Encephaloduroarteriosynangiosis (EDAS) is a promising treatment for cerebral arterial steno-occlusive disorders, with proven efficacy in moyamoya disease and a growing interest in potential application for patients with symptomatic intracranial atherosclerotic disease, given the early results of intermediate development trials showing reduced rates of recurrence stroke and improved clinical outcomes compared with those patients treated with intense medical management (IMM) alone. Although clinical outcomes are the fundamental goal when considering patient care paradigms, a cost-effective analysis is key to obtaining a comprehensive understanding of the impact EDAS may provide to patients with atherosclerotic disease on a larger scale. Here, we evaluate the EDAS + IMM cost-effectiveness over time in the treatment of intracranial atherosclerotic disease compared with IMM alone.

It remains unknown if the progressive loss of axonal conduction along sensorimotor tracts can be recovered after surgery in patients with degenerative cervical myelopathy (DCM) and if subsequent adaptive microstructural changes are associated with the neurological improvement. ⋯ Recovery of microstructural integrity along the corticospinal tract and other sensorimotor pathways, together with supraspinal reorganization of microstructural connectivity within sensory and motor-related regions, was associated with neurological improvement after surgical decompression.

The Importance of the Temporary Clip Removal Phase on Exposure to Hypoxia: On-Line Measurement of Temporal Lobe Oxygen Levels During Surgery for Middle Cerebral Artery Aneurysms.
Most studies concerning intraoperative temporary arterial occlusion overlook the period between and after clip placement. ⋯ During the clip removal phase, the brain tissue is still exposed to oxygen levels that are significantly below the baseline, reverting through a singular, dynamic process. Therefore, it must be regarded by surgeons with the same degree of attention as its counterpart.
