Visual outcome after fronto-temporo-orbito-zygomatic approach combined with early extradural and intradural optic nerve decompression in tuberculum and diaphragma sellae meningiomas.
The surgical challenge of the treatment of tuberculum (TSMs) and diaphragma sellae meningiomas (DSMs) is to preserve or improve the visual function. Extradural and intradural optic nerve decompression should reduce surgical trauma of the nerve achieving a good visual result. ⋯ Using this surgical technique we achieved a high improvement rate of visual defects and a low frequency of worsening.

Distribution of delayed ischemic neurological deficits after aneurysmal subarachnoid hemorrhage and implications for regional neuromonitoring.
Many neuromonitoring devices provide data applicable to a limited region of the brain. Risk of DIND is common after aSAH and may occur near or remote from the ruptured aneurysm. The aim of this study is to determine the distribution of DIND after aneurysms rupture as it relates to the potential value of regional monitoring in detection of vasospasm. ⋯ Vasospasm related infarction occurs most commonly ipsilateral to or in the same distribution of the ruptured aneurysm. Less anatomical correlation is seen with midline aneurysms. Rupture of posterior circulation aneurysms infrequently results in supratentorial infarction. Decisions regarding placement of regional monitors for the purpose of vasospasm detection should consider this distribution of ischemic risk.
