- Abstract:
- The study was designed to demonstrate the blood supply to the cervical cord through radicular branches and was carried out in 23 human cadavers into which preparations were injected by the intra-articular route. One corrosion cast of the head and neck showed extravertebral anastomotic pathways. After removal of the vertebral bodies and discs from C1 to D3, the anterior spinal artery and radicular branches were identified and dissected back to their origins from the vertebral, deep or ascending cervical arteries. Twelve preparations had only one or two radicular branches reaching the cervical spinal cord. If there is traumatic compression of an ascending branch a high risk of ischaemic damage to cranial areas of the spinal cord arises. The blood supply to the cervical enlargement of the spinal cord was provided by branches of the deep cervical artery in eight preparations, but only in one by branches of the vertebral artery. We therefore plead for decompression of the anterior spinal artery and the spinal cord and for sufficient arterial blood pressure, and give our reason for these demands.
