摘要:目的 ?觀察研究腦血管藥物洗脫支架與金屬裸支架治療椎動脈狹窄的臨床療效。方法 ?選取2018年2月~2019年2月在我院診治的104例椎動脈狹窄患者為研究對象,采用隨機數(shù)字表法分為對照組和觀察組,各52例。對照組采用金屬裸支架治療,觀察組采用腦血管藥物洗脫支架治療,比較術(shù)后6個月支架內(nèi)再狹窄發(fā)生率、血流動力學(xué)指標(biāo)改變(狹窄處峰值流速、狹窄處阻力指數(shù)、患側(cè)寰椎段阻力指數(shù))情況、Malek分級以及并發(fā)癥發(fā)生情況。結(jié)果 ?術(shù)后6個月觀察組支架內(nèi)再狹窄發(fā)生率為7.67%,低于對照組的21.15%,差異有統(tǒng)計學(xué)意義(P<0.05);觀察組狹窄處峰值流速、狹窄處阻力指數(shù)、患側(cè)寰椎段阻力指數(shù)均低于對照組,差異有統(tǒng)計學(xué)意義(P<0.05);觀察組Malek分級1級、2級分布率高于對照組,3級、4級低于對照組,差異有統(tǒng)計學(xué)意義(P<0.05);觀察組并發(fā)癥發(fā)生率為3.84%,低于對照組的11.53%,差異有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論 ?腦血管藥物洗脫支架治療椎動脈狹窄與金屬裸支架比較,支架內(nèi)再狹窄發(fā)生率低,可顯著改善患者狹窄處血流動力學(xué),且并發(fā)癥少,應(yīng)用安全性高,值得臨床應(yīng)用。

Abstract:Objective ?To observe and study the clinical efficacy of cerebrovascular drug-eluting stents and bare metal stents in the treatment of vertebral artery stenosis.Methods ?A total of 104 patients with vertebral artery stenosis who were diagnosed and treated in our hospital from February 2018 to February 2019 were selected as the research objects. They were divided into a control group and an observation group by a random number table method, with 52 cases in each group.The control group was treated with bare metal stent, observation group was treated with cerebrovascular drug-eluting stent. the incidence of restenosis in the stent, hemodynamic changes (peak velocity at stenosis, resistance index at stenosis, resistance index at atlantoaxial segment of affected side), Malek grade and complications were compared after 6 months.Results ?6 months postoperatively, the incidence of restenosis in the stent in the observation group was 7.67%, which was lower than 21.15% in the control group,the difference was statistically significant (P<0.05); The resistance index of lateral atlas was lower than that of the control group,the difference was statistically significant (P<0.05); the distribution rate of Malek grade 1 and 2 in the observation group was higher than that of the control group, and grade 3 and 4 were lower than the control group,the difference was statistically significant (P<0.05); the incidence of complications in the observation group was 3.84%, which was lower than 11.53% in the control group,the difference was statistically significant (P<0.05).Conclusion ?Compared with metal bare metal stents, cerebrovascular drug-eluting stents have a lower incidence of in-stent restenosis, which can significantly improve the hemodynamics of patients with stenosis, with fewer complications, and high safety. It is worthy of clinical application.
本研究結(jié)果顯示,術(shù)后6個月觀察組支架內(nèi)再狹窄發(fā)生率為7.67%,低于對照組的21.15%,差異有統(tǒng)計學(xué)意義(P<0.05),腦血管藥物洗脫支架治療椎動脈狹窄術(shù)后支架內(nèi)再狹窄發(fā)生率低,該結(jié)論與趙同源[10]等研究結(jié)果基本一致。同時觀察組狹窄處峰值流速、狹窄處阻力指數(shù)、患側(cè)寰椎段阻力指數(shù)均低于對照組,差異有統(tǒng)計學(xué)意義(P<0.05),提示腦血管藥物洗脫支架治療椎動脈狹窄,對狹窄部位血流動力學(xué)改善更明顯,利于局部微循環(huán)的改變,進一步促進臨床癥狀的改善。同時觀察組Malek分級1級、2級分布率高于對照組,3級、4級低于對照組,差異有統(tǒng)計學(xué)意義(P<0.05),提示腦血管藥物洗脫支架治療效果更明顯,促進神經(jīng)功能缺損恢復(fù),顯著減輕腦缺血發(fā)生情況。此外,觀察組并發(fā)癥發(fā)生率為3.84%,低于對照組的11.53%,差異有統(tǒng)計學(xué)意義(P<0.05),表明腦血管藥物洗脫支架治療并發(fā)癥少,應(yīng)用安全可靠。
綜上所述,腦血管藥物洗脫支架治療椎動脈狹窄效果更顯著,支架內(nèi)再狹窄發(fā)生率低,且有助于改善患者神經(jīng)功能缺損和顱內(nèi)血流動力學(xué)指標(biāo),并發(fā)癥少且安全性高,具有臨床應(yīng)用的重要價值。
