M47.012
Anterior spinal artery compression syndromes, cervical region
Clinical Classification Guidelines
Medical Intelligence & Overview
Anterior spinal artery compression syndromes in the cervical region refer to a group of neurological conditions caused by the compression or narrowing of the anterior spinal artery in the cervical spine. This artery supplies blood to a significant portion of the spinal cord, especially the anterior two-thirds. Compression can lead to ischemia (lack of blood flow), resulting in neurological deficits affecting motor and sensory functions. These syndromes are often associated with injuries, tumors, or other pathologies compressing the artery in the cervical area, leading to various degrees of neurological impairment depending on the severity and duration of blood flow interruption.
Causes & Symptoms
Clinical Causes: Spinal tumors or neoplasms that exert pressure on the anterior spinal artery Traumatic injuries causing fractures or dislocations impinging on the artery Degenerative disc disease leading to osteophyte formation that compresses the artery Vascular malformations or aneurysms in the cervical region Infections or inflammatory conditions causing swelling and compression Post-surgical complications involving the cervical spine
Key Symptoms: Sudden loss or weakness of muscle strength (paralysis) below the level of the lesion Loss of pain and temperature sensation on the anterior (front) part of the body Preservation of vibration sense and proprioception (position sense) since these are supplied by the posterior spinal artery Difficulty in controlling bladder and bowel functions Localized neck pain or stiffness at the level of injury In severe cases, respiratory difficulties due to involvement of cervical spinal cord segments controlling breathing
Diagnostic & Treatment
Diagnosis Path: To diagnose anterior spinal artery compression syndromes, healthcare providers may use several approaches:
Treatment Protocols: Managing anterior spinal artery compression syndromes involves addressing the underlying cause and supporting neurological function:
