Embolectomy (BAE)
What is a complication of acute limb ischaemia?
Reperfusion injury
How can diabetes affect ABPI?
Calcification and stiffening of arteries
What are some symptoms of chronic limb ischaemia?
Intermittent claudication (location/ distance varies)
Rest relief (critical is rest pain whereas chronic is rest relief)
Loss of hair and toenails
Arterial ulcers
How can you diagnose a chronic limb ischaemia?
Bloods
ABPI
Duplex scan
Angiography
How can you surgically treat chronic limb ischaemia?
Vscular by-pass e.g. using a reverse saphenous graft to connect common femoral to popliteal by-passing superficial femoral.
What happens in critical limb ischaemia?
Rest pain
What is the SFJ and SPJ?
The saphenous femoral junction and saphenous popliteal junction which drains blood from superficial to deep.
What are varicose veins?
Dilated tortuous superficial veins which permit reverse flow. Causes are valvular failure which can be primary/ idiopathic or deep venous osbtruction
Common in both males and females. 50% over 50
Many treated conservatively
Complication like uulcers could mean hosiery or surgery.
