[Clinical significance of monitoring coagulation- and fibrinolysis-related indexes during catheter-directed thrombolysis for acute lower-extremity deep venous thrombosis].

Objective: To investigate the patterns of changes in serum levels of of D-dimer, fibrinogen (FIB) and fibrin degradation product (FDP) during catheter-directed thrombolysis (CDT) in patients with acute lower-extremity deep venous thrombosis (DVT) and explore their clinical significance.

Methods: From June, 2014 to June, 2015, 50 patients with acute lower-extremity DVT received CDT. The serum concentrations of D-dimer, FIB and FDP were measured before, during and after CDT in all the subjects, with 50 healthy subjects serving as the control group.
