目的探讨静脉滴注缩宫素对子宫肌瘤患者超声检查的影响。方法对收治的87例子宫肌瘤患者进行多普勒超声检查,分析静脉滴注缩宫素前后平均血流速度(Vm)、收缩期峰值速度(PSV)、阻力指数(RI)、动脉血流量、血管管径的变化。结果静脉滴注缩宫素后,子宫肌瘤周围及内部供血大动脉Vm、PSV、血流量、血管管径均显著降低,而RI明显增大,与滴注前差异有统计学意义(P<0.05)。结论静脉滴注缩宫素可以减少肌瘤血供,使超声血流信号参数发生改变,临床检查时要综合分析,避免发生误诊、漏诊。
Objective To investigate the effect of oxytocin intravenous infusion on uterine fibroids in patients with ultrasound examination. Methods Eighty-seven patients with uterine fibroids underwent Doppler echocardiography. The mean velocity (Vm), peak systolic velocity (PSV), resistance index (RI), arterial blood flow Vascular diameter changes. Results After intravenous infusion of oxytocin, the Vm, PSV, blood flow and blood vessel diameter of peripheral artery and internal artery of uterine fibroids were significantly decreased, while RI significantly increased, which was significantly different from that before instillation (P <0.05 ). Conclusion Intrauterine injection of oxytocin can reduce the blood supply of fibroids and make the parameters of ultrasonic blood flow change. Comprehensive analysis should be done in clinical examination to avoid misdiagnosis and missed diagnosis.
