Abstract:
:Five criteria for poor response to a 20 min venous occlusion test were applied to 58 patients 3 months or more after acute deep vein thrombosis (DVT). The criteria were arbitrarily defined as the last 5 percentiles of response distributions in an age- and sex-matched healthy control group of 51 subjects. The criteria were: 1. euglobulin clot lysis time after venous occlusion greater than or equal to 140 min; 2. t-PA activity after venous occlusion less than or equal to 0.04 IU/ml; 3. increase in t-PA antigen above resting value less than or equal to 2-fold; 4. ratio between t-PA antigen increase and resting PAI activity less than or equal to 0.5 ng/IU; 5. PAI activity after venous occlusion greater than or equal to 6 IU/ml. The last criterion of poor response was the only one that was significantly more frequently reached by patients than by controls: 28% (p less than 0.005) of all DVT patients and 35% (p less than 0.005) of the subgroup with idiopathic DVT (N = 34) were found to be poor responders. The percentage of poor responders according to the other four criteria was 7-11% in all patients and 9-15% in the subgroup with idiopathic DVT and thus was not significantly higher than in controls (5% by definition). It was concluded that residual PAI activity after venous occlusion might be a useful criterion for prospective studies on recurrence of DVT.
