Results: Bleeding at the insertion point during amniocentesis did not significantly change the UARI (34% increase for Group 1 and 46.5% increase for Group 2, p=0.238), the MCARI (52% increase for Group 1 and 45% increase for Group 2, p=0.622), or the MCAPSV (37% increase for Group 1 and 49% increase for Group 2, p=0.199). UARI, MCARI, MCA PI, and MCAPSV were not significantly altered following amniocentesis in Groups 1 and 2. There was a significant increase in UAPI following amniocentesis only in Group 2. Abstract peak systolic velocity, the highest velocity was used. All of the invasive procedures and Doppler evaluation were performed by a single operator. The study was approved by the ethics and educational issues coordinating committee of the institution where the study was conducted. All of the patients signed written consent that their data could be used with appropriate ethical committee approval prior to genetic amniocentesis.
Conclusion:
