Answer

The exact number of patients who have IVCT remains elusive because of the clinical variability in presentation. By compiling information from several epidemiologic studies that investigated DVT prevalence, the following US estimates can be generated:

  • The DVT rate in the United States is 60-180 cases per 100,000 population per year
  • The frequency of IVCT in patients with DVT is 4-15%
  • Annually, 165,000-493,000 cases of DVT occur
  • Between 6600 and 74,000 cases of IVCT occur each year

These numbers are estimates generated from various population-based studies. Various groups within the general population have a greater propensity for IVCT (see Etiology).
