摘要:

&NA;This case required the clipping of a single branch of the middle cerebral artery for the treatment of a traumatic aneurysm. To ensure an adequate blood supply distal to the occlusion, we anastomosed the superficial temporal artery to that branch of the middle cerebral artery (MCA) distal to the aneurysm. Despite the low flow required to irrigate only one branch of the MCA, the anastomosis remained patent. This case demonstrates the feasibility of performing small vessel anastomoses in spite of low flow demand.

摘要:

&NA;Cerebral edema remains a major clinical problem despite intense investigation and multiple therapeutic interventions. In this review the author summarizes the major issues involved and the current experimental and clinical work being done in the areas of etiology, mechanisms, and treatment. Emphasis is placed on the importance of the blood‐brain barrier, astroglial compartmentalization of ions, energy considerations, the relationship of cerebral edema to increased intracranial pressure, and resolution of the process. Current treatment modalities and their efficacy are discussed in terms of our present knowledge of the issues involved.

摘要:

&NA;Present and potential applications of scanning electron microscopy (SEM) to the study of solid neoplasms, the lining of cysts, exfoliated cells, mineral deposits, and supporting tissues of the central nervous system (CNS) are discussed. Special features of the SEM image include a large field of view and depth of focus, high resolution, and a three‐dimensional impression of surface topography. These features have contributed a clearer understanding of similarities between colloid cyst and olfactory epithelium. They demonstrated differences between glial and nonglial fibrils of selected CNS neoplasms. These features may ultimately enhance detection, diagnosis, and study of neoplastic origins and spread within the CNS and cerebrospinal fluid. Special features of tissue examination by SEM include processing without the need of thin sections and elemental analysis by X‐ray spectroscopy. These features have been applied to studies of calcium and thorium associated with meningiomas and a schwannoma.
