Effects of superficial temporal artery-middle cerebral artery bypass on hemodynamics and clinical outcomes in the patients with atherosclerotic stenosis in the intracranial segment of internal carotid artery and middle cerebral artery.
To observe the effects of superficial temporal artery-middle cerebral artery bypass (STA-MCA bypass) on hemodynamics and clinical outcomes in the patients with atherosclerotic stenosis in the intracranial segment of internal carotid artery and (or) middle cerebral artery. ⋯ STA-MCA bypass can improve cerebral blood perfusion and reduce the incidence of stroke in the patients who have ISICA and (or) MCA-related symptoms, 70%-100% of stenosis, and above stage-ⅠCTP. However, this conclusion remains to be further confirmed.

Intraoperative neuromonitoring during microsurgical clipping for unruptured anterior choroidal artery aneurysm.
To investigate the safety and unexpected finding of the intraoperative neuromonitoring (IONM) including somatosensory evoked potentials (SSEPs) and motor evoked potentials (MEPs) during microsurgical clipping of an unruptured anterior choroidal artery (AChA) aneurysm. ⋯ IONM including transcranial MEP during microsurgical clipping of unruptured AChA aneurysm might have limited usefulness. Therefore, other MEP monitoring using direct cortical stimulation or modified transcranial methodology should be considered to compensate for it.

Embolization of the Middle meningeal artery in chronic subdural hematoma - A systematic review.
Chronic subdural hematomas (cSDH) are one of the most frequent reasons for consultation in neurosurgery. Multiple authors have proposed middle meningeal artery embolization (MMAE) as an option in cSDH patients to manage recurrence or avoid surgery altogether. Although many articles have been published on the matter, the current body of evidence still has to be evaluated before MMAE is integrated into clinical practice. ⋯ Although the definition of resolution varied among authors, cSDH resolution was reported in 96.8% of cases. MMAE is a feasible technique for cSDH, but the current body of evidence does not yet support its use as a standard treatment. Further studies with a higher level of evidence are necessary before MMAE can be formally recommended.

Comparative StudyConservative versus operative treatment in supratentorial intracerebral hemorrhage - A survey among neurosurgeons and neurologists in Germany.
Decision making for surgical therapy in patients with intracerebral hemorrhage is still controversial among neurologists and neurosurgeons. Whereas neurologists may favor conservative treatments, surgeons may opt for operations. This might lead to different therapy decisions. ⋯ Against common prejudices, the process of decision making for or against surgery in patients with spontaneous intracerebral hemorrhage is comparable among conservative physicians (neurologists) and neurosurgeons in Germany. This might be the result of joint efforts in spontaneous intracerebral hemorrhage (ICH) therapy, such as joint guidelines or a society of neurointensive care medicine.

Predictors and clinical features of transient neurological events after combined bypass revascularization for moyamoya disease.
Transient neurological events (TNEs) are frequently observed after revascularization surgery for moyamoya disease (MMD). However, clinical features and pathophysiology of TNEs in MMD are still unclear. This study was aimed to clarify the incidence and time course of TNEs and to determine the independent predictors of TNEs in MMD. ⋯ Female, left-sided surgery and edematous lesion were independent risk factors for postoperative TNEs; the left-sided surgery and edematous lesion were also independently associated with the severity of TNE. Although patients with postoperative TNEs had worse neurological status during the perioperative period, postoperative TNEs had no associations with worse mRS score at the time of discharge.
