| Sumario: | Abstract:
The vertebral artery has varieties in its origin, number and trajectory that oscillates between 3% and 7% according to the literature. There are not published national papers on serial dissections investigating vertebral artery varieties in fetuses. That is why from the Area of Microanatomy of the Chair of Normal Anatomy, of the Faculty of Medical Sciences (UNC) the study of the vertebral artery and its anatomical varieties was proposed from a sample from the city of Córdoba. The objective of the present study was to determine the incidence of anatomical varieties of the vertebral artery and to describe their morphology.
Studies were conducted on fetal cadaveric material provided by misericordia hospital, Córdoba. 97 fetuses of 15 to 22 weeks of both sexes, were dissected. Microdissection instruments, binocular magnifying glasses, Nikon 3300 machine with Nikon 105 mm lens were used. Details of normal anatomy and identification of vertebral artery varieties were recorded.
The following varieties were found: aberrant left vertebral artery in 3 cases, (3,09%), incidence within the ranges of the bibliography; double right vertebral artery in 1 case, (1,03%), from a common trunk are born 2 vertebral arteries that pass through the transverse foramens of the fifth and sixth cervical vertebra, variety not registered in the international literature.
This study contributes to the formation of a database indigenous to Córdoba, Argentina, of the incidence, morphological characteristics, and photographic documentation of the vertebral arteries. Knowledge of anatomical varieties serves health professionals who diagnose and/or perform interventions in this area to improve diagnoses and avoid therapeutic accidents.
