The research field in fetal anatomy has been overlooked during the last decades in Argentina. From the Microanatomy Area, Chair of Normal Anatomy, School of Medicine, National University of Cordoba we are recently addressing this gap in the morphological research field. The bovine trunk is an anatomical variation in the origin of the supra aortic vessels, which consists in the brachiocephalic trunk or innominate artery and left common carotid artery sharing a common origin at the aortic arch. The focus of this research paper is set on anatomical variations for which scarce descriptive morphological literature exist. This comprises the anatomical variation previously described, as well as those of the bicuspid aortic valve, aberrant left vertebral artery and the arterial duct. The objective of this study was to describe the normal foetal morphology and the anatomical variations of the following vessels: aortic arch y bovine trunk, left vertebral artery y aberrant, aortic valve y bicuspid variation; abdominal aorta artery y its branches; situs inversus totalis, in order to analyse the frequency of these anatomical variations in a sample from Córdoba City.
The study was performed on cadaveric samples of human foetuses donated by a public hospital (Misericordia Hospital) located in Cordoba City. A series of 85 foetuses of 12 to 15 weeks, male and female, were dissected. For this purpose, microdissection instruments, binocular magnifying lenses and camera Nikon 3300, lens Nikon 105 mm were used. Detailed record and description of the normal anatomy was carried out, as well as the identification of its variations concerning supra-aortic vessels, vertebral arteries, aortic valve and abdominal aortic branches.
We found anatomical variations in the cardiovascular system and in the anatomical disposition of the thoracoabdominal organs. The incidence of these findings was as follows: situs inversus totalis 1.18%, supra aortic bovine trunk 7.06%; aberrant left vertebral artery 4.71%; bicuspid valve 1.18% y double right renal artery 1.18%; the other abdominal aortic branches presented normal anatomy in all cases.
This study gave place to an original data base and photographic record of the fetal morphology, which previously was underdeveloped or completely missing. Knowledge of anatomical varieties improves diagnosis and treatment because it avoids medical mistakes and complications. |

Es por ello que desde el Área de Microanatomía de la Cátedra de Anatomía Normal, FCM-UNC, nos propusimos desarrollar esta temática. El tronco bovino es una variedad en el origen de los vasos supra-aórticos que consiste en compartir el mismo origen en el arco aórtico del tronco braquicefálico y la arteria carótida común izquierda; esta variedad junto a la válvula aórtica bicúspide, arteria vertebral aberrante izquierda y el ductus arterioso normal tienen escasos estudios morfológicos descriptivos, a partir de la disección anatómica, eje principal de esta investigación. El objetivo del presente trabajo fue describir la morfología normal fetal de las siguientes regiones y sus variedades anatómicas: disposición general, situs inversus totalis; cayado aórtico y el “tronco bovino” supra-aórtico, arteria vertebral normal y aberrantes, válvula aórtica y su variedad bicúspide; aorta abdominal y el nacimiento de sus respectivas ramas, para así obtener la frecuencia de las variedades anatómicas en una muestra de la ciudad de Córdoba. Se realizaron los estudios en material cadavérico fetal cedido por el Hospital Misericordia, Córdoba. Se disecaron 85 fetos de 12 a 15 semanas, de ambos sexos. Se utilizó instrumental de microdisección, gafas lupas binoculares, máquina Nikon 3300 con lente Nikon 105 mm. Se registraron los detalles de la anatomía normal e identificación de sus variedades: vasos supra-aórticos, arterias vertebrales, válvula aórtica; ramas de la aorta abdominal. Se hallaron variedades anatómicas en el sistema cardiovascular y en la disposición anatómica de los órganos toraco-abdominales; con la siguiente incidencia: situs inversus totalis 1,18%, “tronco bovino” supra-aórtico 7,06%; arteria vertebral izquierda aberrante 4,71%; válvula bicúspide 1,18% y arteria renal derecha doble 1,18%; las ramas de la aorta abdominal se encontraron con anatomía normal. Este estudio permite construir una base de datos y documentación fotográfica original de la morfología fetal que se halla poco desarrollada en este medio. El conocimiento de las variedades anatómicas en general y de las encontradas en este trabajo sirven a los profesionales de la salud que actúan en las citadas regiones para mejorar los diagnósticos y evitar accidentes intraoperatorios.
