Effect of hysteromyoma uterine treated by uterine artery embolization with color Doppler ultrasound

Objective To evaluate the curative effect of hysteromyoma uterine treated by uterine artery embolization (UAE) with color Doppler ultrasound.Methods Seventeen patients with hysteromyoma uterine were examined by color Doppler ultrasound before and after uterine artery embolization wthin half year monthly,observing the size, morphology,internal echotexture and Doppler signal of the uter and its myoma,measuring their Doppler indices of uterine artery,peripheral and internal vascular in myoma.Results There was significant difference of the average volume of the uterus and its myoma between pre-operation and post-operation( 435.18 cm 3 vs 222.51 cm 3, 102.47 cm 3 vs 52.10 cm 3,respectively, P 0.01 ).The resistence index around myoma was higher than interior,and the resistence index of its uterine artery was lower than normal.Before the uterine artery embolization,the typical myoma was hypoechoic or isoechoic,had halo sign and the blood flow signal was richer at its peripheral than its internal.Three months after operation, the echo of myoma became smaller and smaller,then maintained stable, the echo of myoma changed from snow-like hyperecho to heremogeneous isoecho or hypoecho. No nonecho was seen,the halo sign dispeared and became ring strong echo which matched with the course of the uterine artery.The internal of myoma was no-blood-flow display after UAE,its periphery changed from no flow firstly to dot and short-bar flow signal .The clinic effect was judged by the decrease of menstrual and the total effectiveness was 88%.Conclusions UAE is promising method for hysteromyoma uterine with little invasion and good effect.
