DEZOTTI, Nei Rodrigues Alves et al. Venous hemodynamic study by air plethysmography in the pre- and postoperative period of lower limb varicose veins. J. vasc. bras. [online]. 2009, vol.8, n.1, pp.21-28. ISSN 1677-5449.  http://dx.doi.org/10.1590/S1677-54492009000100004.

Background: Surgical treatment of primary varicose veins of the lower limbs might contribute to venous stasis relief by preventing evolution of the venous disease to worse severity stages. Objective: To study venous hemodynamic changes in patients with primary varicose veins of the lower limbs during the pre- and postoperative period using air plethysmography. Method: Sixty-three lower limbs of 39 patients (35 females and four males, mean age of 46.3 years) were evaluated. They were all operated at Hospital das Clínicas, Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, between January 2001 and December 2004. Lower limbs were classified according to the CEAP classification: clinical criteria = C2 to C6 (C2 = 6, C3 = 32, C4 = 15, C5 = 7 and C6 = 3), etiologic criteria = Ep, anatomic criteria = As, and pathophysiological criteria = Pr. The patients were submitted to pre- and postoperative clinical examination, preoperative duplex scan and pre- and postoperative air plethysmography. Results: Improvement in venous hemodynamics was observed after surgery, confirmed by reduction in the venous filling index and residual volume fraction and increase in the ejection fraction in the lower limbs submitted to varicose vein surgery. Conclusion: Superficial varicose vein stripping contributed to venous stasis relief and provided appropriate treatment, preventing pathophysiological evolution of chronic venous disease independently of clinical severity.
