Neonatal subdural hematoma secondary to birth injury. Clinical analysis of 48 survivors.
In order to evaluate the treatment and prognosis of subdural hematoma in neonates, we analyzed 48 survivors in the 3-year period January 1979 to December 1981. Based on the CT findings, the hematomas were grouped into four types according to location: type I, localized around the posterior interhemispheral fissure (25 cases, 52%); type II, extending from the posterior interhemispheral fissure to the hemispheric convexity (5 cases, 10%); type III, extending from the incisura to the posterior fossa (15 cases, 31%); and type IV, subdural hematoma accompanied by intracerebral hemorrhage (3 cases, 7%). Intracranial pressure was measured via the anterior fontanel in 13 cases. In 10 cases of extensive hemorrhage, the pressure exceeded 200 mm H2O. The age of the patients was from 0 to 7 days. There were 36 mature (75%) and 12 premature (25%) infants. The mothers were primiparous in 27 cases (56%). Fetal presentation was cephalic in 38 cases (79%), in 10 of which (21%) suction delivery was performed, and breech in 11. The fundus oculi was examined in 32 cases. Retinal hemorrhage was noted in 12 cases; it did not correlate with the type of hematoma or the intracranial pressure. Operations were performed in 13 cases; 1 of type I, 4 of type II, 5 of type III, and 3 of type IV. Functional prognoses were found to be as follows: type I, normal 15, abnormal 4, undetermined 6; type II, normal 4, abnormal 1; type III, normal 13, abnormal 1, undetermined 1; type IV, normal 1, abnormal 2 cases.
