“…The radiculae produce a patern resambling a crescent moon [15] spreading diffusely and filling the posterior aspect of the lumbar subarachnoid space [16,17]. Three papers on MRI present excelent information on the anatomy of the thoracic vertebral canal [18][19][20].…”

“…Studying the cervical and thoracic column through MRI it is evident that the spinal cord is adhered posteriorly in the cevical region and anteiorly in the thoracic segment [20]. The lateral approach between C1 and C2 is point of choice for mielography.…”

“…The evaluation of the subarachnoid space with the patient in the supine position has shown that the distance between the dura-mater and the spinal cord in the thoracic segment is greater in the midthoracic point than cephalad or cauddad [20]. Neuraxial blocks are realized with the patient in the lateral position or seated.…”

“…On top of the thoracic curve the spinal cord is kep steady by the denticulate ligament, being that in this localization it stays anteriorly. With the knowledge of the anatomy of the thoracic column recently evaluated [20], it is expected that the patient in dorsal decubitus or in the sitting position the exagerated curvature of the column may displace the spinal cord more anteriorly, what would reduce the risk of damage of the neural tisssue by the needle of the anesthesist.…”

In 1909 Thomas Jonnesco published his interesting paper under the title General spinal anesthesia through an approach of the subarachnoid space at a thoracic level, providing condition for surgery on the skull, head, neck and thorax. Etherington-Wilson proposed explaining the various possibilities for the spinal anesthesia. Leonardo da Vinci was considered the discoverer of Human and animal Anatomy. Image techniques have opened a gret new field for the study of anatomy in the living man. The modern means of image, associated to computed means have facilitated the evaluation of the CSF volume, through antero-posterior and height measures of the subarachnoid space based on bi-dimentional studies of MRI. The studies of the thoracic column with MRI show that exist a space between the dura-mater and the spinal cord (medula). Thoracic ouncture performed with needles proved safe and without neurological injury. Thoracic spinal anesthesia is a viable procedure, with a low incidence of hypotension and did not present any neurologic problem.

“…The rootlets form a pattern similar to a crescent shape 12 spreading diffusely and occupying the posterior region of the lumbar space 13,14 . The MNR has provided detailed information on the anatomy of the thoracic vertebral canal [15][16][17] . Van Zundert 18,19 and Imbelloni 20 described the performance of the combined spinal-epidural block through thoracic puncture, without complications.…”
