Objective  To investigate the feasibility and efficacy of transcatheter directed thrombolysis (TDT) approach in treatment for deep venous thrombosis (DVT) of lower limbs and as compared with trans-dorsal pedis vein thrombolysis (TPVT) approach.
Methods  The clinical data of 437 patients with acute DVT (184 males and 253 females) at the age of (43±12) years (range 19-76 years) from July 2008 to January 2012 in the First Affiliated Hospital of Zhengzhou University were analyzed retrospectively. Patients in the group TDT received TDT were 293 cases, 32 inferior vena cava filters were implanted. Patients in the group TPVT received TPVT were 65 cases, 4 inferior vena cava filters were implanted.
Results  The resolution time of thrombus in the group TDT was shorter than that in the group TPVT (6 d versus 9 d, P<0.05). The circumference difference of leg or upper leg before and after treatment in the TDT group was significantly greater than that in the TPVT group (P<0.05). The rate of venous patency was (65.2±15.4)% and preservation rate of valvular function was (78.2±12.6)% in the group TDT, and which was (63.8±16.3)% and (91.1±10.7)% in the group TPVT, respectively. The differences of venous patency rate was not statistically significant(P>0.05) between two groups, but the prevervation rate of valvular function was significant difference (P<0.05) .Hematomas in 3 cases and gross hematuria in 4 cases were observed, and displacement of inferior vena cava filter occurred in 1 patient in the group TDT. The gums bleed or gross hematuria in 5 cases were observed in the group TPVT.
Conclusions  Both TDT and TPVT can effectively relieve symptoms. TDT can shorten the course of disease, but it
increases functional damage of the deep vein valvular.
