Abstract:Objective To investigate the clinical effects of balloon-stent kissing technique(BSKT)versus reverse crush technique in the treatment of coronary artery bifurcation.? Methods A total of 240 patients with coronary artery bifurcation were selected from January 2015 to December 2015 and were randomly divided into control group treated with reverse crush technique and study group treated with BSKT (n=120, each). The surgical indicators, coronary angiography findings and complications were compared between two groups. Results The operative time［(57.8±16.2)min vs (81.5±19.6)min], X-ray exposure time［(36.5±11.9)min vs (59.2±15.6)min], dosage of balloon(2.5±0.8 vs 1.6±0.4) and contrast medium［(179±18)ml vs (215±36)ml] in study group were significantly lower than those in control group (all P<0.05). There was no significant difference in the success rate of kissing balloon (100% vs 100%, P＞0.05). After treatment, the rates of diameter stenosis and restenosis of vascular, late lumen loss were significantly lower than those in control group(all P<0.05). There was no significant difference in the incidence of complications such as angina pectoris, myocardial infarction and sudden death (all P>0.05).? Conclusion Compared with reverse crush technique, BSKT can increase the clinical effect and reduce the risk of restenosis in treatment of patients with coronary artery bifurcation.
