title: [Sequelae of venous thrombosis. Incidence in of the post-thrombosis syndrome after 5 years].
abstract: The authors report on an epidemiological study carried out in Basle, Switzerland, which prospectively included 341 consecutive patients (226 men, 115 women, mean age 52 +/- 16 years) who had developed deep venous thrombosis evidenced by phlebography. The treatment of the acute phase most often consisted in thrombolysis, conventional heparin being reserved for the contra-indications of thrombolysis. A second phlebographic examination allowed dividing up the series into two groups, ie. positive and negative, according to the presence or absence of a complete or partial return of patency. Each group was subdivided according to the location and extension of the thrombosis. Both groups (positive vs. negative) are different as regards the location and extent of the thrombosis. The selective comparison of both groups according to the objective subdivision demonstrated: the absence of post-phlebitis disease in sural phlebitis; the same risk of post-phlebitis disease in thrombosis extending to 4 levels, whether patency was restored or not; lower incidence of post-phlebitis disease in the positive group for single -, two - or three-level phlebitis. Leg ulcers occur within an average of 5.5 +/- 2.1 years after the acute episode in 6.7% of all patients. Complete return of patency is obtained in 23% of cases only.
