P05.01: Regional responses in middle cerebral artery in severely growth restricted fetuses: preliminary reports of postnatal follow up

in the assessment of uterine malformations and its contribution to operative management. Methods: Forty-four pre-menopausal patients with suspected uterine anomalies on 2D TVS were evaluated by 3D TVS, hysteroscopy, and if necessary by laparoscopy or MRI. Ultrasound volume of the uterus was obtained by free hand rotation of the probe on the longitudinal axis of the uterus. Three perpendicular planes were simultaneously shown on the screen and classification of the type of anomalies was effected on the coronal view of the uterus based on the outer shape and the angle of the fundal identation. This 3D TVS diagnosis was compared with the hysteroscopic and/or laparoscopic classification. Results: We correctly classified by 3D TVS 20 arcuate, 12 septate and 6 bicornuate uteri (concordance rate 86%). Using 3D ultrasound 4 septate uteri were classified by hysteroscopy as arcuate and 2 arcuate uteri as septate. Sensitivity for bicornuate uteri was 100%. Conclusions: 3D TVS allows accurate differentiation between uterine anomalies and is useful for a preoperative surgical planing.
