Abstract:Objective To explore the detection results of the corpus luteum blood flow in pregnancy of unknown location (PUL) by transvaginal color doppler ultrasound and its prediction effect on pregnancy outcome. Methods A total of 120 PUL patients admitted to the West Campus of Qingdao Municipal Hospital from January 2014 to January 2017 were enrolled in the study. According to the pathological findings of the surgery, there were 58 cases of ectopic pregnancy group and 62 cases of intrauterine pregnancy group. In the intrauterine pregnancy group, 32 cases of premature pregnancy and 30 cases of premature intrauterine abortion were confirmed. The echo type and blood flow classification of the corpus luteum and the resistance index (RI), pulsatile index (PI) and peak systolic flow velocity (PSV) between the two groups were compared. The predictive value of Receiver operator characteristic curve (ROC) on ectopic pregnancy and intrauterine pregnancy abortion was analyzed. Results The blood classification of the intrauterine pregnancy group was significantly better than that of the ectopic pregnancy group, the difference was statistically significant (P < 0.05). The RI and PI of luteal blood flow in the intrauterine pregnancy group were lower than those in the ectopic pregnancy group, while the PSV in the ectopic pregnancy group was significantly higher than that in the ectopic pregnancy group (P < 0.05).The area of the luteal blood flow RI, PI, and PSV for predicting ectopic pregnancy was 0.884, 0.711, 0.867. The luteal blood flow RI of the patients with intrauterine early pregnancy was lower than patients with early pregnancy abortion, while the PSV was significantly higher than patients with early pregnancy abortion (P < 0.05). The area under the curve of RI and PSV for predicting intrauterine pregnancy abortion was 0.829 and 0.830 respectively. Conclusion Transvaginal color Doppler ultrasound can identify the pregnancy position of PUL patients as early as possible, and have higher predictive value for ectopic pregnancy and intrauterine pregnancy abortion.
