  • Title: Hemodynamic assessment of chronic venous insufficiency.
    Author: Alam S, Sakurai T, Yano T, Shionoya S, Hirai M.
    Journal: Jpn J Surg; 1991 Mar; 21(2):154-61. PubMed ID: 2051660.
    Abstract:
    To study the pathogenesis of chronic venous insufficiency (CVI), photoplethysmography and strain-gauge plethysmography were simultaneously performed in 84 patients. Of the 128 limbs studied, 24 were normal, 64 had primary varicose veins and 40 had post-thrombotic syndrome. Venography was also performed in all patients. The results of this study indicate that reflux in the superficial veins is the main pathophysiology involved in the development of CVI, though incompetence of the perforators and deep veins plays some role. In post-thrombotic syndrome, however, CVI is mainly a sequel of deep venous incompetence, the condition being complicated by incompetent perforators and superficial venous reflux.
