Venous ulcers and assessment
Although the ulcer may appear venous, the assessment process is
aimed at eliminating an arterial component, so that safe and
effective treatment can be offered. If an arterial pathology is detected,
then a referral to the vascular surgeon is required.
Doppler (ABPI) Lie the patient flat for at least 10 minutes Apply appropriate size cuff around upper
arm; locate brachial pulse; apply gel and
hold Doppler probe at angle of 450:inflate until pulse disappears, deflate and record the point at which the pulse returns; = brachial systolic reading
Repeat on the other arm and record the highest reading of the two, to calculate ABPI
Doppler (ABPI) continued Place cuff around ankle, above malleoli (any
higher up the leg can give a higher reading) Locate DP; apply gel; hold Doppler probe at
angle of 450 :inflate until pulse disappears, deflate and record the point at which the pulse returns; repeat for PT; Record the highest pressure
Repeat process for other foot: Record the highest pressure
Divide the highest ankle pressure by the highest brachial pressure to give your ABPI
Ankle Brachial Pressure Index 1 – 1.2….Normal0.9……….Mild arterial effect (safe to compress)< 0.7 …..Significant arterial disease< 0.6…….Severe PVD>1.3………Refer to vascular specialist
> 1.3; If the arteries of the leg are calcified or hardened, they may fail to occlude even at high pressure. The systolic ankle pressure may then
appear higher, and a false high reading recorded. Other conditions giving higher readings are renal
disease and gross oedema
