摘要
目的 :评价长支架治疗冠状动脉长病变的疗效。方法 :回顾性分析 1996年 1月～ 1999年 1月接受冠状动脉内支架术治疗患者的临床资料。各例以标准方法行冠状动脉造影和介入治疗。手术成功标准为 :残余狭窄 <30 % ,TIMI血流 3级 ,且无围术期严重并发症 (死亡或心肌梗死 )。结果 :340例共植入 375个冠状动脉内支架 ,其中 76例接受长支架 (≥ 2 0 m m)治疗 (共植入支架 79个 ) ( 组 )。另 2 6 4例中 ,支架长度为一般均 <2 0 mm( 组 )。 组的支架直径为 (3.0 2± 0 .39) m m,长度为 (2 4.95± 4.40 ) mm , 组的支架直径为 (3.0 3± 0 .36 ) mm ,长度为(13.5 4± 3.34) mm。两组的手术成功率相似 (98.7%和 99.6 % ) ; 组手术时的并发症 (血栓、严重夹层撕裂 )的发生率较 组有显著增高 (10 .1%和 1.9% ,P <0 .0 1) ;但两组患者在住院期间均无严重心脏事件发生。结论 :长支架治疗冠状动脉长病变成功率高 ,短期疗效确切 。
Objective:To evaluate efficacy of long stent in the treatment of long coronary artery lesion.Method:Three hundred and fourty patients who underwent intracoronary stenting between January 1996 and January 1999 were retrospectively reviewed.Coronary angiography and interventional treatment were performed by standard techenique.The criteria of procedural success included residual stenosis<30%,TIMI flow grade III and no periprocedural major cardiac events(death or myocardial infarction).Result:340 patients were implanted with 375 stents.Amount the total patients,76 patients were treated with 79 long stents(≥ 20 mm)(group I)and in the remaining 264 patients were implanted tents with length than 20 mm(group Ⅱ).The mean diameter and length of the stents were ( 3.02 ± 0.39 ) mm and ( 24.95 ± 4.40 )mm for group I and ( 3.03 ± 0.36 ) mm and ( 13.54 ± 3.34 )mm for group Ⅱ.The procedural success rate was similar in the two groups( 98.7 % and 99.6 %,respectively),but incidence of thrombus formation and severe ruptures of disection during the procedures was higher in group I than in group Ⅱ( 10.1 % and 1.9 %,P< 0.01 ).No major cardiac events(death or myocardial infarction)occurred during hospitalization in the two groups.Conclusion:Long stent implantation has high success rate.It provides short-term efficacy in the treatment of long coronary artery lesions,despite a slightly high complication rate during stent implantation.
