[摘要] 目的 探討血管內超聲指導導絲通過技術開通冠狀動脈慢性閉塞性病變的臨床療效。方法 方便選取該院2015年1月—2017年1月所收治的120例行冠狀動脈造影檢查診斷為慢性完全閉塞病變(CTO)并行經皮冠脈介入治療(PCI)的住院患者作為研究對象,將其隨機分為研究組和對照組,各60例;研究組施以血管內超聲(IVUS)指導導絲通過技術治療,對照組未使用血管超聲指導,對比兩組臨床效果。 結果 研究組經IVUS指導導絲通過技術治療后,其支架植入的成功率為93.33%,比對照組71.67%明顯偏高(P<0.05);且研究組患者的手術時間、造影劑用量以及曝光時間均比對照組患者明顯優越,組間差異有統計學意義(P<0.05);經6個月隨訪表明,研究組并發癥發生率為3.33%,比對照組患者36.67%明顯偏低(P<0.05)。結論 血管內超聲指導導絲通過技術開通冠狀動脈慢性閉塞性病變的臨床療效顯著,有助于提高PCI的即刻成功率,減少手術時間,促進患者康復。

[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.

冠狀動脈慢性完全閉塞性病變(CTO)是指閉塞時大于3個月的病變,CTO病變約占全部冠狀動脈造影確診為冠狀動脈粥樣硬化性心臟病的30%以上[1-2]。目前接受經皮冠狀動脈介入治療(PCI)者不足8%,CTO病變相應手術成功率低,且術后再閉塞以及再狹窄的發生率較高。相關醫學研究表明[3-4],導絲通過失敗是臨床上CTO病變介入治療不成功的關鍵原因,在導絲通過過程中經常會進入至內膜下的假腔,造成導絲前進不暢,極易引發冠脈穿孔等各類型并發癥。隨著超聲技術的不斷發展,血管內超聲指導(IVUS)技術已經被廣泛應用于CTO病變的介入治療,對于治療冠狀動脈慢性閉塞性病變的臨床療效顯著[3,5]。該研究方便選取該院在2015年1月—2017年1月120例所收治的行冠狀動脈造影檢查診斷為慢性完全閉塞病變(CTO)并行經皮冠脈介入治療(PCI)的住院患者作為研究對象,分別施以血管內超聲(IVUS)指導導絲通過技術治療以及未使用血管超聲指導導絲治療,對比二者的效果,現報道如下。endprint
