冠状动脉内支架置入术在B型与C型冠状动脉病变患者中的应用

７例１２处Ｂ型与Ｃ型冠脉病变经球囊预扩张后，４处冠状动脉内膜夹层形成，２处血管弹性回缩而置入支架；６处直接置入支架。术后造影内膜夹层及血管弹性回缩消失，全部病例扩张满意，血流改善充分。１例术后并发出血，处理后康复。随诊１～２４月，１例术后２月再发心绞痛，药物能缓解。

THE APPLICATION OF INTRACORONARY STENTING TO TYPE B AND C LESIONS OF CORONARY ARTERIES

Intracoronary stenting was introduced to 4 lesions due to coronary arterial dissections and to 2 lesions owing to elastic recoil of coronary arteries and stent placement was directly performed in 6 complex coronary lesions after 12 target lesions from 7 patients with Types B and C lesions of coronary arteries had been pre dilated with balloon. Coronary angiography showed that dissections and recoils had disappeared. Target lesions were well dilated and blood flow was well improved in all cases, one patient was complicated with hemorrhage which was cured quickly. During the follow up period of 1 to 24 months, another case had recurrence of angina after 2 months of stenting which could be controlled with anti angina agents. These indicate that intracoronary stenting had good therapeutic effect and is considered as a safe, fast and effective method in dealing with acute complications of coronary artery after routine PTCA.
