Abstract

The present prospective study was undertaken to evaluate whether blood flow changes occur at the level of the uterine arteries due the performance of a cervical cerclage. Twenty-one patients were enrolled into this study. Patients were all between 11 and 16 weeks of gestation. All patients underwent a cervical cerclage under general anesthesia. Blood flow measurements were performed before the anesthesia, during the anesthesia and before the cerclage placement and after the performance of the suture. Measurements were performed with a continuous wave (CW) Doppler (Flo-link 400 Obstetric blood flow analyzer, Rimed Ltd., Israel), with a transvaginal 4 MHz transducer linked to a 286 computer. The examinations were performed vaginally, by placing the probe laterally to the uterine cervix and locating the uterine artery by its characteristic sound and the typical waveform on the computer screen. The present study has shown a decrease in the S/D ratio immediately after the initiation of the anesthesia. An additional decrease is shown 10 minutes after the placement of the cerclage suture.
