Peripheral Vascular Disease Flashcards
What two subcategories are there for PVD?
Acute arterial occlusion and atherosclerotic occlusive disease
What causes an acute arterial occlusion?
A thrombus or embolus which lead to ischemia and then infarction
What are the characteristics of atherosclerotic occlusive disease?
Atherosclerotic plaques develop slowly and and increased prevalence in elderly and people with diabetes
What is a manifestation of atherosclerotic occlusive disease in PVD?
Intermittent claudication which is ischemic pain
How does the body compensate for the atherosclerotic plaque in PVD
Vasodilation, collateralization, anaerobic metabolism
In PVD, why is vasodilation a minimally successful compensation done by the body?
Because of the “hardened” arteries
What is the ramification of anaerobic metabolism as a compensation in PVD
Anaerobic metabolism has a byproduct of lactic acid which creates metabolic acidosis and loss of fx
What occurs if there is no treatment for PVD?
Ulceration and gangrene occur then amputation is necessary
Where does atherosclerotic occlusive disease most commonly occur?
In the arteries in the legs
