Abstract

Objective: To analyze the ultrasonic features of cesarean section scar and cervical pregnancies and to evaluate the diagnostic value of transvaginal color Doppler ultrasound for the diseases. Materials and Methods: Cases of cesarean scar and cervical pregnancy diagnosed and managed from 1995 to 2005 were included. Transvaginal color Doppler sonographic(TVS) findings, clinical treatments, pathologic results were followed up and analyzed. Results: Nine cesarean section scar pregnancies and five cervical pregnancies diagnosed with TVS were confirmed by surgery and pathological examination. All cases were classified into four subtypes according to their ultrasonic characteristics. Type I: gestational sac with embryo alive(5 cases). Type II: gestational sac with demise embryo(2 cases). Type III: like trophoblastic disease(4 cases). Type IV: villus degeneration(3 cases). Three cases undertook hysterectomy and two cases received conservative management in type I. Both cases of type II undertook hysterectomy. In type III, one underwent hysterectomy, villus was evacuated through cervical incision in one case and conservative management was applied in 2 cases. All cases of type IV had received conservative management. Conclusions: Transvaginal color Doppler ultrasound may give precise diagnosis for lower part of uterus pregnancies. The classifications according to the ultrasonographic features may direct the exact clinical therapy and to predict prognosis.
