Thrombolysis and fibrinolytic parameters during heparin treatment of deep vein thrombosis. 1985

S Schulman, and S Granqvist, and B Wiman, and D Lockner

Thirty-nine patients with symptomatic, venographically verified deep vein thrombosis (DVT) were studied during treatment with heparin in order to investigate the correlation between the venographic changes and parameters of heparin therapy or fibrinolytic components. Venograms were scored with a 40-grade scale, and after one week a significant improvement with an average reduction of the thrombi of 17% was observed. No statistically significant correlation was found between reduction of thrombus size and duration of heparin treatment, total amount of heparin administered, mean levels of APTT, plasmin-alpha 2-antiplasmin complex (PAP), tissue plasminogen activator (t-PA) antigen or t-PA-inhibitor. Only a short history of the thrombus was significantly correlated to thrombolysis. The concentrations of PAP and t-PA-inhibitor were not influenced, while that of t-PA antigen showed a significant increase during heparin infusion. Even if statistically significant correlations were not obtained, the patients with pronounced thrombolytic effect had high PAP-levels. Furthermore, patients with high t-PA-inhibitor levels had no lysis. The results suggest, that also other factors than plasminogen dependent fibrinolysis are of importance for the thrombolytic effect.

D005342	Fibrinolysis	The natural enzymatic dissolution of FIBRIN.	Fibrinolyses
D006493	Heparin	A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.

D013918	Thrombin Time	Clotting time of PLASMA mixed with a THROMBIN solution. It is a measure of the conversion of FIBRINOGEN to FIBRIN, which is prolonged by AFIBRINOGENEMIA, abnormal fibrinogen, or the presence of inhibitory substances, e.g., fibrin-fibrinogen degradation products, or HEPARIN. BATROXOBIN, a thrombin-like enzyme unaffected by the presence of heparin, may be used in place of thrombin.
