Anatomia microcirúrgica da artéria coróidea anterior

Microsurgical anatomy of the anterior choroidal artery

Resumos

São apresentadas as características anatômicas da artéria coróidea anterior (AChA), encontradas nas dissecações de 100 hemisférios cerebrais de cadáveres humanos, realizadas sob microscópio cirúrgico. Foi encontrada uma AChA por hemisfério cerebral, 98% originando-se da artéria carótida interna (ACI) 2,4mm distai à origem da artéria comunicante posterior (ACoP) e 4,7mm proximal à bifurcação da ACI. Em 29% dos hemisférios havia ramos perfurantes emergindo da porção comunicante da ACI. A média do calibre da AChA foi 0,9mm na sua porção cisternal e 0,7mm na porção plexal. Os ramos mais freqüentes da porção cisterna da AChA foram para o trato óptico, pedúnculo cerebral, uncus e corpo geniculado lateral. Foram observadas anastomoses de ramos da AChA com ramos da artéria cerebral posterior, ACoP, artéria cerebral média e ACI. Os resultados são comparados àqueles da literatura.


Microdissection of 100 hemispheres from human cadavers were performed in order to study the anatomic characteristics of the anterior cheroidal artery (AChA). One AChA per hemisphere was found. In 98% of hemispheres the AChA arose from the internal carotid artery (ACI) 2.4mm distal to the origin of the posterior communicating artery (ACoP) and 4.7mm proximal to the carotid bifurcation. One or more perforating branches arose from communicating segment of ACI in 29% of hemispheres. The average calibre of the cisternal portion was 0.9mm and the plexal portion 0.7mm. The most frequent branches of the cisternal portion pass to the optic tract, cerebral peduncle, uncus and lateral geniculate body. Anastomosis were found between branches of the AChA and posterior cerebral artery, ACoP, middle cerebral artery and ACI. The results are discussed.

SUMMARY

Microdissection of 100 hemispheres from human cadavers were performed in order to study the anatomic characteristics of the anterior cheroidal artery (AChA). One AChA per hemisphere was found. In 98% of hemispheres the AChA arose from the internal carotid artery (ACI) 2.4mm distal to the origin of the posterior communicating artery (ACoP) and 4.7mm proximal to the carotid bifurcation. One or more perforating branches arose from communicating segment of ACI in 29% of hemispheres. The average calibre of the cisternal portion was 0.9mm and the plexal portion 0.7mm. The most frequent branches of the cisternal portion pass to the optic tract, cerebral peduncle, uncus and lateral geniculate body. Anastomosis were found between branches of the AChA and posterior cerebral artery, ACoP, middle cerebral artery and ACI. The results are discussed.
