A3_Acute Ischemic Stroke Flashcards
What are the diagnostic procedures to distinguish the root cause of Acute Ischemic Stroke?
MRI, Angiography, ECG/EKG
What is the main treatment of Ischemic Stroke which can break up blood clots?
tPA (Tissue Plasminogen Activator)
What is the most common presentation of acute ischemic stroke?
Speech disturbance and one sided weakness
What is the tissue that surrounds the ischemic area that received some perfusion?
PENUMBRA
A descriptive term for the sudden onset of acute neurologic deficit persisting for more than 24 hours and caused by the interruption of blood flow of the brain
STROKE
A complex series of cellular metabolic events that occur when there is a disruption in blood flow
ISCHEMIC CASCADE
The blood supply to the brain can be altered via 4 mechanisms. Identify what are these mechanisms
Embolism
Thrombosis
Hemorrhage
Compression or spasm of the vessels
The blood supply to the brain can be altered via 4 mechanisms. Identify what are these mechanisms
Embolism
Thrombosis
Hemorrhage
Compression or spasm of the vessels
It is a neurologic dysfunction typically lasting less than an hour with presenting signs of unilateral weakness of the face, arm and leg, unilateral altered sensation, dysphasia, monocular blindness and Hemianopia
Transient Ischemic Stroke
What is the goal of initial diagnosis during a stroke?
To differentiate if it is a hemorrhagic or a ischemic stroke
A condition wherein patients are considered non-comatose and has a full awareness of what’s happening. This is caused by a brain stem hemorrhage or infarct and also known as pseudocoma
Locked in syndrome
Acute Ischemic Stroke occurs when the blood flow to the main artery is blocked by ____
CLOT
Can Acute Ischemic Stroke be treated?
It can be treated by dissolving the blood clots or having it surgically removed
Results from an interruption of blood flow to the brain, and accounts for 80-85% of all strokes?
ISCHEMIC STROKE
What are the two types of ischemic stroke?
THROMBOTIC & EMBOLIC
