The Detection, Outcome, and Presentation of Twin-Twin Transfusion Syndrome in Monochorionic Diamniotic Twin Pregnancies Followed with a Protocol of Fortnightly Ultrasound Examination

<b><i>Background:</i></b> Evidence to support a fortnightly scan protocol for monochorionic diamniotic (MCDA) pregnancies detect twin-twin transfusion syndrome (TTTS) is scarce. Also, TTTS-related mortality in an unselected cohort not well documented. Finally, common knowledge suggests that more frequent follow-up may pick up the disease at milder stage, but little known on ultrasound findings before diagnosis. <b><i>Objectives:</i></b> We examine if from 16 weeks onward detects TTTS time. we document outcomes large of MCDA twins and within 14 days <b><i>Methods:</i></b> Retrospective 675 twin followed with onward. Timely detection was defined as fetal demise (stage V), ruptured membranes, or dilated cervix. compared diagnosis between stage I–II III–IV. <b><i>Results:</i></b> A total 82/675 (12%) developed TTTS, which 74/82 (90%) were detected In 8/82 (10%), diagnosed V: 5 2 after 26 weeks. Fetoscopic laser photocoagulation (FLP) placental anastomoses performed 48/82 (59%). The survival entire 105/164 (64%). contrast, FLP 77/96 (80%). 16/19 (84%) III–IV abnormal Doppler preceded TTTS. <b><i>Conclusions:</i></b> scheme scans 9 out ten Most V cases presented outside typical time window Survival rates underestimate have
