目的总结先天性心脏病室间隔缺损的超声诊断特点,评价彩色多普勒超声心动图对室缺的诊断价值。方法分析总结了50例室缺患者的二维超声心动图,运用彩色多普勒及脉冲或连续多普勒测定分流速度、跨隔压力及观察有无伴发其它畸形,筛选能否做介入封堵术。结果 50例室缺患者的检出率为100%,定位诊断符合率约88.4%,不符合的11.6%,9例经超声心动图筛选并监护下行心内微创介入封堵术,8例封堵成功。结论彩色多普勒超声心动图对室缺的定性、定位分型及大小定量可做出较全面准确的诊断,为临床提供可靠的治疗依据,是诊断室间最佳的无创性检查方法。
Objective To summarize the diagnostic characteristics of ventricular septal defect in congenital heart disease and evaluate the diagnostic value of color Doppler echocardiography in ventricular septal defect. Methods Two-dimensional echocardiography was analyzed in 50 patients with ventricular septal defect. The color Doppler and pulsed or continuous Doppler were used to determine the shunt velocity, trans-septal pressure and the presence or absence of other malformations. Blocking surgery. Results The detection rate of 50 cases with ventricular septal defect was 100%, the coincidence rate of positioning diagnosis was 88.4% and 11.6% did not meet, and 9 cases underwent echocardiography screening and monitoring with intracardiac minimally invasive interventional cardiopulmonary occlusion Blocking success. Conclusions Color Doppler echocardiography can provide a more comprehensive and accurate diagnosis of ventricular septal defect, its location, typing and size, so as to provide a reliable basis for clinical treatment. It is the best noninvasive diagnostic method for the diagnosis room.
