The function of the circle of Willis, an arterial polygon, is to protect the brain from ischemia. The aim of this study is to define the structural characteristics of the circle of Willis within the Turkish adult population, along with variations and arteries involved in the measurement of diameters and lengths on cadavers. ⋯ Advances in radiological methods which provide images of cerebral vessels and the development of cerebrovascular surgery have increased the importance of the circle of Willis in neurosurgery and neurology. The structure of the circle of Willis is of great importance in occlusive cerebrovascular diseases and cerebrovascular surgery.

Decompressive hemicraniectomy for a malignant middle cerebral artery infarct can be a life-saving surgical treatment. We aimed to investigate the surgical treatment results in cases that underwent decompressive hemicraniectomy for a malignant middle cerebral artery infarct in this study. ⋯ Decompressive hemicraniectomy in malignant middle cerebral artery infarct can be a life-saving procedure but is not useful in cases with a Glasgow coma scale score of 7 and below.

To evaluate the effects of NMDA receptor antagonist memantine and pancaspase inhibitor Q-VD-Oph in combination or alone in experimental spinal cord injury. ⋯ Combined use of memantine and Q-VD-OPh provides better histological and clinical results. The combined inhibition of the two major pathways, necrosis and apoptosis, needs to be further assessed with in-vivo or in-vitro studies.

Insular gliomas have traditionally been approached through variations of large frontotemporal craniotomies exposing much of the Sylvian fissure. Due to the importance of many structures exposed by such an approach, a less-invasive approach to these lesions is a viable alternative for resection. We present the technique and results of our keyhole transsylvian approach to remove infiltrating insular tumors. ⋯ Localized insular gliomas can be effectively removed through a minimally invasive approach without increasing the risk of neurological morbidity. This minimizes manipulation of uninvolved, potentially eloquent cortices, and minimizes damage to the overlying soft tissue.

To observe the outcome of burr hole evacuation of extradural hematoma (EDH) in mass head injury. ⋯ As EDH is potentially fatal lesion, evacuation of EDH through a single burr hole has good outcome with less chances of recurrence and complications in mass head injured patients as seen with earthquakes.
