Distal deep vein thrombosis of the lower limbs: A controversial problem

The frequency of the distal deep vein thrombosis is between 20 and 50% of all deep lower limb thrombosis, and has the same risk factors as proximal and pulmonary embolism, and with 50% lower risk of recurrence. Its natural history is not well-known, and may explain the debate about its importance. The most common complication is post-thrombotic syndrome. The echo-Doppler is the most used diagnostic method. D-dimer alone does not exclude thrombosis, is not useful predictors of recurrence, and is associated with post-thrombotic syndrome. Soluble P-selectin, combined with the Wells index is an excellent diagnostic test. Anticoagulation varies between 3 months and indefinitely depending on whether the thrombosis is provoked or idiopathic. If cancer, it is recommended to continue treatment until 6 months after cure or complete remission. (C) 2015 SEACV. Published by Elsevier Espana, S.L.U. All rights reserved.
