The aim was to investigate whether dexmedetomidine had a toxic effect on cerebral neurons when it was administered centrally into the cerebrospinal fluid by the intracisternal route. ⋯ In conclusion, dexmedetomidine had a toxic effect on cerebral neurons when it was administered centrally into the cerebrospinal fluid by the intracisternal route.

We describe a patient presented with sequential events of hemifacial spasm, cerebral infarction and fatal subarachnoid hemorrhage. All of them are seemingly separate entities. Radiological examination revealed that the cause was vertebrobasilar dolichoectasia (VBD) coexisting with a giant saccular aneurysm of basilar artery. ⋯ The condition is very rare and its progression may result in compression of brainstem and cranial nerves, ischemic and/or hemorrhagic stroke. The treatment of such condition is difficult and further research on the risk stratification of VBD for predicting stroke. Close monitoring and aggressive surgical interventions might be needed for high-risk patients.

To describe a reconstructive technique using single stent for wide-necked aneurysms. ⋯ The stent-jail technique represents an efficacious adjuvant technique to assist coiling of selected wide-necked cerebral aneurysms. This technique is particularly helpful for wide-necked aneurysms.

To raise the awareness of the appropriate management of unusual clinical presentation of cervical disc herniation. ⋯ Brown-Sequard syndrome is a rare presentation of cervical disc herniation but accurate diagnosis, and early anterior spinal cord decompression lead to complete recovery of these cases.

Burr-hole craniostomy is the most efficient and safe choice for surgical drainage of chronic subdural hematoma (CSDH). Although the twist-drill drainage is also relatively safe and time-saving, it carries the risk of inadequate drainage, brain penetration and hematoma formation. Our modified technique helps in avoiding bleeding and brain penetration. ⋯ Our modified technique of twist drill drainage is inexpensive, simple, safe and effective alternative technique in the treatment of CSDH.
