Abstract
To substantiate the clinical impression of an increased incidence of intracranial hemorrhage (ICH) in term and near-term infants with persistent pulmonary hypertension (PPH), a retrospective chart review of 35 affected patients was performed. ICH was diagnosed in 40 percent of the patients. Multiple regions of the brain were affected; in many patients, at more than one location. In addition, 43 percent of ICH victims had hemorrhages of the type associated with periventricular bleeding in preterm newborns. Of multiple obstetric and neonatal factors analyzed, many of which are identified risk factors for periventricular hemorrhage, only thrombocytopenia (p = 0.02) was significantly associated with ICH. We conclude that the risk of ICH in newborns with PPH is significant and warrants consideration by clinicians caring for this population. Risk factors (except thrombocytopenia) previously implicated in other types of neonatal ICH, particularly periventricular hemorrhage, do not significantly correlate with ICH in infants with PPH.
