Résumé
Objective To study the incidence and the effect of intracoronary stenting for spontaneous coronary artery dissection (SCAD). Methods Data from coronary angiography performed in 2?216 patients were analyzed to discover SCAD. Intracoronary stents were implanted in the patients with SCAD suited for percutaneous coronary intervention (PCI). Aspirin, clopidogrel, heparin or low molecular weight heparin were used on demand during the operation-around period. Results Twenty-six cases of SCAD [19 males, 7 females, mean age (60.9?11.6) years] were discovered. The incidence was 1.17%. Among the 26 patients, 15 suffered from acute myocardial infarction and 11 unstable angina. SCAD occurred in 28 blood vessels of the 26 cases, of which, 1 was in LM, 9 in LAD, 4 in LCX and 14 in RCA. Twenty-three stents were implanted in 19 coronary arteries of 18 patients (15 stentings after PTCA and 4 direct stentings). After PCI, remaining stenosis of one SCAD lesion was
