彩色多普勒超声指标与瘢痕妊娠清宫术中出血量的相关研究

Correlation between Doppler ultrasound and the amount of bleeding in cesarean section scar pregnancy

目的 :探讨彩色多普勒超声在瘢痕妊娠(CSP)治疗中的临床价值。方法 :选取87例CSP孕妇,在子宫动脉栓塞术(UAE)后行清宫术,并依据术中出血量分为出血组(> 200 mL)26例和对照组(<200 mL)61例。比较2组UAE前后血流的RI、孕囊大小、子宫下段肌层厚度、子宫下段缺损面积及血流丰富程度。结果:2组一般资料未见明显差异,栓塞后孕囊周围血供明显减少,孕囊越大,子宫下段缺损面积越大,术中出血越多;子宫下段肌层厚度越薄,越易出血。结论:UAE能有效减少孕囊周边血供,超声指标可预测术中出血量。

Objective:To explore the clinical value of Doppler ultrasound in the management of interventional therapy for scar pregnancy. Methods:A total of 87 pregnancies with cesarean section pregnancy were enrolled,and uterine artery embolization was performed. Subsequently,the uterus was divided into two groups according to the amount of intraoperative blood loss. The bleeding group was more than 200 mL,and the control group was less than 200 mL. The flow resistance index before and after uterine artery embolization. The size of the gestational sac,the thickness of the lower uterine layer,and the defect area of the lower uterus were measured and recorded. The blood supply was observed and the changes of these parameters were analyzed.Results:There was no significant difference in the general information between the two groups. The blood supply around the gestational sac was significantly reduced after embolization. The larger the gestational sac and the larger the defect area of the lower uterus,the more intraoperative hemorrhage. The thinner the thickness of the lower uterine muscle layer,the more likely the bleeding. Conclusions:Uterine artery embolization can effectively reduce the blood supply around the scar pregnancy,ultrasound indicators can predict intraoperative blood loss.
