Dear Mr Raghavendra
Ischemia of spinal cord: It means that less blood being supplied to the spinal cord.
Infarction or death of tissue is a result if ischemia is severe. In true sense cerebrovascular accident means effect on the brain. Spinal cord infarction is a separate entity and comes under category of Occlusive vascular lesions and spinal cord infarction is also known as
spinal stroke. However, mechanism both at brain and spinal cord are same i.e. less blood supply
