Relation of Implantation Site to Placental Site

March 6, 2018 updated by: Ahmed Maged, Cairo University

Relation of Implantation Site to Placental Site With or Without Cesarean Section Scar

Trans vaginal ultrasound with a partially full bladder will be done at gestational age earlier than 10 weeks to assess the site of intrauterine gestational sac to the endometrial cavity and the distance between the implantation site and the internal cervical os . Doppler assessment of the retrochorionic blood flow at the area behind the maximum chorionic tissue to detect resistance index.
