Real-time ultrasound studies of the head were performed on 96 infants weighing 1500 g or less. This population represented all such infants admitted within the first 72 hours of life to a neonatal intensive care unit over a 9-month period. Intracranial subependymal/intraventricular hemorrhage occurred in 22 (23%) of the infants. Of these 13 (59%) developed ventricular enlargement. Four other infants, in whom hemorrhage was not identified, also developed ventricular enlargement. When it occurred, the ventricular enlargement developed within 2 weeks of the hemorrhage in 77% of cases. It reached its maximum size within 2 weeks in 65% of cases. In 9 of 16 cases the maximal ventricular enlargement was categorized as mild. Spontaneous arrest or resolution of the ventriculomegaly occurred in all but two cases, who required shunting. Clot resolution was slow. It was complete at 3 weeks in only 5 of 18 cases.
对96名体重1500克及以下的婴儿进行了头部实时超声检查。该群体涵盖了在9个月期间出生后72小时内入住新生儿重症监护病房的所有此类婴儿。22名（23%）婴儿发生了颅内室管膜下/脑室内出血。其中13名（59%）出现了脑室扩大。另外4名未发现出血的婴儿也出现了脑室扩大。脑室扩大发生时，77%的病例在出血后2周内出现，65%的病例在2周内达到最大尺寸。16例中有9例最大脑室扩大被归类为轻度。除2例需要分流的病例外，所有病例的脑室扩大均自发停止或消退。血凝块溶解缓慢，18例中只有5例在3周时完全溶解。
