Abstract
Placenta increta is a rare event in pregnancy, but is associated with serious maternal morbidity and mortality due to life threatening hemorrhage. The incidence has increased due to high Cesarean rates. We describe a case of placenta previa increta in a dichorionic twin pregnancy, which was successfully treated conservatively, to discuss the role of ultrasound, especially 3D VCI and TUI, for diagnosis and conservative management in similar cases. A GE Voluson Expert 730 ultrasound system which provides both conventional 2D imaging and 3D volume acquisitions using VCI and TUI was used for diagnosis and management in a case of placenta increta in a dichorionic twin pregnancy in which the placenta previa increta of the first fetus was left in situ and the other placenta was removed. The 3D VCI provided superior resolution of the anterior wall of the uterus, delineating the myometrial thickness in the area of the placental implantation site. With superior image quality, the 3D VCI technique facilitates the evaluation of the myometrial thickness and the depth of placental invasion due to significantly improved enhancement of the contrast and differentiation between various tissues compared to the 2D scan. We describe for the first time the application of 3D VCI and TUI for the visualization of the depth of placental invasion in such a case. Preoperative ultrasound diagnosis allows appropriate preoperative preparations and the decision to leave the placenta untouched to avoid a probable fatal outcome for the patient.
