Using a mercury plethysmograph, the venous resistance (a novel venous parameter) is determined separately for the veins of the thigh and lower leg, using the Brakkee and Kuiper (1982) method. In a retrospective study of acute and subacute thrombosis, the authors detected sensitivity of 91 and 36% respectively in proximal and distal thromboses. Specificity was 100 percent. Although differences from the control grop were detected, it would seem that the presence of a varicose trunk or lymphedema does not affect either sensitivity or specificity. |
