1. Blood supply to the spinal cord

2. Spinal cord infarction
Infarct of the spinal cord – uncommon
The region fron T4 to T8 contains few anastomoses – the gratests ischemic risk, especially in patients with systemic hypotension
Causes: hypoxia, ischemia cardiogenic embolism, vasculitis, AS, hypercoaguloability

3. Spinal cord infarction clinical findings
Sudden onset of symptoms
Moderate to severe back pain followed within inutes by paraparesis or paraplegia
Loss of pain sensation below the level of infarction bilaterally
Loss of bladder control

4. Spinal cord infarction diagnostic studies and therapy
CSF - hyperproteinorhachia
MRI and CT – negative during 24 hours
MRI – few days later – focal cord swelling
Liečba – therapy of the cause, antiagregant therapy, prognosis is not very good

5. Spinal cord infarction - MRI
T2-weight picture

6. Hematomyelia Bleeding to the spinal cord Bleeding from AVM
Coagulopathy
Myelitis
Bleeding to spinal cord tumors
Traumatic bledding

7. Hematomyelia Sudden onset of symptoms
Moderate to severe back pain followed within inutes by paraparesis or paraplegia
Loss of pain sensation below the level of infarction bilaterally
Loss of bladder control
Therapy – conservative or surgery

8. Hematomyelia - MRI
