MALFORMATIONS AND INTRAUTERINE GROWTH RESTRICTION IN TWINNING

A CASE REPORT

Abstract

Twin pregnancies have higher fetal mortality and morbidity compared to singleton pregnancies, especially monochorionic pregnancies, as they are associated with a higher risk of malformations, fetal growth disorders and prematurity. The objective of the present work is a case report on diamniotic monochorionic twins associated with a selective growth restriction due to a malformation of the digestive system. The definitive diagnosis of tracheoesophageal fistula is established with the direct visualization of the fistulous path through esophagoscopy and/or tracheoscopy, radiological visualization by imaging methods, surgeries and autopsies, demonstrating a diagnostic difficulty, since the ultrasound does not have specific signs, being discovered only during childbirth. Therefore, the determination of chorionicity is fundamental for the adequate planning of prenatal and ultrasound follow-up, since it is directly related both to the increased risk of complications and to alterations exclusive to monochorionicity.
