G95.11

Clinical Causes: Arterial thrombosis within the spinal cord's blood vessels Embolic events, where blood clots or other particles block spinal arteries Anoxia or oxygen deprivation to the spinal cord tissues Atherosclerosis leading to narrowing of spinal arteries Vascular malformations or abnormalities disrupting blood flow Trauma or injury causing vascular damage Inflammatory or infectious processes affecting blood vessels

Key Symptoms: Sudden onset of weakness or paralysis in limbs or trunk Loss of sensation or numbness below the level of the infarction Severe back pain that may radiate or localize near the affected area Loss of bladder or bowel control Muscle spasms or stiffness Dizziness or lightheadedness in some cases Reduced or absent reflexes depending on the level and severity

Diagnosis Path: Diagnosis of acute spinal cord infarction involves a combination of clinical evaluation and diagnostic imaging. Initial assessments include neurological examinations to determine the level and extent of deficits. Imaging studies such as MRI are critical for visualizing spinal cord damage, showing areas of infarction, swelling, or bleeding. Additional tests may include vascular imaging techniques like angiography to identify blockages or abnormalities and blood tests to evaluate clotting factors or underlying risk factors. Differential diagnosis considers other causes of spinal cord symptoms, such as infections, tumors, or traumatic injuries.

Treatment Protocols: Management of spinal cord infarction aims to restore blood flow, prevent further damage, and support recovery. Immediate treatment may include medications to dissolve clots or anticoagulants to prevent new clot formation. Supportive care involves pain management, physical therapy, and rehabilitation to maximize functional recovery. In some cases, surgical intervention might be considered to remove clots or repair damaged vessels. Long-term management includes controlling risk factors like hypertension, cholesterol levels, and lifestyle modifications to prevent recurrence. Because of the severity and potential for permanent deficits, prompt medical attention is essential.
