Abstract

The anterior choroidal artery, although small, is an important cerebral vessel because of its strategiclocation and extensive area of supply. This paper summarizeds our study of arteriographic appearance of anteriorchoroidal artery in regard to plexal point, uncal point, cisternal segment, choroidal line and their relationship sin 50 consecutive normal Korean carotid angiograms. Results are as following. 1. Anterior choroidal artery arisesfrom carotid syphon of internal carotid artery in all cases. 2. Distance between plexal point and midline is 28.25-2.80mm, and varied from 23mm to 32mm. Distance between plexal point and superior border of orbit or petrousridge is 26.66±3.74mm, and varied from 20mm to 30mm. 3. The length of cisternal setgment in lateral projection is22.16±2.42mm, and varied from 17mm, to 29mm. 4. The distance between plexal point and choroidal line is 2.33±2.65mm, and varied from 3mm to 9mm. 5. Distance between uncal point and choroidal line is 4.16±2.22mm, andvaried from 0mm to 8mm.
