      ULTRASOUND DIAGNOSIS OF DUODENAL OBSTRUCTION – KEY POINTS AND PITFALLS (Abstract): Prenatal ultrasound is able to detect a wide range of abnormalities of the gastrointestinal tract. Diagnostic suspicion of such anomalies should be regarded with caution, because there is a great amount of normal ultrasound images of the segments of the digestive system, some of them being easily confused with pathological aspects. Duodenal atresia and stenosis are between the most common causes of fetal bowel obstruction. The prevalence of duodenal atresia is 1:5000 to 1:10000 live births. It is associated in 30% of cases with Down syndrome, but also with other bowel atresias, cardiac malformations and VACTERL syndome. Prenatal ultrasound diagnosis of duodenal stenosis and atresia is based on identification of the polyhydramnios associated with the image of the “double bubble” in the upper abdomen of the fetus. For the correct use of the term “double bubble” the connection between the two structures containing liquid must be proven. If this connection cannot be viewed, other possible diagnoses must be taken into consideration.
Key words: DOUBLE BUBBLE, PRENATAL, ULTRASOUND, DUODENAL ATRESIA, STENOSIS
