Overview

The physical examination may be completely normal in patients with DVT. A high degree of suspicion is necessary for early identification of venous thrombosis, as sometimes these patients are admitted with a different complaint and a thorough physical exam gives a clue to the diagnosis.

Physical Examination

Vitals

Temperature, blood pressure, heart rate and respiratory rate may all be within normal range.

Extremities

• One of the most significant part of the physical exam in a patient with a suspected DVT is the measurement of the size of both legs at the same point (usually measured vertically from the knee joint), to assess for differences. If a difference is detected, and there is suspicion of DVT, further tests should be conducted. The complete exam of the extremities should include assessment of all the following:
  • Unilateral calf or thigh tenderness
  • Unilateral calf or thigh pitting edema
  • Unilateral calf or thigh swelling
  • Difference in calf diameters > 3 cm (the calf circumference is measured 10 cm below the tibial tuberosity)
  • Difference in thigh diameters (the thigh circumference is measured 10-15 cm above the patella)
  • Unilateral calf or thigh warmth
  • Unilateral calf or thigh erythema
  • Palpable cord (a thickened palpable vein suggestive of thrombosed vein)
  • Dilatation of unilateral collateral superficial veins
  • Localized tenderness upon palpation of the deep veins
    • Posterior calf
    • Popliteal fossa
    • Inner anterior thigh
• The physical exam should also include assessment of the following:
  • Generalized edema (suggestive of nephrotic syndrome)
  • Ascites (suggestive of Budd Chiari syndrome, that is hepatic vein thrombosis)
  • Hepatomegaly (suggestive of Budd Chiari syndrome, that is hepatic vein thrombosis)
