This study of the arterial blood of the spinal cord indicates that, of the 62 radicular branches (rami radiculares), at the most seven or eight truly participate in the vascularization of the spinal cord. The authors have observed that the situation and distribution of these branches enable the distinction of three large arterial areas: cervicothoracic,(More)
Mandibular reconstruction can be realized through use of an osteo-muscular flap of the temporal bone by a sagittal rotation around it's principal vessels. Experiments and anatomy study have desined the details of the technique which has been demonstrated in one clinical case. In spite of the necessity of neurosurgical collaboration the technique is easy and(More)
Few studies have been done about the venous vascularization of the spine since neuroradiologic studies in the 1960s and 70s. The aim of this study was to clarify the topography of the internal vertebral venous plexuses in relation to the posterior longitudinal ligament and the dura. The relationships of the vv. were studied at different levels of the spine.(More)
The authors described a method of vascular injection with a coloured silicon rubber. The injected material was a biocomponent silicon elastomer, with ambiant temperature room vulcanizing. It was supple, easily dissequable and diffuse well into all small caliber vessels. The soft pressure injection did not cause neither material collection by vessels rupture(More)
Typical e-mail travels through many computers. Every one who uses computers can read, copy, and store this e-mail. Many of the competitors in the businesses are highly motivated to intercept e-mail. Sending information about one’s business, legal, and personal mail through computers is even less confidential than sending the same material on a postcard.(More)
At the cervical level, in the foramen, the rachidian nerve is surrounded by two mantles: a dural one and a fibrous one continuing the epidural periosteal sheet of which it is a thickening. We can wonder whether this fibrous sheath is at the origin of some cervical radiculalgias in which one cannot detect any radiological lesion of the skeleton or disk.
