Isolated thrombosis of plantar veins. Case report.

The author reports a case of isolated thrombosis of plantar veins, a rare finding in the international medical literature, in a patient who had a previous knee arthrocentesis and a strict localized bandage. The clinical aspect of perimalleolar-podalic (mainly plantar) oedema, with localized pain, was followed by colour flow duplex investigation, which is considered the fundamental and most useful means to achieve the diagnosis and to perform an adequate follow-up. Pharmacological therapy of such kinds thrombosis may be of an antithrombotic or anticoagulant nature, always associating elastic compression. Aethiopathogenesis of this localized thrombosis is still uncertain, but probably in situ mechanical compressions may play an important role.
