‘ ‘ THE ACUTE CEREBROVASCULAR ACCIDENT ( CVA ) STROKE
The acute stroke usually occurs as two distinct possibilities :
1…..Intracerebral Hemorrhagic
2…..Acute Ischemic ( Thrombosis or embolus of cerebral artery )
The acute ischemic CVA occurs when the blood supply is disrupted to a given portion of the brain : e.g., if the left middle cerebral artery becomes thrombosed, much of the left hemisphere will infarct. The clinical presentation will be highly variable but will often include dysphasia and right hemiparesis—- plus others.
The treatment mode for the acute Ischemic CVA is highly variable including :
1…..Supportive only.
2…..Surgical intervention.
3…..Thrombolytic therapy.
4…..Anti-coagulants and anti-platelets.
. . RISK FACTORS FOR STROKE
· ..Advanced age
· ..Hypertension
· ..Previous stroke or TIA ( Transient Ischemic Attack )
· ..Diabetes Mellitus
· ..Atrial Fibrillation — at risk for thromboembolism ………………………………..from left atrial thrombus
· ..Cigarette smoking
· ..Elevated cholesterol
· ..Anticoagulant, antiplatelet medication

Immediately post ischemic stroke the CT scan may be essentially normal. After a few hours you will begin to see the evolutionary changes— The next image shows a CT 12 hours post thrombosis of the left middle cerebral artery .—–
