Peripheral Vascular Examination

This article is a stub. Please help WikiMSK by expanding it.

Peripheral vascular disease can mimic musculoskeletal causes of pain. Most patients do not have intermittent claudication but have atypical leg symptoms or no symptoms at all.[1][2] Therefore is important for the Musculoskeletal Medicine Doctor to know how to perform a competent peripheral vascular examination.

Special Tests

Ankle Brachial Pressure Index

  • The patient should lie in a supine positive for 5 minutes before measurement
  • Upper limb measurement
    • Place the cuff in the usual fashion
    • Inflate the cuff to 20 mmHg above systolic arterial pressure
    • Record the pressure using a doppler device by placing it over the brachial artery
  • Lower limb measurement
    • Place the cuff above the malleoli
    • Place the doppler probe over the posterior tibial and dorsal pedal arteries
  • The ABP is the highest systolic pressure value of the lower limbs divided by the higher of the brachial artery pressures
  • Interpretation
    • โ‰ค0.9 is PAD
    • 0.91 - 1.0 is borderline
    • >1.00 - 1.4 is normal
