Subdural hemorrhage (SDH) in infants is commonly associated with nonaccidental trauma and “shaken baby syndrome,” and some reports suggest that SDH may appear in susceptible infants who have suffered apnea or significant hypoxia. Although generally asymptomatic, SDH related to birth trauma has also been reported to be common. Kelly and colleagues sought to determine the true incidence of SDH in infancy by looking at pre- and postoperative infants who have undergone a repair of congenital heart disease (CHD). In addition, the authors sought an association between the development of SDH and the presence of hypoxia.
The authors found that asymptomatic SDH was common in infants with CHD at a rate similar to those without CHD. These SDHs were typically small and resolved within three months of birth. The authors were unable to demonstrate any association between hypoxia and SDH in this cohort. However, the ability to generalize these results is limited due to the nature of the selected patient population.
