摘 要:目的比较对吻支架术与单支架术治疗血管直径较大真性分叉病变的远期疗效。方法380例分叉病变患者随机分为对吻支架术组190例,单支架术组190例,分别行对吻支架术或单支架术。随访1年,观察再狭窄、死亡、非致死性心肌梗死、靶病变再次血运重建、支架内血栓形成、手术成功率和手术时间。结果单支架组中32例(16.8%)因术中分支出现夹层或血流低于TIMI3级改行T型支架植入,因此最终158例完成了试验(单支架手术成功率83.2%);而对吻支架组都按既定方案完成了手术(手术成功率100%,x2=32.79,P〈0.05)。术后1年,对吻支架组与单支架组比较总体再狭窄[30(15.8%)与24(15.2%);X2=0.000,P〉0.05];主支再狭窄[20(10.5%)与16(10.1%);X2=0.003,P〉0.05]、分支再狭窄[13(6.8%)与23(14.6%);x2=4.73,P〈0.05]、死亡[2(1.1%)与1(0.6%);0=0.026,P〉0.05]、心肌梗塞[4(2.1%)与2(1.3%);X2=0.034,P〉0.05]、靶病变再次血运重建[23(12.1%)与20(12.7%);X2=0.000,P〉0.05]、支架内血栓[4(2.1%)与2(1.3%);X2=0.034,P)’0.05]、手术时间[(20±8)min与(45±9)min;t=1.98,P〈0.05]。结论对于血管直径较大的真性分叉病变,对吻支架技术远期疗效与单支架术相近,但手术成功率更高、手术时间更短。Objective To evaluate long-term outcome of simultaneous kissing sirolimus-eluting stent (SKS) technique versus single sirolimus-eluting stent (SSS) technique for percutaneous treatment of true coronary bifurcation lesions in )arge-size vessels. Methods This randomized study assigned 190 patients with a coronary bifurcation lesion to simultaneous kissing stenting (SKS) in both main and side branches and 190 patients to main vessel stenting only (SSS). The endpoints included restenosis, death, non-fatal myocardial infarction, target-lesion revascularization (TLR), stent thrombosis, success rate of pereutaneous coronary intervention (PCI) and the operation duration. Results During 1-year follow-up, the SKS group and the SSS group had similar incidences of overall restenosis [30( 15.8% ) vs. 24( 15.2% ) ,X2 =0. 000 ,P 〈0. 05] ,main- branch restenosis [ 20 ( 10. 5 % ) vs. 16 ( 10. 1% ), X2 = 0. 003, P 〉 0. 05 ] ; side-branch restenosis [ 13 ( 6. 8 % ) vs. 23 ( 14. 6% ) ; X2 = 4. 73, P 〈 0. 05 ] ; death [ 2 ( 1.1% ) vs. 1 ( 0. 6% ), X2 = 0. 026, P 〉 0. 05 ], non-fatal myocardial infarction [ 4 ( 2. 1% ) vs. 2 ( 1.3 % ), X2 = 0. 034, P 〉 0. 05 ], TLR [ 23 ( 12. 1% ) vs. 20 ( 12. 7% ), X2 = 0. 000, P 〉0. 05 ] and stent thrombosis [ 4 ( 2. 1% ) vs. 2 ( 1.3% ), X2 = 0. 034, P 〉 0. 05 ] and a shorter operation duration[ (20 +8) min vs. (45 ±9) min,t = 1.98,P 〈0.05]than the SSS group. Conclusion For true coronary bifurcation lesions in large-size vessels, SKS and SSS have similar long-term outcomes. The SKS group has a higher success rate of PCI and shorter operation duration.
