Coronary endoprosthesis. Short- and mid-term results].

Mechanical stenting of the coronary wall by an endoprosthesis is a method of treating and preventing the 2 major complications of balloon angioplasty: acute occlusion by dissection and secondary restenosis. Forty-four self expanding stents were implanted in 42 patients presenting with post-angioplasty restenosis (35 cases), stenosis of an aortocoronary bypass graft (4 cases) or symptomatic post-angioplasty coronary dissection (3 cases). The primary results featured a high early occlusion rate of the endoprosthesis (28.

[Early reocclusion after in situ coronary desobstruction either with streptokinase or angioplasty during the acute phase of myocardial infarction].

The aim of this study was to assess the incidence of early reocclusion after therapeutic reperfusion of coronary arteries in acute myocardial infarction. Seventy four patients underwent intracoronary thrombolysis and 133 patients had immediate coronary angioplasty. The success rates were 70 per cent and 86 per cent respectively (p less than 0.
