What you talkin' about Willis
Disease
Stroke
Next Week's Lecture!
Venous Hemodynamics (Yay!)
100
This terminal branch of the internal carotid artery is NOT a part of the circle of Willis
What is the middle cerebral artery
100
The most common arterial pathology
What is Atherosclerosis
100
A neurological deficit lasting less than 24 hours
What is a Transient Ischemic Attack
100
High resistant flow in the distal ICA indicates this
What is distal disease (likely carotid siphon)
100
The relationship between venous flow and venous volume
What is indirect (inversely related)
200
These vessels serve as a communication between anterior and posterior circulation
What is the posterior communicating arteries
200
This pathology is described as a "Berry" and affects intracranial cerebral vessels
What is Saccular aneurysm
200
The inability to speak due to loss of understanding of language
What is Aphasia
200
An X-ray of arteries
What is an Arteriogram
200
A patient's measured blood pressure at the ankle when standing is 195mmHg, what is the true circulatory pressure
What is 95mmHg
300
What % of the population does not have an intact Circle of Willis
What is 80%
300
A distinguishing ultrasound feature of this pathology is the "neck", showing communication with the artery
What is a pseudoaneurysm
300
A stroke that is caused by a decrease in blood flow to the brain by arterial narrowing or blockage
What is Ischemic Stroke
300
The surgical removal of extracranial plaque and thrombus is associated with neointimal hyperplasia
What is an Endarterectomy
300
A ratio of change in the fluid volume to a change in pressure is known as
What is Compliance
400
This vessel allows blood flow to pass from right to left in the Circle of Willis
What is the Anterior Communicating Artery
400
Smoking, High Blood Pressure, and High Cholesterol can be classified as
What are controllable risk factors (for arterial disease)
400
Most common cause of ischemic strokes
What is Blot clot or Embolism
400
Bilateral dampened Common Carotid artery velocities are associated with this
What is low cardiac output
400
Approximately 40-60% of venous volume is ejected with contraction of this
What is the CALF (Venous Heart)
500
These vessels are capable of forming a collateral and are known as Periorbital Circulation
What is the Supraorbial artery and the superficial temporal artery
500
A difference of 20mmHg or more between brachial blood pressures indicates this pathology
Subclavian stenosis (Subclavian Steal)
500
The most common cause of Hemorrhagic strokes
What is Hypertension
500
This ECA waveform characteristic corresponds to the transient aortic pressure increase upon closure of the aortic valve
What is the dicrotic notch
500
The soleal sinus, common iliac veins, and IVC are all veins that have this in common
What is they do not contain valves
