title: [Long-term results of transluminal coronary angioplasty of chronic coronary artery occlusions].
abstract: In 43 patients an occlusion of the coronary artery, which had occurred a few weeks or months previously, was diagnosed between 1977 and 1983. Angiograms were available prior to the occlusion in 35 patients but not in 8 patients. In 31 patients mechanical revascularization was attempted with acute success in 42 percent of the patients. The primary success rate in a control population without occlusion but high-grade stenoses at similar sites was 83 percent. Reocclusions or high-grade restenoses occurred in 54 percent of the revascularized vessels. Taking into account successful repeated dilatations, 62 percent of the successfully treated patients showed long-term success a year after intervention. With reference to all patients in whom revascularization had been attempted, the long-term success rate was 26 percent. Hence, mechanical revascularization of subacute and chronic artery occlusions by angioplasty shows much less chance of acute success together with a markedly increased restenosis rate compared to angioplasty of chronic stenoses. Regarding the good long-term results in a quarter of patients, the technically unproblematic approach as well as minimal dangers for the patients, a revascularization attempt seems to be justified in corresponding clinical presentations.
