Death from cerebrospinal fluid shunt malfunction is a rare but tragic event. The authors describe seven children who when admitted were lethargic but arousable because of shunt failure. Sudden deterioration prompted unscheduled emergency shunt revision in each case. Two children subsequently died. Although neither the history nor the physical findings predicted this life-threatening shunt malfunction, obliteration of the perimesencephalic cistern was apparent on all preoperative computerized tomography (CT) scans. For reference, the scans of 43 other hydrocephalic children were drawn randomly from the hospital files and analyzed. It is concluded that CT evidence of obliteration of the perimesencephalic cistern is a useful warning of life-threatening shunt failure.
脑脊液分流器故障导致的死亡是一种罕见但悲惨的事件。作者描述了七名儿童，他们入院时因分流器故障而嗜睡但可唤醒。突发病情恶化促使对每例患儿进行了非计划的紧急分流器修复手术。两名儿童随后死亡。尽管病史和体格检查结果均未预示这种危及生命的分流器故障，但所有术前计算机断层扫描（CT）均显示中脑周围脑池消失。作为对照，从医院病历中随机抽取并分析了其他43例脑积水患儿的扫描结果。得出的结论是，中脑周围脑池消失的CT证据是危及生命的分流器故障的有用警示信号。
