pubmed:abstractText |
Most of the small (50--60 micrometers) vessels nourish exclusively the cerebral cortex, whereas larger caliber (80--150 micrometers) arteries penetrate the entirety of the cortical layer to enter the underlying white matter. A single layer of nonfenestrated endothelial cells, surrounded by a continuous layer of basement membrane (which in places splits to envelope a pericyte), and perivascular glial cells attached to the outer surface of this basement membrane, with no pericapillary space, represent the anatomical structure of the blood-brain barrier (BBB). Concentrated electrolyte solutions and increases in mean arterial pressure may reopen the BBB. Water-soluble contrast media used in cerebral angiography are hypertonic solutions of iodinated salts. In cerebritis, one observes a very typical angiographic picture: 'laminar' staining of the gyri. The intervening sulci appear as negative images. In brain abscess, one may note angiographic evidence of a space-occupying lesion, a capsular stain in the granulation tissue surrounding the abscess, 'halo' formation and 'pooling' of contrast media in the sulci, and 'laminar' staining of the gyri.
