[摘要] 目的 探讨血管内超声指导导丝通过技术开通冠状动脉慢性闭塞性病变的临床疗效。方法 方便选取该院2015年1月—2017年1月所收治的120例行冠状动脉造影检查诊断为慢性完全闭塞病变(CTO)并行经皮冠脉介入治疗(PCI)的住院患者作为研究对象,将其随机分为研究组和对照组,各60例;研究组施以血管内超声(IVUS)指导导丝通过技术治疗,对照组未使用血管超声指导,对比两组临床效果。 结果 研究组经IVUS指导导丝通过技术治疗后,其支架植入的成功率为93.33%,比对照组71.67%明显偏高(P<0.05);且研究组患者的手术时间、造影剂用量以及曝光时间均比对照组患者明显优越,组间差异有统计学意义(P<0.05);经6个月随访表明,研究组并发症发生率为3.33%,比对照组患者36.67%明显偏低(P<0.05)。结论 血管内超声指导导丝通过技术开通冠状动脉慢性闭塞性病变的临床疗效显著,有助于提高PCI的即刻成功率,减少手术时间,促进患者康复。

[Abstract] Objective This paper tries to evaluate the clinical efficacy of intravascular ultrasound guided guidewire in chronic coronary artery occlusion. Methods 120 patients underwent coronary angiography for the diagnosis of chronic total occlusion (CTO) and percutaneous coronary intervention (PCI) in this hospital from January 2015 to January 2017 were conveniently selected as the research objects and were randomly divided into the study group and the control group, with 60 cases in each group; the study group was treated with intravascular ultrasound (IVUS) guiding wire through technical treatment, the control group did not use vascular ultrasound guidance, and then the clinical effect of two groups were compared. Results The study group by IVUS guiding wire through technical treatment after stent implantation, the success rate was 93.33%, significantly higher than the control group of 71.67%(P<0.05); and the patients in the study group, operation time, contrast agent dosage and exposure time were significantly superior than the control group, and the differences between groups were significant(P<0.05); after 6 months of follow-up, the incidence of complications was 3.33%, significantly lower than the control group of 36.67%(P<0.05). Conclusion The clinical curative effect of intravascular ultrasound guided by guidewire technology for chronic coronary artery total occlusion lesions in PCI can improve the immediate success rate, reduce the operation time, and promote the rehabilitation of patients.

冠状动脉慢性完全闭塞性病变(CTO)是指闭塞时大于3个月的病变,CTO病变约占全部冠状动脉造影确诊为冠状动脉粥样硬化性心脏病的30%以上[1-2]。目前接受经皮冠状动脉介入治疗(PCI)者不足8%,CTO病变相应手术成功率低,且术后再闭塞以及再狭窄的发生率较高。相关医学研究表明[3-4],导丝通过失败是临床上CTO病变介入治疗不成功的关键原因,在导丝通过过程中经常会进入至内膜下的假腔,造成导丝前进不畅,极易引发冠脉穿孔等各類型并发症。随着超声技术的不断发展,血管内超声指导(IVUS)技术已经被广泛应用于CTO病变的介入治疗,对于治疗冠状动脉慢性闭塞性病变的临床疗效显著[3,5]。该研究方便选取该院在2015年1月—2017年1月120例所收治的行冠状动脉造影检查诊断为慢性完全闭塞病变(CTO)并行经皮冠脉介入治疗(PCI)的住院患者作为研究对象,分别施以血管内超声(IVUS)指导导丝通过技术治疗以及未使用血管超声指导导丝治疗,对比二者的效果,现报道如下。endprint
