Abstract
Objective To investigate the clinical value of transvaginal color Doppler flow imaging(TV-CD-FI)in the differential diagnosis of unruptured tubal pregnancy and pregnant corpus luteum.Methods Sixty-seven cases of unruptured tubal pregnancy and 74 cases of intrauterine pregnancy complicating pregnant cor-pus luteum in the department of obstetrics and gynecology of this hospital during January 2015 were selected as the tubal pregnancy group and corpus luteum group respectively.The two groups received the preoperative TV-CDFI examination.Then the imaging characteristics and difference in the two groups were analyzed.Re-sults The hyperechoic rate in the tubal pregnancy group was 73.13%,which was significantly higher than 8.11% in the corpus luteum group,the difference had statistical significance(P<0.05).The main manifesta-tions in the tubal pregnancy group were heterogeneous mass type(61.19%),while which in the corpus luteum group was thick wall cyst type(79.73%),the difference had statistical significance(P<0.05).The ultrasonic blood flow characteristics in the tubal pregnancy group mainly were manifested by semi-ring,dot/line,which in the corpus luteum group were ring type,the difference had statistical significance(P<0.05);the peak flow rate of systolic artery blood flow(PSV)in the tubal pregnancy group was lower than that in the corpus luteum group,while the vascular resistance index(RI)was higher than that in the corpus luteum group,the difference was statistically significant(P<0.05).The sensitivity of TV-CDFI in the differential diagnosis of unruptured tubal pregnancy and pregnant corpus luteum was 95.52%,the specificity was 91.89%,the missed diagnosis rate was 4.48% and the misdiagnosis rate was 8.11%.Conclusion TV-CDFI for in the differential diagnosis of unruptured tubal pregnancy and pregnant corpus luteum has higher clinical practical value.关键词
