Abbreviations: H, hemorrhage; IVH, intraventricular hemorrhage; WM, white matter.
aData are expressed as n (%). Extraaxial hemorrhage included subdural or subarachnoid hemorrhage.
bWM lesions were classified in (1) mild-moderate injury including focal lesions (periventricular, subcortical, punctate, or infarct) and (2) extensive lesions (extensive loss of gray-WM differentiation, infarctions, and bleeding).
cAll 12 infants had transverse sinus thrombosis (6/12 had also sigmoid sinus thrombosis).
d Three of 13 infants had only straight sinus thrombosis; 10/13 had cerebral internal vein and/or Galen vein thrombosis (8/10 also had straight sinus thrombosis).
