Abstract:
Objective:To summarize the prenatal ultrasound characteristics of fetal malformations with amniotic band syndrome (ABS) in early pregnancy, in order to improve the ultrasound detection rate of this disease.Methods:Pregnant women who underwent systematic ultrasound screening of early pregnancy fetal malformations in Beijing Obstetrics and Gynecology Hospital from January 2017 to October 2023 were retrospectively collected. Twenty-three cases of early pregnancy ABS were collected and confirmed by ultrasound diagnosis and induced abortion results. Clinical data, images, and examination results of these cases were studied and the ultrasound characteristics of early pregnancy ABS were summarized.Results:In all 23 cases, adhesions between the intrauterine amniotic band and the affected parts of the fetus were found during ultrasonography, and the malformations in each case were different and closely related to the damage to different body surface parts of the fetus. Multiple fetal malformations accounted for 78% (18/23) and single cases accounted for only 22% (5/23). Among the 23 cases, 19 (83%) involved fetal limbs, 11 (48%) brains, 11 (48%) thoracic and abdominal walls, 10 (43%) spine, 5 (22%) faces, and 5 (22%) umbilical cords.23 (100%) patients were confirmed to have ABS after induction of labor, which was consistent with the ultrasound diagnosis, but 11 (48%) of them did not accurately describe fetal limb or facial abnormalities.Conclusions:The fetal malformation of ABS in the first trimester is closely related to the amniotic band, which has the characteristics of multiple properties, uniqueness, randomness and asymmetry. The most affected parts are the fetal limbs, brain, and body wall, and severe malformations are common.Prenatal ultrasound can provide suggestive diagnosis.
