Thrombectomy for Ischemic Stroke & Endovascular treatment for stroke

Question 1

When is thrombectomy used?

Answer 1

In ischemic stroke only where large vessels are occluded.

Question 2

What vessel occlusions is thrombolysis used for?

Answer 2

Carotid
Middle cerebral
Basilar arteries
Some M2 branches

Question 3

How does collateral supply effect the progression of ischemic stroke?

Answer 3

If there are collateral arteries supplying the same area that the occluded artery does the rate at which the brain tissue will degrade at will decrease.

Question 4

How can BP effect the progress of ischemic stroke?

Answer 4

If there is a large artery occlusion the body will react by shunting up BP to compensate and therefore perfuse the brain more and decrease the rate at which brain tissue degrades.

Answer 5

85% ischemic

15% hemorrhagic

Stentriever

Question 8

Answer 8

Within 6 hours

Question 9

What level of the modified rankin scale must the patients brain function be to justify thrombectomy?

Answer 9

Below or equal to 3

Question 10

What level should core infarct volume be to justify thrombectomy?

Answer 10
