Peripheral art disease Flashcards
1
Q
general review of PAD
A
- usually in legs
- art. insuff. results when demand exceeds supply
- ischemia results
2
Q
5 features of athero physiology
A
- progressive
- eccentric
- multifactorial
- in media of A
- heterogernous
3
Q
5 major risk factors for PAD in order
A
- smoking
- DM
- age
- HT
- cholest
4
Q
what does PAD affect
A
SYSTEMIC
5
Q
** what is ACUTE ischemia
A
- Sx that dev. quickly and progress
- SUDDEN leg pain
- VERY VERY severe pain
6
Q
what causes acute ischemia - 4
A
- embolus forms in one region and travels
- thrombosed A
- trauma
- acute on chronic
7
Q
6 Ps of acute ischemia
A
Pain Pallor Paralysis Paresthesias Pulselessness Polar
8
Q
***2 most important Sx of acute ischemia
A
Paralysis - movement
Paresthesias - sensation
9
Q
** what does disrupted movement or sensation mean
A
- threatened extremity
- NEED TO ACT NOW
10
Q
what are 2 presentation of chronic PAD
A
- claudication
- critical ischemia
- rest pain
- night pain
- non-helaing wounds or ulcers
11
Q
what is presentation of claudicatiokn
A
- pain (esp calves) with excercise
- predictable - always same amount of ecercise
- goes away with rest
12
Q
what is risk in claudication
A
low risk of limb loss
- depends on degree of the impairment
13
Q
what is Sx of critical ischemia
A
- rest pain
- night pain
- non-helaing wounds or ulcers
14
Q
what is risk of critical ischemia
A
HIGH risk of limb loss
- also a marker of severs athero
- likely to die in 5 years
15
Q
what is importance of pulses
A
the harder they are, the more likely they are to have PAD
