Abstract： 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. Results Compared with the control group, the patients in DVT group showed significantly increased serum levels of D-dimer (29.17±38.67 vs 0.21 ±0.27 μg/mL), FIB (3.66± 0.95 vs 3.32±0.65 g/L) and FDP (76.14±131.48 vs 1.08±0.73 μg/mL) before CDT (P<0.05). Based on the effect of CDT, the patients with DVT were divided into recanalization group (n=34) and failed recanalization group (n=16), and the patients with recanalization had significantly increased serum concentration of D-dimer and FDP (P<0.05) and decreased FIB level (P<0.05) compared with those with failed recanalization at 24 h of CDT. D-dimer, FDP, and FIB showed no significant changes in the patients with failed recanalization after the procedure (P>0.05). Correlation analysis showed that serum D-dimer (r=0.66, P< 0.05) and FDP (r=0.50, P<0.05) at 24 h of the procedure were positively correlated with the outcomes of CDT. Conclusion Serum levels of D-dimer, FIB and FDP are important indicators for evaluating and predicting the effectiveness of CDT in patients with acute DVT.
