1

What causes peripheral vascular disease?

atherosclerosis causing stenosis of the arteries

2

Chief feature of PAD?

intermittent claudication

3

What is intermittent claudication?

pain/cramping within the calf, thigh or buttock after walking a short distance

4

If claudication pain occurs at rest and is relieved by hanging legs over the side of the bed, what is the most likely diagnosis?

critical limb ischaemia

5

Claudication within the calf suggest disease within which artery?

femoral

6

Claudication within the buttock suggests disease within which arteries?

iliac

7

Other signs of critical limb ischaemia

ulceration and gangrene

8

Signs of peripheral arterial disease?

absent pulses; cold, white legs; atrophic skin; punched out ulcers; postural dependent colour change; cap refill of >5 secs

9

Tests for peripheral arterial disease?

ABPI - 1-1.2 normal; 0.5-0.9 is ischaemic; ,0.5 is severely ischaemic; Doppler imaging; CT angiography

10

4 stages of PAD

1 - asymptomatic, 2 - intermittent claudication, 3 - ischaemic pain at rest, 4 - ulceration/gangrene

11

Intervention for intermittent and aysmptomatic claudication

quit smoking, increase exercise - supervised, vasoactive drugs, anti-platelet drugs (i.e. clopidogrel)

12

Intervention for more severe and limb-threatening PAD

percutaneous transluminal angioplasty, surgical reconstruction, amputation

13

6 Ps of acute limb ischaemia

pale, pulseless, painful, paralysed, paraesthetic (pins and needles), perishingly cold

14

Onset of fixed mottling in acute limb ischaemia implies?

irreversibility

15

Acute limb ischaemia requires treatment within...

4-6 hours

16

Causes of acute limb ischaemia

thrombosis, embolis, graft/angioplasty occlusion, trauma

17

what is gangrene?

death of tissue from poor vascular supply

18

dry gangrene is...

death of tissue in the absence of infection

19

wet gangrene is...

death of tissue and infection associated with a discharge occurring together

20

necrotising fasciitis is...

rapidly progressive infection of the deep fascia causing necrosis of subcutaneous tissue
