Experimental Embolic Occlusion of a Single Leptomeningeal Artery

摘要: Despite many advances in the study of cerebral circulation man and other animals, little is known anatomy especially pathophysiology smaller leptomeningeal arteries their intraparenchymal terminations. Most previous studies have been performed on larger vessels representing highest "levels" vasculature. The concentration work carotids anterior, middle, posterior has resulted much information effects, or lack when these are occluded. Although lower levels observed through windows, relatively obtained deep distribution branches consequences occlusion.

His angioarchitectonic revealed that penetrating cortex sparse anastomoses, but capillaries communicated freely.
