Superficial thrombophlebitis can occur spontaneously, especially in the lower extremities in the GSV, or as a complication of medical or surgical interventions. Although the etiology is frequently obscure, superficial venous thrombosis is most often associated with one of the components of the Virchow triad; ie, intimal damage (which can result from trauma, infection, or inflammation), stasis or turbulent flow, or changes in blood constituents (presumably causing increased coagulability). (See Etiology.)
