Innovation in Stroke Treatment


[Dr. Dileep Yavagal, UHealth stroke neurologist]
In 2018, we had a major revolution, almost, in the treatment of stroke. Where we previously were able to treat acute
stroke paralysis only up to six hours and now we are able to do so
up to 24 hours in selective patients. This is really a big step forward
because it gives us four times the amount of time to identify, bring the patients to the right
stroke center, and open up the blocked artery in the brain in the patient who has a brain
that can be salvaged. What we found in the two studies that looked at extending this window was that almost 50 percent of patients did have some brain to save when they had severe stroke symptoms. So this is really a big deal because we couldn’t do much for stroke only just a decade ago. And, just in the last five years, we were
first able to do this up to six hours, and then this year,
we are able to now move it up to 24 hours. Once the patient is brought here,
we do this special CT scan (called CT Perfusion) and sometimes an MRI. And those patients that have brain—a significant amount of brain to save—are brought to the angiography suite, like this,
to get a procedure called thrombectomy. It’s also known as mechanical thrombectomy. Where from the groin through a small hole, we bring up a catheter using the advanced x-ray navigation into
the blocked artery in the brain. We use the arterial highway to come up to
the blocked artery in the brain, and then using a device, either suck the clot out
or engage the clot and bring it out with something called a stent retriever,
and bring the blood flow back into the brain. We want to make stroke like a bone fracture,
where we basically are able to repair the stroke completely in all patients.
