BackgroundCongenital limb malformations are rare, and their perinatal outcomes are not well described. This study analyzed the perinatal outcomes of infants with congenital limb malformations.MethodsAll infants with congenital limb malformations who underwent prenatal assessment and delivery at our tertiary referral center from 2004 through 2017 were retrospectively identified. Neonatal outcome parameters were assessed, and the predictors of worse perinatal outcomes were determined.ResultsOne hundred twenty-four cases of congenital limb malformations were identified, of which 104 (83.9%) were analyzed. The upper limb was affected in 15 patients (14.4%), the lower limb in 49 (47.1%), and both limbs in 40 (38.5%) patients. A fetal syndrome was identified in 66 patients (63.5%); clubfoot and longitudinal reduction defects were the most frequent malformations. In total, 38 patients (36.5%) underwent termination, seven (6.7%) had stillbirth, and 59 (56.7%) had live-born delivery. Rates of preterm delivery and transfer to the Neonatal Intensive Care Unit were 42.4 and 25.4%, respectively. Localization of the malformation was a determinant of perinatal outcome (P=.006) and preterm delivery (P=.046).ConclusionsCongenital limb malformations frequently occur bilaterally and are associated with poor perinatal outcomes, including high rates of stillbirth and preterm delivery. Multidisciplinary care and referral to a perinatal center are warranted.
