DVT affects as many as 2 million Americans every year. The majority of patients are treated medically, with anticoagulation being the mainstay of therapy to promote thrombus resolution and prevent propagation and embolization. Because phlegmasia is a rare condition, its incidence is unknown. The best estimate is derived from case series of patients treated for extensive DVT. In more recent series, 10-20% of patients undergoing thrombolysis with possible stenting for extensive DVT presented with phlegmasia. [7, 8, 9]

The prevalence is thought to be slightly higher in men than in women, with a male-to-female ratio of 1.5:1. [10]
