Upper limb

Inspection

  • cyanosis/pallor
  • hair loss
  • shiny skin
  • ulcerations
  • dystrophic nails
  • muscle wasting

Palpation

  • measure the blood pressure
  • skin temperature (compare bilaterally)
  • capillary refill time
  • Pulses:
    • Abdominal Aorta - palpate for aneurism
    • radial, ulnar
    • brachial - in antecubital fossa, medial to biceps tendon

Auscultation

  • bruits:
    • abdominal aorta
    • renal (both anterior and posteriorly)

Provocative Tests

  • Allen's Test for adequacy of circulation to hand
    • occlude both the radial and ulnar arteries → patient to make fist
    • open hand → release ulnar artery → watch for reperfusion of the palm
      • repeat above for radial artery
  • Ankel to Brachial Index
  • compares the palpated systolic BP in the arm to that of the ankle
    • with patient supine, place the center of the bladder posterior and ~ 3 cm above the medial malleolus
      • resting ABI < 1 is abnormal
      • < 0.95 → significant narrowing of blood vessels in the legs, ↑ CV risk
      • < 0.8 → intermittent claudication
      • < 0.4 → claudication may occur at rest
      • < 0.25 → severe limb-threatening PAD

Lower Limb

Inspection

  • same as UL: cyanosis/pallor, hair loss, shiny skin, ulcerations (especially on the heel), dystrophic nails
    • edema (pitting or non)

Palpation

  • skin temperature (compare bilaterally)
  • Capillary refill time
  • Pulses:
    • femoral - midway between the pubis and ASIS
    • popliteal - inferior lateral portion of the popliteal fossa (leg slightly flexed)
    • posterior tibial - inferior posterior border of medial malleolus
    • dorsalis pedis - upper 1/3 of dorsal foot, lateral to EHL
  • Radial Femoral Delay
    • coarctation of aorta

Auscultation

  • bruits:
    • femoral
    • popliteal

Provokative Tests

Bueger’s test

  • raise legs to 45° x 1 min → max blanching of skin
  • have patient sit with both legs dangling down
    • pinkness should return in < 10 s
  • look for dusky rubor (reactive hyperemia)

DeWeese’s test

  • disappearance of previously palpable distal pulses after walking

Arterial vs. Venous Insufficiency

Arterial Insufficiency Venous Insufficiency
Pain claudication
Pulses ↓
Color pale, dusky red on dependency
Temp ↓
Edema marked
Skin trophic skin chagnes, thick nails brown pigmentation around ankle, stasis dermatitis
Ulcers very painful non painful
