Trombose coronariana tardia secundária a implante de stent com paclitaxel sem reestenose dos stents convencionais Late coronary thrombosis secondary to implantation of paclitaxel-eluting stent without restenosis of conventional stents

Abstract

Homem de 39 anos com angina pós-infarto. Coronariografia demonstrou: obstrução total proximal da artéria coronária direita (ACD), lesões obstrutivas de 95% na artéria descendente anterior (ADA), 80% no 2° ramo marginal esquerdo (ME) e 95% na artéria circunflexa (ACX). O paciente foi submetido a implante de stent TAXUS 3,0 x 24 mm e stent EXPRESS 2,75 x 24 mm nos terços proximal e distal da ACD, respectivamente, e stent INFINNIUM 3,0 x 24 mm na ADA com sucesso. Após 7 meses, apresentou IAM anterior por trombose do stent INFINNIUM e reestenose do stent TAXUS, sem perda de resultado nos stents convencionais.A male 39 year-old patient with post-infarction angina. The coronary angiography showed total proximal obstruction of right coronary artery (RCA), obstructive lesions of 95% of the anterior descending artery (ADA), 80% of the second left marginal branch (LM2), and 95% of the circumflex artery (CXA). The patient was successfully implanted with a Taxus 3.0 x 24 mm stent and an Express 2.75 x 24 mm stent in the proximal and distal thirds of the RCA, respectively, and with an Infinnium 3.0 x 24 mm stent in the ADA. After seven months, the patient had an anterior acute myocardial infarct (AMI) due to thrombosis of the Infinnium stent and restenosis of the Taxus stent, with no loss of results in the conventional stents.
