We present 6-month follow-up of 435 patients undergoing stent deployment. Forty-four patients were referred because of myocardial ischemia related to the stented artery. In six of these patients (14%), the stented vessel revealed a new proximal lesion separated from the stented portion, which warranted further intervention. It is felt that these new lesions are related to the stenting technique as a result of local trauma induced from the guiding catheter.
我们对435例行支架植入术的患者进行了6个月的随访。44例患者因与支架置入动脉相关的心肌缺血而被转诊。在这些患者中，有6例（14%）的支架血管显示出一个与支架部分分离的新的近端病变，这需要进一步干预。据认为，这些新病变与支架置入技术有关，是由引导导管引起的局部创伤所致。
