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] The distal veins are the posterior tibial vein, anterior tibial vein, and peroneal vein. Thromboses occur more often in the peroneal and posterior tibial veins than the anterior tibial veins.[1]
Distal DVTs are more common than proximal DVTs in studies using venography[2] but not in studies using ultrasonography[4]. Many distal DVTs are asymptomatic.[5]
Diagnosis
The d-dimer test may not reliably detect thromboses of the calf vein with sensitivity of about 65%.[2]
Comprehensive duplex ultrasonography of the whole leg may adequately indicate patients at low risk of short term complications over three months.[4] Simplified compression ultrasonography limited to the trifurcation of the popliteal vein may need repeating in 5 days.[3]
Treatment
Treatment and follow-up options have been reviewed.[6]
For patients with symptomatic calf-vein thrombosis, compression stockings along with anticoagulation may prevent recurrences.[7]
Prognosis
While unusual, case reports exist of pulmonary embolism from calf vein thrombosis.[8]
