Abstract:
Objective To observe the effect of intravascular ultrasound (IVUS) in the interventional treatment of chroinc total occlusion (CTO).
Methods A total of 72 CTO patients admitted to The Second Affiliated Hospital of Zhengzhou University from August of 2015 to March of 2017 were randomly divided into control group and experimental group, 36 patients in each group. The control group received PCI under the guidance of coronary angiography, and the experimental group received ivus-guided PCI. The surgical success rate, the incidence of intraoperative complications and the incidence of postoperative MACE were compared between the two groups.
Results The operation success rate of the control group (75.50%) was lower than that of the experimental group (94.44%), and the difference was statistically significant (P<0.05). The complication rate of the experimental group (8.33%) was lower than that of the control group (27.78%), and the difference was statistically significant (P<0.05). The incidence of postoperative MACE in the experimental group (5.56%) was lower than that in the control group (22.22%), and the difference was statistically significant (P<0.05).
Conclusion The IVUS has a good application effect in the interventional treatment of CTO patients, which can effectively improve the success rate of surgery, reduce the incidence of intraoperative complications and postoperative MACE, and has clinical promotion value.
