spinal cord infarction
Introduction
Introduction to spinal cord infarction Spinal cord infarction is a vascular lesion with further ischemia, necrosis and dysfunction on the basis of secondary ischemic spinal cord disease. Spinal blood vessels themselves such as atherosclerosis, arteriovenous, thrombosis, embolism; blood vessel pressure caused by lesions such as disc herniation, narrowing of spinal canal, intraspinal tumor, adhesive dura mater, arachnoiditis, etc. can cause Spinal cord ischemia or infarction. In the early stage of the lesion, spinal cord congestion and edema, softening lesion formation, and atrophy can be formed in the late stage. The principle of treatment of spinal cord infarction is the same as cerebral infarction. The comprehensive treatment is mainly used to improve the blood supply of ischemic foci by improving blood circulation drugs, to eliminate spinal cord edema and other neuroprotective treatment with dehydrating agent, and to supplement acupuncture and rehabilitation training. Pay attention to care and avoid complications such as hemorrhoids and urinary tract infections. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: paraplegia, acne, urinary tract infection
Cause
Cause of spinal cord infarction
Spinal cord thrombosis (caused by vascular stenosis, hypovolemia or hypercoagulable state) or embolism (cardiac or angiogenic) causes spinal cord infarction.
Prevention
Spinal cord infarction prevention
There are no particularly effective preventive measures, and early detection and early treatment are the key to the prevention and treatment of this disease. The principle of treatment of spinal cord infarction is the same as cerebral infarction. The comprehensive treatment is mainly used to improve the blood supply of ischemic lesions by improving blood circulation drugs, to eliminate spinal cord edema with dehydrating agents and other neuroprotective treatments, and to supplement acupuncture and rehabilitation training. Pay attention to care and avoid complications such as hemorrhoids and urinary tract infections.
Complication
Spinal infarction complications Complications, acne acne infection
The spinal cord is small in size and compact in structure. Once a lesion occurs, obvious symptoms will appear. The upper cervical lesion sometimes affects breathing and is life-threatening. And the disease is easy to cause paraplegia, hemorrhoids and urinary tract infections.
Symptom
Symptoms of spinal cord infarction Common symptoms Spinal cord disease Muscle atrophy Muscle tension Reduced Horsetail injury Deep sensory disturbance Sensory ataxia
Spinal cord symptoms often peak in a few minutes or hours. The anterior spinal artery syndrome occurs due to occlusion of the blood supply artery. It is more common in the middle thoracic or lower thoracic segment. The first symptom is often the corresponding part of the sudden lesion level. Root pain or diffuse pain, delayed sputum in a short period of time, converted to spastic paralysis after spinal shock period, conduction beam type separation sensory disturbance, painful sense of temperature loss and deep sensory retention (post-suspension is not affected), urine The obstacles are obvious, the posterior spinal artery syndrome, the posterior spinal artery is rarely occluded, even if it occurs, the symptoms of the collateral circulation are lighter and recover faster, showing acute root pain, deep sensory loss and sensory below the lesion level. Ataxia, pain temperature and muscle preservation, sphincter function is often unaffected, central artery syndrome, lower motor neuron sputum, muscle tone reduction, muscle atrophy, multiple sensory disturbances and pyramidal tract damage.
Examine
Spinal cord infarction
1. CT and MRI can clearly observe the internal structural changes of the spinal cord and the compression of the spinal cord by other tissues.
2. MRI diagnosis of spinal cord hemorrhage is sensitive and accurate. Observing the lesion is more sensitive.
3. Suspected of vascular damage and failure to find problems using conventional methods. Feasible spinal angiography.
Diagnosis
Diagnosis and diagnosis of spinal cord infarction
diagnosis
A diagnosis is made based on the patient's clinical symptoms and MRI examination.
Differential diagnosis
Need to be well identified with the following diseases:
(1) acute myelitis;
(2) Multiple sclerosis of the spinal cord;
(3) Green-Barre syndrome;
(4) Spinal cord compression, spinal cord tumor or spinal cord hemorrhage.
