Anterior spinal artery

Organization and role

Radiculomedullary arteries reinforce the blood supply. Spinal circulation varies between individuals and is not simply one continuous vessel with uniform flow.

Clinical relevance and investigation

Vascular insufficiency may cause acute cord injury. Sudden weakness with sensory or sphincter changes requires hospital assessment rather than mechanical therapy.

Points to consider

Neural tissue depends on continuous blood supply. A vessel disorder can have consequences different from disc compression, even when symptoms overlap. Sudden weakness or new loss of function requires urgent assessment.

Role of TAGMED care

At TAGMED, assessment aims to understand symptoms, history and functional limitations. Manual care and osteopathy, motorized spinal decompression, laser and shockwave have different indications. The term described in this entry is not enough to select any of these modalities. Their relevance, limitations and possible contraindications should be discussed in relation to diagnosis and individual goals.

Related concepts and distinctions

• Artery of Adamkiewicz — Large anterior radiculomedullary artery reinforcing thoracolumbar spinal cord blood supply, with a variable origin and course.
• Vertebral artery — Artery usually arising from the subclavian artery, passing through cervical transverse foramina before contributing to posterior brain circulation.
