摘　　要：目的:分析心脏计算机断层扫描血管造影(CTA)同步左心房和食管三维成像技术在房颤射频消融术中的临床应用价值,以指导临床手术方案的制定。方法:选取医院收治的101例阵发性心房颤动患者临床资料,通过心脏CTA同步行左心房和食管三维成像技术与否,将其分为造影剂组(54例)和非造影剂组(47例)。对两组扫描及重建后的图像质量进行测量,主观评价患者的基本信息,对手术时间、X射线曝光时间、术后视觉模拟量表(VAS)评分以及术后食道损伤发生率等进行统计学分析。结果:造影剂组患者手术时间、X射线曝光时间及VAS评分均少于非造影剂组,两组比较差异有统计学意义(t=8.481,t=13.425,t=3.072;P<0.05)。术后造影剂组患者食道损伤率为1.9%,非造影剂组患者食道损伤率为14.9%,两组比较差异有统计学意义(x^(2)=4.208,P<0.05)。结论:心脏CTA数字化三维成像在一定程度上能够提高手术效率,缩短X射线曝光时间,减少食道损伤并发症的发生率,具有临床指导意义。Objective:To analyze the clinical application value of computed tomography angiography(CTA)synchronized with three-dimensional(3D)imaging technique on left atrial and esophageal in radiofrequency ablation of atrial fibrillation(AF),and to guide the formulation of clinically surgical plan.Methods:Clinical data of 101 patients with paroxysmal AF who admitted to hospital were selected.They were divided into the contrast agent group(n=54)and the non-contrast agent group(n=47)according to whether they underwent cardiac CTA synchronized with 3 D imaging technique on left atrial and esophageal.The image qualities after scanning and reconstruction of the images of two groups were measured,and the basic information of patients were subjectively evaluated,and operative time,X-ray exposure time,postoperative visual analogue scale(VAS)score and the incidence of postoperative esophageal injury were analyzed by using statistical method.Results:The operative time,X-ray exposure time and VAS score of contrast agent group were all lower than those of non-contrast agent group,and the differences of these indicators between two groups were statistically significant(t=8.481,t=13.425,t=3.072,P<0.05).After surgery,the incidence of esophageal injury was 1.9% in contrast agent group and that was 14.9% in non-contrast agent group,the difference of that between two groups was statistically significant(x^(2)=4.208,P<0.05).Conclusion:Cardiac CTA digital 3 D imaging can improve surgical efficiency to a certain extent,and can shorten X-ray exposure time,and reduce the incidence of complications of esophageal injury.It has guiding significance for clinical work.
