Variations in the trajectory of the brachiocephalic trunk and the common carotid artery predispose to disorders which might be critical in a tracheotomy and/or surgeries. Dissection of 110 formol fixed adult cadavers, both sexes, were performed to increase the anatomic knowledge of the neck vessels and its variations. Cadavers were from the Laboratory of Descriptive and Topographic Anatomy of the Federal University of S o Paulo- Paulista Medical School- UNIFESP-EPM. In 109 of these cadavers no variations were found while in one (0.9 %) it was possible to observe a variation in the trajectory of the brachiocephalic trunk and in the right common carotid artery. Las variaciones en el trayecto del tronco braquiocef芍lico y de la arteria car車tida com迆n predisponen a complicaciones que pueden ser fatales durante una traqueotom赤a y/o cirug赤as. Con el objetivo de ampliar el conocimiento anat車mico de estos vasos del cuello y de sus variaciones, decidimos diseccionar 110 cad芍veres, formalizados, adultos, de ambos los sexos, provenientes del Laboratorio de Anatom赤a Descriptiva y Topogr芍fica de la Universidad Federal de S o Paulo-Escuela Paulista de Medicina - UNIFESP-EPM. En 109 (99,1%) de los cad芍veres no encontramos variacionesEn un caso (0,9 %) observamos variaci車n en el trayecto del tronco braquiocef芍lico y de la arteria car車tida com迆n derecha.
