Removal of clots in subarachnoid space could reduce the vasospasm after subarachnoid hemorrhage.
Cerebral vasospasm after subarachnoid hemorrhage (SAH) is a major cause of morbidity and mortality. We studied the effects of clot removal on multiple outcome variables following the clipping of ruptured anterior communicating aneurysms. ⋯ Fenestration of the lamina terminalis and removal of cisternal clots significantly decreased the incidence of post-SAH hydrocephalus and was associated with better outcomes in our series.

Computed tomography after decompressive craniectomy for head injury.
New findings (NF) on postoperative CTs are -occasionally found in patients who undergo surgery for traumatic brain injury (TBI). We conducted a retrospective -registry-based review of the care of 102 patients who underwent decompressive craniectomy (DC) for TBI to investigate the prognostic factors of new findings on CT early after -surgery. Of the 102 patients, the mean age was 50 years and 69.6 % were male. ⋯ The univariate analysis showed that a GCS score ≤8 (P = 0.012) and the absence of a basal cistern (P = 0.012) were significantly associated with NF on postoperative CT. The logistic regression analysis demonstrated that the GCS score ≤8 (P = 0.041; OR, 3.0; 95 % CI, 1.048-8.517) was the only significant factor. TBI patients with a low GCS score who underwent DC should undergo additional CT evaluations immediately after surgery.

Gamma Knife radiosurgery for the management of intracranial dural arteriovenous fistulas.
This report presents our 15-year experience with Gamma Knife radiosurgery (GKS) for the treatment of 321 patients with dural arteriovenous fistulas (DAVFs) in different locations. ⋯ GKS is a safe, effective treatment for DAVFs. It provides a minimally invasive therapeutic option for patients who harbor less-aggressive DAVFs but who suffer from intolerable clinical symptoms. For some aggressive DAVFs with extensive venous hypertension or hemorrhage, multimodal treatment with combined embolization or surgery is necessary.

Early cerebral circulation disturbance in patients suffering from different types of severe traumatic brain injury: a xenon CT and perfusion CT study.
Traumatic brain injury (TBI) is widely known to cause dynamic changes in cerebral blood flow (CBF). In particular, secondary brain insults have been reported to decrease CBF. The purpose of this study was to clarify the cerebral circulation in different types of TBI. ⋯ Moderate hypothermia therapy, which decreases CBF, the cerebral metabolic rate oxygen consumption (CMRO2), and intracranial pressure might be effective against the types of TBI accompanied by cerebral circulation disturbance. We have to use all possible measures including hypothermia therapy to treat severe TBI patients according to the type of TBI that they have suffered.

Intra-operative transdural electric stimulation in awake patient: target refining for motor cortex stimulation.
Most authors perform the implantation of epidural electrodes for motor cortex stimulation (MCS) under general anesthesia, using navigation merely based on anatomic landmarks or in combination with intra-operative sensory evoked potentials (SEP) for functional localization. However, intra-operative SEP can only provide the localization of central sulcus in patients who present sensory pathways which are at least partially preserved. Conversely, there are massive deafferentation pain syndromes (e.g., brachial plexus avulsion or amputation) in which the peripheral sensory pathways are severely or totally injured, precluding the use of intra-operative SEP. Objective. The authors present a simple technique for functional localization and intra-operative mapping of motor cortex by the implementation of transdural electrical stimulation of cerebral cortex for target refining of motor cortex during cortical electrode implantation procedures. ⋯ The proposed technique was useful for target refining in implantation of epidural electrode for motor cortex stimulation. Further studies are required to investigate if target refining by intra-operative mapping will significantly improve the results in the treatment of refractory pain.
