2 - Punched out and deep
3 - Tight, dry skin
4 - Hairless legs
5 - Necrotic but dry ulcer
6 - Normal/high ABPI

Question 12

If a patient has a mixed venous and arterial ulcer, which is most important to fix?

Answer 12

• arterial
• then can focus on venous

Question 13

Should compression be avoided in arterial and venous ulcers?

Answer 13

• avoided in arterial but not venous
• Graduated compression bandaging exerting around 35 – 40 mmHg at the ankle is the mainstay of treatment of active venous ulceration
• diminishes leg vein distension and stasis by cutting down on inflammation
• diminishes oedema and improves tissue perfusion and transfer
• improves overall venous function by improving venous pump function
• keeps skin dry and avoids maceration of skin
