Lower extremity symptoms	Signs
Swelling	Edema or swelling with a difference in calf or thigh circumference^*¶

Erythema	Dilated superficial veins
	Homans sign (calf pain on passive dorsiflexion of the foot)^Δ

This table describes common clinical presentations of acute DVT. Symptoms are usually unilateral but can be bilateral.

DVT: deep venous thrombosis.

* A measurable difference in calf or thigh circumference is the most useful finding and should raise the suspicion for DVT.

¶ Manifestations may be localized to the calf with distal vein DVT and may involve the whole leg with proximal vein DVT. Massive swelling of the proximal leg and buttock pain may suggest iliac vein DVT or early phlegmasia; reduced or absent pulses suggest associated arterial insufficiency.

Δ This sign is unreliable for the presence of DVT.
