ICD-9-CM Code



671.4 Deep venous thrombosis


Epidemiology & Demographics



• DVT is the third most common cardiovascular disease after acute coronary syndromes and stroke.

• It affects approximately 2 million Americans per year.

• Almost 40% of patients with DVT without symptoms of pulmonary embolism (PE) have signs of PE on lung scanning.

• Risk factors include underlying hypercoagulable state, trauma, or immobilization.


Clinical Presentation



• The patient may have subacute onset of pain, swelling, and erythema of the affected limb.

• Trauma or immobility of the affected extremity (e.g., fracture with casting)

• Underlying hypercoagulable state

• Trauma to the vein, including venous catheterization


Physical Examination



• The most trustworthy of signs and symptoms include the following:
image Localized tenderness along the distribution of the deep venous system

image Thigh and calf swollen (should be measured)

image Calf swelling by more than 3 cm compared with the asymptomatic leg (measured 10 cm below the tibial tuberosity)

image Pitting edema in the symptomatic leg only

image Dilated superficial veins (nonvaricose) in the symptomatic leg only

image Erythema
