ABSTRACT

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 São 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 braquiocefálico y de la arteria carótida común predisponen a complicaciones que pueden ser fatales durante una traqueotomía y/o cirugías. Con el objetivo de ampliar el conocimiento anatómico de estos vasos del cuello y de sus variaciones, decidimos diseccionar 110 cadáveres, formalizados, adultos, de ambos los sexos, provenientes del Laboratorio de Anatomía Descriptiva y Topográfica de la Universidad Federal de São Paulo-Escuela Paulista de Medicina ¡ UNIFESP-EPM. En 109 (99,1%) de los cadáveres no encontramos variaciones En un caso (0,9%) observamos variación en el trayecto del tronco braquiocefálico y de la arteria carótida común derecha.
