蛛网膜下腔出血(ＳＡＨ)是新生儿颅内出血的常见类型,在新生儿缺氧缺血性脑病合并的颅内出血中,ＳＡＨ约占90%以上[1]。以往我们认为Ｂ超对ＳＡＨ的诊断阳性率很低[2,3]。近年来,我们在临床实践中发现ＳＡＨ在颅脑Ｂ超中有一定特异性,可为本病诊断提供间接依据。本文对14例缺氧 Subarachnoid hemorrhage (SAH) is a common type of intracranial hemorrhage in newborns, SAH accounts for more than 90% of intracranial hemorrhage in neonates with hypoxic ischemic encephalopathy [1]. In the past we believe that the diagnosis of SAH B-positive rate is very low [2,3]. In recent years, we found in clinical practice SAH in the brain B ultrasound has a certain specificity, can provide an indirect basis for the diagnosis of this disease. In this paper, 14 cases of hypoxia
