ABSTRACT

The objective of the present study is to determine origin, entry level to the transverse foramen and diameter according to sex and side through 3D angiographic images of seventy-nine vertebral arteries obtained using DSA imaging method. During radiological evaluation, axial, coronal and sagittal images of the artery were used. Data of our study was uploaded to SPSS 14.0 program and significance test and Mann Whitney-U test of the difference between two means were used to evaluate the data. While 76 of the vertebral arteries (96.2%) were originating from the subclavian artery, 3 of them (3.8%) were directly originating from aortic arch. In 67 of 76 the vertebral arteries originating from the subclavian artery were entering through C6, 6 through C7, 2 through C5 and one through C4 transverse foramen. It was seen that one of 3 the vertebral artery originating from aortic arch was entering through C6, one through C7 and the other through C4 transverse foramen. While the mean diameter of the vertebral artery was 3.88±0.71 mm at the right side (3.99 mm in men, 3.66 mm in women), the mean diameter at the left side was 4.15±1.05 mm (4.23 mm in men, 4.06 mm in women).


El objetivo fue determinar el origen, nivel de entrada y diámetro del foramen transverso, en función del sexo y lado sobre 79 arterias vertebrales a través de imágenes angiográficas 3D utilizando el método de formación de imágenes DSA. Durante la evaluación radiológica, se utilizaron imágenes axiales, coronales y sagitales de la arteria. Los datos se procesaron en el programa SPSS 14.0 con las pruebas U de Mann Whitney y de significancia para evaluar la diferencia entre los datos. Mientras que 76 de las arterias vertebrales (96,2%) se originaron de la arteria subclavia, 3 de ellas (3,8%) lo hicieron directamente desde el arco aórtico. En 67 de 76 arterias vertebrales, se observó el origin en la arteria subclavia a través de C6; 6 a través de C7, 2 a través de C5 y una a través del foramen transverso en C4. El diámetro medio de la arteria vertebral fue 3,88±0,71 mm en el lado derecho (3,99 mm en hombres y 3,66 mm en mujeres) y en el lado izquierdo fue 4,15±1,05 mm (4,23 mm en hombres y 4,06 mm en hombres).
