超声诊断及心血管造影在先天性心脏病介入封堵术中的联合应用

目的评价超声诊断及心血管造影在先天性心脏病(CHD)介入治疗中的联合应用价值。方法分析139例经超声心动图(UCG)检查确诊并成功进行介入封堵术的CHD患者,其中室间隔缺损(VSD)65例、动脉导管未闭(PDA)74例。介入术前均行心血管造影检查并测量VSD右室出口和PDA狭窄处最小直径;介入术后重复造影及超声检查评价封堵器位置、形态、有无残余分流等。结果超声检查及心血管造影均能明确诊断先天性心脏病,对其位置部位、形态均能良好显示。上述两种方法测量65例VSD缺损直径分别为(5.46±2.64)mm和(4.26±2.23)mm,测量74例PDA最窄处直径分别为(5.53±1.45)mm和(4.37±1.27)mm,两组差异均有统计学意义(P<0.05)。结论超声诊断对VSD及PDA术前病例筛选及术后疗效评评估更具优势,而在VSD和PDA介入封堵术中心血管造影对病变直径测量及封堵器选择更为可靠。

The combined application value of ultrasonography and cardioangiography in interventional treatment for patients with congenital heart disease

Objective To evaluate the combined application value of ultrasonography and cardioangiography in interventional treatment for congenital heart disease（CHD）.Methods 139 CHD patients checked and confirmed by echocardiography（UCG） received successful transcatheter.Among them,there were 65 cases of ventricular septal defect（VSD） closure and 74 cases of patent ductus arteriosus（PDA）.Minimum diameters of VSD and PDA were measured with ultrasonography and cardioangiography before and after interventional therapy for evaluation of occluder location,configuration and residual shunt.Results Ultrasonography and cardioangiography could clearly show the locations and configurations of VSD and PDA.The minimum diameters of VSD（n=65） measured by cardioangiography and uhrasonography was 5.46±2.64 mm and 4.26±2.23 mm respectively;The minimum diameters PDA（n=74） were 5.53±1.45 mm and 4.37±1.27 mm,respectively.There was significant difference between two groups（P 0.05）.Conclusion Ultrasonography diagnosis of VSD and PDA have more advantages in cases screening and postoperative evaluation,and cardioangiography are more reliable for measuring diameters and selection of occluders of VSD and PDA during interventional therapy.
