Clinical characteristics and outcomes of patients with superficial venous thrombosis at multiple sites simultaneously

Background: Superficial venous thrombosis (SVT) results from thrombus formation within a superficial vein that is associated with inflammation of the surrounding tissue, and classically presents with pain, tenderness, induration, and/or erythema in the form of a palpable cord. Although traditionally considered a local, benign disorder, recent studies demonstrate that patients with SVT are at significant risk for deep vein thrombosis (DVT), pulmonary embolism (PE), and other venous thromboembolic (VTE) events.
