Flashcards in Peripheral Vascular Disease Deck (9):
1

What two subcategories are there for PVD?

Acute arterial occlusion and atherosclerotic occlusive disease

2

What causes an acute arterial occlusion?

A thrombus or embolus which lead to ischemia and then infarction

3

What are the characteristics of atherosclerotic occlusive disease?

Atherosclerotic plaques develop slowly and and increased prevalence in elderly and people with diabetes

4

What is a manifestation of atherosclerotic occlusive disease in PVD?

Intermittent claudication which is ischemic pain

5

How does the body compensate for the atherosclerotic plaque in PVD

Vasodilation, collateralization, anaerobic metabolism

6

In PVD, why is vasodilation a minimally successful compensation done by the body?

Because of the "hardened" arteries

7

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

8

What occurs if there is no treatment for PVD?

Ulceration and gangrene occur then amputation is necessary

9

Where does atherosclerotic occlusive disease most commonly occur?

In the arteries in the legs
