sunset foot?
critically ischaemic foot may appear red and ‘healthy’. This is known as a ‘sunset’ foot and occurs due to maximal skin capillary dilatation and is often mistaken for cellulitis
what causes sunset foot in critical ischemia?
- due to SNS activiation to get blood to peripheries so there is perm vasodilation -> hot foot - sleeping in chair with foot hanging out

appearance of a venous ulcer?
- shallow wet appearance of a venous ulcer
- rusting of skin - hemosiderin deposition
- capillary perfusion drives RBCs into subcutaneous space where they become brown caused by venous hypertension
venous ulcer - scarring?
