Resumen

Se estudian las arterias coroideas posteriores (ACP) en 26 cerebros humanos, utilizando como medio de contraste arterial silicona «rubber» o acrílica. Se identifican 51 ACP mediales, 26 (51%) en los hemisferios derechos y 25 (49%) en los izquierdos. Su origen fue el tronco de la arteria cerebral posterior en un 86,2% de casos, la calcarina y la parieto-occipital en un 5,9%, y la temporal en un 1,9%. Se localizan 78 ACP laterales, 40 (51,3%) sobre los hemisferios derechos y 38 (48,7%) en los izquierdos. Su origen tenía lugar en un 61,5% de casos en la arteria cerebral posterior, en un 10,2% en la temporal, en un 11,5% en la calcarina y en un 16,6% en la parieto-occipital.

Summary

The posterior choroidal arteries (ACP) were examined in 26 forebrain hemispheres injected with rubber silicone or acrylic silicone. A total of 51 medial ACP were found, 26 (51%) in the right hemispheres and 25 (49%) in the left hemispheres. These vessels originated from the trunk of the posterior cerebral artery in 86.2% of the cases, either the calcarine and parieto-occipital arteries in 5.9%, and the temporal artery in 1.9%. A total of 78 lateral ACP were described, 40 (51.3%) in the right hemispheres and 38 (48.7%) in the left hemispheres. These vessels originated from the posterior cerebral artery in 61.5% of cases, the temporal artery in 10.2%, the calcarine artery in 11.5% and the parieto-occipitalartery in 16.6%.
