Abstract: 240 patients with suspected ectopic pregnancy were selected as the subjects. They were given transabdominal and transvaginal color ultrasound examination. The pathological examination was taken as control, the diagnostic value of transabdominal and transvaginal color ultrasound and their combination for ectopic pregnancy was analyzed. The results showed that the detection rate of ultrasonic signs of ectopic pregnancy such as pseudopregnancy sac, embryo bud, fetal heart beat, accessory mass and pelvic effusion in the transabdominal combined with transvaginal colour ultrasound was significantly higher than that in the transvaginal ultrasound, the detection rate of ultrasonic signs of ectopic pregnancy such as pseudopregnancy sac, embryo bud, fetal heart beat, accessory mass and pelvic effusion in the transvaginal colour ultrasound was significantly higher than that in the transabdominal colour ultrasound (P<0.05). In the sensitivity, specificity and accuracy of the diagnosis of ectopic pregnancy, the transabdominal color ultrasound was 77.38%, 63.89%, 73.33%, the transvaginal color ultrasound was 88.10%, 80.56%, 85.83%, the transabdominal combined transvaginal color ultrasound was 95.24%, 833 94.44%, 95.00%, the transabdominal combined transvaginal color ultrasound was significantly higher than the transabdominal or transvaginal color ultrasound (P<0.05). This study confirms that, compared with transabdominal or transvaginal colour ultrasound, transabdominal combined with transvaginal colour ultrasound can improve the display rate of ultrasound signs of ectopic pregnancy, and it is helpful to improve the diagnostic value.
