| Objective Discussion the ultrasonographic features of the cornual pregnancy and the interstitial tubal pregnancy and their HCG level relations.Methods Collected from July2010to February2012, the Second Clinical Hospital of Shanxi Medical University hospital diagnosed58cases of patients by ultrasound with interstitial cornual pregnancy and tubal pregnancy,determinate their β-HCG level,and according to ultrasound results, analyz included not only the thickness of muscular layer around the gestation sac and the connection with the cavity of the uterus, determination of the gestational sac (mass) of the peripheral nutrient artery blood flow spectrum, but also the rate of accuracy and misdiagnosis.Results Serum β-HCG level of cornual pregnancy patients (9000.2±7503.8)mIu/Lwas higher than in interstitial tubal pregnancy (4080.1±3935.9) mIu/L (P<0.05). Cornual pregnancy sac (mass) of peripheral muscle layer (6.02±1.69) mm thickness and the cavity of uterus was larger than interstitial tubal pregnancy group (2.07±0.86) mm (P<0.05). The peak systolic velocity (PSV)(0.39±0.19) m/sand the end diastolic velocity (EDV)(0.14±0.11) m/swere lower but resistance index (RI)(0.58±0.18) higher in cornual pregnancy patients than in interstitial tubal pregnancy (0.46±0.17),(0.44±0.17) m/s,(0.24±0.12) m/s(P<0.05) in color Doppler hemodynamic parameters. Transabdominal ultrasound for cornual pregnancydiagnosis coincidence rate is46.5%, in interstitial tubal pregnancy is60.3%. Transabdominal scan (TAS) and transvaginal scan (TVS) for cornual pregnancy diagnosis coincidence rate is90.9%, interstitial tubal pregnancy diagnosis coincidence rate is about87.9%Conclusion (1)Ultrasonic examination to determine the gestational sac with the uterine cavity is communicated, the rate of pregnancy sac surrounding the availability of complete muscle layer and encases muscular layer thickness, combined with the gestational sac (mass) peripheral hemodynamic parameters RI, PSV and EDV were measured, can further improve the accuracy of ultrasound for early diagnosis, differential uterine horn pregnancy and interstitial tubal pregnancy important basis.(2) The combination of ultrasound and the serum HCG value can increased the cornual pregnancy and interstitial tubal pregnancy diagnosis rate.(3) Transabdominal combined transvaginal ultrasound can significantly improve the cornual pregnancy and interstitial tubal pregnancy diagnosis rate. |
