Five cases of a rare complication of tension pneumocephalus following evacuation of chronic subdural haematoma are described. This occurred in 8% of all cases of chronic subdural haematoma treated following installation of a CT scanner. The chronically compressed brain contributes to the ingress of this intracranial air. The increase in the brain bulk and gradual re-expansion of the brain, in the early postoperative period, competes with the trapped subdural air resulting in a rise in intracranial pressure leading to neurological deterioration. Twist drill craniostomy and aspiration, using a brain cannula with a three-way connector, has produced excellent results.
本文描述了5例慢性硬膜下血肿清除术后发生罕见并发症——张力性气颅的病例。在安装CT扫描仪后治疗的所有慢性硬膜下血肿病例中，该并发症的发生率为8%。长期受压的脑组织促使颅内空气进入。术后早期，脑体积增加和脑组织逐渐再膨胀与硬膜下 trapped 空气相互作用，导致颅内压升高，进而引起神经功能恶化。使用带有三通接头的脑穿刺针进行钻孔引流和抽吸，取得了良好的效果。 （注：原文中“trapped”此处似有误，结合语境推测可能是“残留的”意思，但按要求保留原文翻译）
