In a control group an intracranial bruit (ICB) was heard in 4 of 13 children aged between 4 months and 3 years, but in none of 43 younger infants between the ages of one day and 4 months. In a group of 70 infants with cardiac murmurs of intensity grade III/VI or more, 19 of 30 aged between 4 months and 3 years had an ICB, compared with 4 of 40 younger infants aged between one day and 4 months (P less than 0.0005). It is concluded that in infants under the age of 4 months, even in the presence of a loud cardiac murmur, an ICB is rarely heard. The presence of an ICB, with or without signs of cardiac failure, strongly suggests an intracranial arteriovenous fistula.
在一个对照组中，13名年龄在4个月至3岁之间的儿童中有4名听到颅内杂音（ICB），但在43名年龄在1天至4个月之间的小婴儿中均未听到。在一组70名强度为III/VI级或以上心脏杂音的婴儿中，30名年龄在4个月至3岁之间的婴儿中有19名有颅内杂音，而40名年龄在1天至4个月之间的小婴儿中有4名有颅内杂音（P小于0.0005）。得出的结论是，在4个月以下的婴儿中，即使存在响亮的心脏杂音，也很少听到颅内杂音。颅内杂音的出现，无论有无心力衰竭迹象，都强烈提示颅内动静脉瘘。
