MANDIOLA, Eduardo et al. Biometrical Analysis of the Anterior Communicating Artery and the Anterior Cerebral Artery in the Precommunicating Segment of the Cerebral Arterial Circle. Int. J. Morphol. [online]. 2005, vol.23, n.2, pp.171-176. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022005000200012.

The conformation of the cerebral arterial circle has relevance in the clinical neurosurgery for the complex relate that present the arteries that originate it and its great variability. Due to the high frequency with that aneurysms are observed in the anterior communicant artery and the anterior cerebral artery in the precommunicating segment (A1), we have decided to make an analysis biometrical in them. The work had done in 36 available fresh brains in the laboratories and they come from specimens whose data bioanthropological were registered. The caliber of the anterior communicating artery corresponds to 1.68 mm and the longitude to 2.50 mm. The segment A1 of the anterior cerebral artery it corresponds to a longitude of 12.91mm and it presents a caliber of 2.39 mm in the right side. In the left side the longitude of this segment is of 12.77 mm and it presents a caliber of 2.46. In 29% of the analyzed samples, they register double communicating arteries, with a longitude of 2.92 mm and a caliber of 0.95 mm. Variability of the components is observed that they constitute the cerebral arterial circle when is considered: side, sex and cephalic index

Palabras clave : Anterior communicating artery; Anterior cerebral artery; Cerebral arterial circle; Cephalix index.
