what are the criteria for thrombolysis treatment
thrombolysis treatment: Fluid passed through a catheter under a CT to unblock the clot.
cant be on anti-coagulants
INR greater than 1.7
has to be within 4 hours
2% chance of mortality
carotid endarterectomy
removing the clott under surgery from the artery.
carotid stenting
fine wire mesh passed into the artery under CT imaging
thromectomy
must get to the RVI within 6-8 hours.
catheter passed into artery and clot pulled out
common medications
anti-platelets anti-coagulants hypertensive medications cholestrol lowering anti-depressants
Treatments for stroke
carotid endaryerectomy thromectomy carotid stenting thrombolysis Rehabillitation
