What exactly is a stroke?

Rapidly developing loss of brain function due to a disturbance in the blood supply to the brain.

Two types of strokeIschemic – lack of blood flow – usually from a clotHemorrhagic – ruptured blood vessel

Ischemic (Blood Clot) StrokeNeurology ConsultEstablish onset of symptoms – 3 hour windowConsider “Clot Busting” medicine (TPA)

NINDS Study624 ischemic stroke patients enrolledCompared TPA to PlaceboTreatment within 3 hours of symptom onsetResults:

At 3 months, TPA treated patients 30% more likely to have minimal or no neurologic deficits11‐13% overall increased favorable outcome

*TPA group did have increased rate of bleeding in the  brain (6.4% vs. 0.6%)

Criteria for TPAAge > 18Time of onset < 3 hoursNo improving symptomsNo surgery within preceeding 14 daysBlood pressure controlled ( < 185 / 110)No Previous stroke (within 90 days)No GI/GU bleeding (within 21 days)No seizure

SNHMC Telestroke Program

Partnership with Massachusetts General Hospital

Telemedicine has become an accepted standard of care

Allows for bedside consultation with an MGH neurologist and neuroradiologist
