[Clinico-epidemiological study of patients with phlebolymphatic diseases admitted to the hospitals of the Piedmont region 1976-1979. IV. Analysis of thrombophlebitis].

In the 1976-79 period, 8040 cases of thrombophlebitis, equivalent to 0.17% of the population, were admitted to Piedmontese hospitals, an average of 1 admission every 4 hours and 3 minutes. The present study revealed a numerical and percentage increase with increasing age. The figures per age group from each individual clinic revealed two large areas in the East and South West of the Region where phlebitis cases were numerically lower than the regional average. In other areas figures were higher than estimated, while still others produced statistically insignificant figures. An interpretation of these results is attempted.
