目的探讨食管超声心动图在经胸小切口房间隔缺损封堵术中的应用效果。方法选择2013年1月至2015年12月进行经胸小切口房间隔缺损封堵术的患者68例,根据术中不同诊断监测方法随机分为观察组和对照组各34例,将两组患者手术时间以及手术封堵成功率进行统计并对比。结果对照组患者手术时间为(40.15±6.55)min,观察组为(30.24±6.65)min,观察组患者手术时间明显短于对照组,具有统计学意义(T=7.51,P<0.01)。对照组患者封堵成功率为82.35%,观察组为99.48%,观察组成功率优于对照组,差异具有统计学意义(χ~2=22.22,P<0.01)。结论经食管超声心动图相比于经胸超声心动图,能更准确的显示术者缺损的位置、大小等相关信息,提高了手术封堵成功率,缩短了手术时间。
Objective To investigate the effect of esophageal echocardiography in the closure of atrial septal defect with transthoracic incision. Methods Sixty-eight patients undergoing transcatheter closure of atrial septal defect using mini-incision from January 2013 to December 2015 were randomly divided into observation group (34 cases) and control group (34 cases) according to different diagnostic methods. The patients in both groups Surgical time and surgical closure success rate statistics and comparison. Results The operation time of the control group was (40.15 ± 6.55) min and that of the observation group was (30.24 ± 6.65) min. The operation time of the observation group was significantly shorter than that of the control group (T = 7.51, P <0.01). In the control group, the successful rate of occlusion was 82.35% and that of the observation group was 99.48%. The success rate of the observation group was superior to that of the control group. The difference was statistically significant (χ ~ 2 = 22.22, P <0.01). Conclusion Compared with transthoracic echocardiography, transesophageal echocardiography can more accurately show the location, size and other related information of the defect, which can improve the success rate of operation occlusion and shorten the operation time.
