Diagnostic Value of Traxnsvaginal Color Doppler Ultrasound for Ectopic Gestation Sac and Corpus Luteum Cyst

Objective:To probe into the contrastive study on ectopic gestation sac and corpus luteum cyst,so as to improve the early diagnostic accuracy.Method:The two-dimensional ultrasonic and Color Doppler examination in 60 patients with ectopic gestation sac and 74 ones with corpus luteum cyst were reviewed.Result:Small non-echo areas(echo of the small follicular) have been seen near 55.4%(41/74) of the corpus luteum cyst,but they have never been found in the ectopic gestation sac;The color Dopper flow signal which are the dot and short-bar shapes could be found near 95%(57/60) of the ectopic gestation sac wall;The ring like flow signal can be found in the surrounding 89.2%(66/74) of the corpus luteum cyst wall.By analyzing of the pulse Doppler spectrum,the resistance index of the corpus luteum cyst wall is lower than that of the ectopic gestation sac(P0.05).Conclusion:By estimation of the relationship between the adnexal cyst and the ovary,the flow signal of the ectopic gestation sac wall and the corpus luteum cyst wall were compared,and the color Doppler spectrum were reviewed.The early diagnostic accuracy of ectopic gestation sac and corpus luteum cyst can be improved by transvaginal color Doppler ultrasound.
