In medicine, calf vein thrombosis is deep venous thrombosis (DVT) of the infrapopliteal calf veins.[1][2] These veins are also called distal calf veins. The trifurcation of the popliteal vein is about 10 cm distal from the mid-patella.[3] Distal DVTs are more common than proximal DVTs in studies using venography[2] but not in studies using ultrasonography[4]. Many distal DVTs are assymptomatic.[5]

Diagnosis

The d-dimer test may not reliably detect thromboses of the calf vein with sensitivity of about 65%.[2]

Treatment

For patients with symptomatic calf-vein thrombosis, compression stockings along with anticoagulation may prevent recurrences.[6]

Prognosis

While unusual, case reports exist of pulmonary embolism from calf vein thrombosis.[7]
