Thrombolysis for Stroke

Because the brain relies on only two sets of major arteries for its blood supply, it is very important that these arteries are healthy. Then one of these blood vessels or its branches are suddenly blocked the brain tissue in that area stops functioning. If this block can be removed within the first 6 hours then, most of this tissue can be salvaged and the patient may have full recovery.
It is not only important to remove this block but it is also mandate lead to ascertain the cause of this block. Sometimes narrowing in the blood vessel that leads to the brain [stenosis] can be the underlying reason for this block. Since stenotic segments are prone to generate blood clots which can then flow into the cerebral circulation leading to stroke.
Today thanks to interventional radiology techniques a small catheter can be navigated right into the block and special proximal injected to dissolve and salvage the dying brain tissue. Further, the narrowing in the blood vessels can also be treated by angioplasty and stenting.
