Current Status of Endovascular Treatment for Vasospasm following Subarachnoid Hemorrhage: Analysis of JR-NET2.
Endovascular treatments are employed for cerebral vasospasm following subarachnoid hemorrhage, which is not responded to the medical treatments. However, the effect or complication of the treatments is not known well. Here, we analyzed the data of Japanese Registry of Neuroendovascular Therapy 2 (JR-NET2) and revealed current status of the endovascular treatment for the cerebral vasospasm. ⋯ Statistical analysis showed early treatment was related to the neurological improvement. Current status of endovascular treatment for cerebral vasospasm was revealed. Endovascular treatment was effective for vasospasm especially was performed early.

ReviewUpdate on intensive neuromonitoring for patients with traumatic brain injury: a review of the literature and the current situation.
Intracranial pressure (ICP) measurements are fundamental in the present protocols for intensive care of patients during the acute stage of severe traumatic brain injury. However, the latest report of a large scale randomized clinical trial indicated no association of ICP monitoring with any significant improvement in neurological outcome in severely head injured patients. Aggressive treatment of patients with therapeutic hypothermia during the acute stage of traumatic brain injury also failed to show any significant beneficial effects on clinical outcome. ⋯ However, combined application of different types of neuromonitoring, including ICP measurement, may have potential benefits for understanding the pathophysiology of damaged brains. The combination of monitoring techniques is expected to increase the precision of the data and aid in prevention of secondary brain damage, as well as assist in determining appropriate time periods for therapeutic interventions. In this study, we have characterized the techniques used to monitor patients during the acute severe traumatic brain injury stage, in order to establish the beneficial effects on outcome observed in clinical studies conducted in the past and to follow up any valuable clues that point to additional strategies for aggressive management of these patients.

Recent advances and future directions of hypothermia therapy for traumatic brain injury.
For severe traumatic brain injury (TBI) patients, no effective treatment method replacing hypothermia therapy has emerged, and hypothermia therapy still plays the major role. To increase its efficacy, first, early introduction is important. Since there are diverse pathologies of severe TBI, it is necessary to appropriately control the temperature in the hypothermia maintenance and rewarming phases by monitoring relative to the pathology. ⋯ Brain temperature management was performed mainly in young patients, and the outcome on discharge was favorable in patients who received brain temperature management. Particularly, patients who need craniotomy for removal of hematoma were a good indication of therapeutic hypothermia. Improvement of therapeutic outcomes with widespread temperature management in TBI patients is expected.

Comparative StudyHemorrhage rates associated with two methods of ventriculostomy: external ventricular drainage vs. ventriculoperitoneal shunt procedure.
Cerebrospinal fluid (CSF) diversion is an essential component of neurosurgical care, but the rates and significance of hemorrhage associated with external ventricular drainage (EVD) and ventriculoperitoneal (VP) shunt procedures have not been well quantified. In this retrospective study, the authors examined the frequencies of hemorrhagic complications associated with EVD and VP shunt procedures, and attempted to identify associated risk factors. The treatment records of 370 EVDs in 276 patients and 102 VP shunts in 96 patients performed between 2008 and 2010 were retrospectively reviewed. ⋯ Ventriculostomy-related hemorrhagic complications were more common than anticipated, especially for the VP shunt procedure. However, such hemorrhages are rarely large, rarely the cause of neurological deterioration, and rarely require surgical removal. Preoperative anti-platelet medication appears to affect EVD-related hemorrhage development.

A simple, 10-minute procedure for transforaminal injection under ultrasonic guidance to effect cervical selective nerve root block.
The aim is to provide a detailed procedure of a simple and 10-minute cervical nerve root block (CNRB) under ultrasonic guidance, and to report the clinical outcomes, disorders, and complications. Records of patients who had undergone CNRB, were reviewed under ultrasonic guidance at the hospital from 2010 through 2012. The procedure is described in detail. ⋯ At the final follow-up periods, 17.2 (10-24 months), the median VAS score of the patients, 23 (0 to 71 mm), was significantly improvement (P = 0.001) in comparison to before injection 88 (range; 56-100). No complications occurred. The cervical nerve root block under ultrasonic guidance simply, safely, and efficaciously decreased radicular pain for 17.2 months in 62% patients with intolerable radicular pain.
