目的探讨彩色超声对法洛四联征患者治疗前后心脏形态学及心功能的诊断价值,为预后判断提供参考。方法法洛四联症患者60例进行介入治疗,治疗前后采用彩色多普勒超声诊断仪进行心脏形态学及心功能诊断。结果 RVOT、PA、RI、Vmax和PGmax介入术前与介入术后是有显著性差异的(P<0.05),其中RVOT、Vmax以及PGmax的介入术后4个月与介入术后10d、之间也有显著性差异(P<0.05);LV介入术前与介入术后10d无显著性差异。介入术后4个月的RV与介入术后10d有显著性差异(P<0.05)。结论彩色多普勒超声用于法洛四联症的诊断具有敏感性强、无创、方法简便及可重复性等优点,能以多种指标反应法洛四联症治疗前后心脏形态学及心功能变化,有利于预后判断,值得推广应用。
Objective To investigate the value of color ultrasound in the diagnosis of cardiac morphological and cardiac function in patients with tetralogy of Fallot before and after treatment, and to provide a reference for the prognosis. Methods Sixty patients with tetralogy of Fallot were involved in the interventional therapy. Before and after treatment, color Doppler ultrasound was used to diagnose heart morphology and cardiac function. Results RVOT, PA, RI, Vmax and PGmax were significantly different between preoperative and postoperative interventions (P <0.05). There were significant differences between RVOT, Vmax and PGmax 4 months after PCI and 10 days after PCI There was also a significant difference (P <0.05); LV intervention before surgery and 10d after intervention there was no significant difference. The RV at 4 months after PCI was significantly different from that at 10 days after PCI (P <0.05). Conclusion The color Doppler ultrasound is used in the diagnosis of tetralogy of Fallot with the advantages of high sensitivity, non-invasiveness, simple and reproducible method, and can reflect cardiac morphological and cardiac function before and after treatment with tetralogy of Fallot Changes, is conducive to prognosis, it is worth promoting application.
