Flashcards in Peripheral Vascular Disease Deck (9):

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
