Peripheral vascular disease I & II Flashcards
What is intermittent claudication?
blood reaching exercising muscle is insufficient
Define claudication
Muscle ischaemia
What are the symptoms of intermittent claudication
patient is pain-free at rest, but after periods of exercise pain develops in affected limb, relieved by further rest
What are the risk factors of intermittent claudication?
> male gender > age (per 10 years) > diabetes > smoking > hypertension > hypercholesterolaemia > fibrinogen > alcohol
What are the non-invasive investigations of PVD?
o measurement of ABPI
o duplex ultrasound scanning
What is the normal ranges of ABPI?
> normal 0.9-1.2
claudication 0.4-0.85 (-1.0)
0-0.45
What are the invasive investigations of PVD?
> magnetic resonance angiography
CT angiography
catheter angiography
What are the guardian therapies of PVD?
o SMOKING o lipid lowering o antiplatelets o hypertension Rx o diabetes Rx o life-style o walking will develop collateral circulation
What are the guidelines for exercise for improvement of symptoms?
1 hour per day to 30 mins 3 times per week for a minimum of 6 months
Which drugs are used in PVD?
cilostozol
What are some invasive modes of PVD treatment?
o angioplasty/stenting o surgery - endartectomy - bypass - anatomic - extra-anatomic > prosthetic (dracon, ePTFE) > vein
What are some symptoms of critical limb ischaemia?
rest pain= toe/fore foot ischaemia o lying o sleeping -worse at night -helped by sitting and putting the leg in a dependant position -helped by getting up and walking about
What is a side effect of ischaemia?
Ulcers/gangrene
What are the two major risk factors for critical limb ischaemia?
Smoking
Diabetes
What are the 4 treatments of critical limb ischaemia?
- Realistic Expectations
- Analgesia
- Angioplasty / Stenting
- Surgical reconstruction / amputation
