Dengue is one of the most important mosquito-transmitted arboviral diseases of tropical and subtropical parts of the world. It is estimated that 100 million cases occur per year, and 2.5 billion people at risk. Hemorrhagic complications causing encephalopathy is a rare but fatal. We discuss the management of 5 uncommon cases of intracranial hemorrhage in dengue. High index of suspicion is required for early diagnosis.
Five of these patients with intracranial bleed were managed in neurosurgery unit. All the patients had deranged prothrombin time and thrombocytopenia. They were given platelet concentrates for correction of thrombocytopenia. All parameters and neurologic status were closely followed. Four of these patients had deterioration in neurologic status; 2 of them underwent surgery.
Two patients who underwent surgery had excellent outcome. One patient was managed conservatively with cerebral decongestants. Two patients with deep-seated bleed had very rapid deterioration and died.
High index of suspicion in dengue is required especially during convalescence in those patients who are disoriented and have altered sensorium. It should not be misinterpreted as fever delirium or toxic encephalopathy. It needs immediate attention and investigation. Timely diagnosis and intervention can thus save many precious lives.
登革热是世界热带和亚热带地区最重要的蚊媒虫媒病毒疾病之一。据估计,每年有1亿例病例发生,25亿人面临风险。导致脑病的出血性并发症虽罕见但致命。我们讨论5例登革热颅内出血罕见病例的治疗。早期诊断需要高度怀疑指数。
其中5例颅内出血患者在神经外科病房接受治疗。所有患者的凝血酶原时间均紊乱且血小板减少。他们接受了血小板浓缩物治疗以纠正血小板减少。密切监测所有参数和神经状态。其中4例患者神经状态恶化;2例接受了手术。
2例接受手术的患者预后良好。1例患者采用脑消肿剂保守治疗。2例深部出血患者病情迅速恶化并死亡。
对于登革热患者,尤其是在恢复期出现定向障碍和意识改变的患者,需要高度怀疑指数。不应将其误解为发热谵妄或中毒性脑病。需要立即关注和调查。及时诊断和干预因此可以挽救许多宝贵的生命。
