Signs

• The patient's superficial veins may be dilated and a "palpable cord" may be felt in the affected leg.

• The patient may experience unilateral leg edema with measurable difference in leg circumference, erythema, increase in warmth, tenderness with palpation of calf muscles.

• The patient may experience pain in back of the knee in the affected leg when the examiner dorsiflexes the foot while the knee is slightly bent (Homan's sign).

NOTE: The physical exam signs can be unreliable. Homan's sign (an increased resistance to foot dorsiflexion without pain or discomfort as criteria for the positive test)

can also be unreliable.
