Current management of isolated soleal and gastrocnemius vein thrombosis.

Thrombi of the soleal and gastrocnemius veins of the leg remain incompletely characterized in terms of the appropriate treatment algorithm to follow. Although they are anatomically located below the level of the fascia, making them "deep" vein thrombi, their natural history is unclear with respect to propagation and embolization. Varying treatment suggestions have been proposed, from full-dose anticoagulation to "watchful waiting" with repeated duplex examination, with none rising to the level of accepted scientific evidence. Herein, we present the current literature citing the differing opinions and data that have confused the subject.
