英文摘要 | Background: The purpose of this study was to assess the resistance index and pulsatile index of peritrophoblastic flow in early ectopic pregnancy and the correlatios of these to the serum β -human chorionic gonadotropin (β -HCG) concentration. Materials and Methods: Twenty-six women with confirmed ectopic pregnancy underwent transvaginal color Doppler sonography preoperatively to detect the ectopic mass and measure the resistance index and pulstile index of the peritrophoblastic flow. Serum β -HCG was measured simultaneously. Results: Peritrophoblastic flow was detected in 23 of the 26 cases;14 cases had a β -HCG conentration less than 800 mIU/ml. The mean resistance index was 0.41 ± 0.09 and the pulsatile index was 0.61 ± 0.22. The peak systolic velocity ranged from 6 to 60 cm/sec. Low-impedance flow is usually associated with ectopic pregnancy; however, three cases showed bizarre waveforms with reverse and/or absent end-diastolic flows. No significant correlation between the resistance index or pulsatile index and the serum β -HCG concentration was found. Conclusion: The peritrophoblastic flow of the majority of ectopic pregnancies can be detected even when the β -HCG concentration is less than 800 mIU/ml, Ectopic pregnancy may have unique bizarre waveforms. Low concentrations of β -HCG may be correlated with an active peritrophoblastic flow; the possibility of rupture in ectopic pregnancy should be taken into consideration. |
