Vascular disease Flashcards
(11 cards)
where does atherosclerosis happen?
Large and medium sized conduit arteries
turbulence at bifurcations =important factor
coronary, carotid and lower limb arteries
Describe chronic lower limb ischaemia
often bilateral
collateral circulation can develop over time
Fontaine classification of limb ischaemia
asymptomatic
intermittent claudication
ischaemic rest pain
ulceration/gangrene = critical ischaemia
Signs of critical ischaemia
gangrene, ulceration and foot pain at rest
Describe acute limb ischaemia
surgical emergency
complete occlusion has occurred
very painful
6Ps
Decribe Thrombobangittis obliterans
Inflammatory process (small and intermediate arteries)
Men heavy smokers
Autoimmune reaction to smoke
ulcerations and gangrene
Describe varicose veins
persistent distended superficial veins
veins under pressure (up to 5-10X as much when person is erected)- pregnancy, pelvic are tumours
loss of supporting muscle/tissue
familial
Describe PAD
Most common
fermoral, popliteal, tibial and fibular, aorta and iliac
Claudication
smooth shinny skin, no hair, increased toe nail thickness , small circular deep ulcers
When is an acute peripheral occlusion like to occur and how?
Emboli
Post MI
Describe PVD
Chronic venous insufficiency irregular shape, superficial No IC normal nails Varicose eczema (stasis dermatitis) Incompetent valves, pooling, DVT Normal pulses, brown patches, oedema
How would you diagnose PAD?
Ankle, brachial index
brachial systolic vs systolic
BP of ankle is t least 90% of arm
