ObjectiveTo observe and analyze the effect of color doppler ultrasonography (CDU) in uterine arterial embolization (UAE).Methods160 cases of patients with uterine fibroid were selected in this study. CDU were performed on all patients before UAE as well as 5-9 days and 3-6 months after UAE, so as to observe the shape, size and ultrasonogram of the uterus and uterine fibroid, and the blood flow changes of the uterine fibroid. In addition, analysis was carried out on the improvement of the clinical symptoms 3 months to 6 months after UAE.Results5-9 days and 3-6 months after UAE, the blood flow of uterine fibroid was significantly reduced or even disappeared, with P <0.05; according to the observation carried out 3-6 months after UAE, irregular menstruation and uterine fibroid compression were significantly relieved; the uterine size and the uterine fibroid volume were significantly decreased;high-level echo was generated inside of the uterine fibroid, which was then gradually reduced into slightly higher echo, equal echo and low echo. High-level echo was found around the uterine fibroid.ConclusionIt is safe and reliable for the patients with symptomatic uterine fibroid to take UAE. The application of CDU can also provide a good basis and has great significance.
