Flashcards in Peripheral arterial disease Deck (18)
2 types of classification scheme for peripheral arterial disease
Imaging tests to do for peripheral arterial disease? (give order)
1. Duplex USS
2. CT/MR angiogram
Bedside investigation for peripheral arterial disease?
Ankle Brachial Pressure Index
What is the ABPI score associated with intermittent claudication?
ABPI < 0.8
What is the ABPI score associated with Critical Limb Ischaemia
ABPI < 0.3
6 P's associated with Acute limb Ischaemia
2 examples of tissue loss in Critical limb ischamia
Normal ABPI range?
0.9 - 1.1
Risk factors for chronic lower limb ischaemia
SSx of chronic limb ischaemia (intermittent claudication)
Severe cramp which resolves on stopping walking
Cold lower limbs
Absent or diminished peripheral pulses
SSx of critical limb ischaemia
Dependency rubor (When raising feet in Bueger’s test, colour is white and placing feet back on the ground turns red again)
Tissue loss --> ulceration/gangrene
Criteria for critical limb ischaemia
Fulfil just 1 criterion:
Requiring opiate analgesia and/or tissue loss (ulceration or gangrene) present for more 2 weeks
ABPI < 0.5 or ankle systolic pressure < 50mmHg
1st line imaging for peripheral arterial disease?
Duplex USS (CT/MR angiogram if stenosis higher up)
Preventive Mx for PAD?
Clopidogrel 75mg OD (1st line)
Aspirin 75mg OD (2nd line)
Symptomatic Mx for PAD?
Naftidrofuryl oxalate (1st line)
Cilostazol (2nd line)
IV Iloprost used if patient unsuitable for surgery
Indications for amputation?
Procedure for chronic/critical limb ischaemia?
Percutaneous balloon angioplasty +/- endovascular stent
--> if have lifestyle limiting symptoms
--> medical and lifestyle treatments fail
