title: [Primary coronary stent implantation in complex morphology of stenosis or unsatisfactory results of angioplasty].
abstract: Early and late results of coronary angioplasty are influenced by the morphology of the coronary artery stenosis. Primary implantation of a balloon-expandable Palmaz-Schatz stent was indicated in 37 patients (31 men and 6 women; mean age 57 +/- 2 years) with symptomatic coronary heart disease and complex morphology of the stenosis. Intracoronary stents were successfully placed in 30 of 37 patients, without complications in all but one. This patient developed a thrombotic occlusion of the vessel 3 days after the procedure which, despite high-dosage thrombolysis treatment, resulted in an anterior wall myocardial infarction. A repeat angiography has since been performed (3-7 months after the procedure) in 25 of the 29 patients with a complication-free course. In 19 of the 25 patients the site of implantation was smooth, while a silent re-occlusion had occurred in one after successful recanalization of a chronic occlusion. Two patients had a subtotal restenosis (12% angiographic restenosis rate). These data indicate that intracoronary stent implantation improves the morphological results after balloon dilatation and reduces the restenosis rate.
