Aim and Objective: To evaluate the efficacy and safety of Chinese herbal medicines for
promoting blood circulation and removing blood stasis (PBCRBSM) for preventing deep venous
thrombosis (DVT) after total hip arthroplasty (THA).
Materials and Methods: The databases were searched for studies comparing the preventive abilities
of PBCRBSM and Western medicine, such as low molecular weight heparin (LMWH), rivaroxaban,
and aspirin, as well as for randomized controlled trials on DVT after THA. Data were analyzed
using RevMan 5.3 software.
Results: A total of 3254 randomized controlled trials were included, including 1630 cases in the experimental
group and 1624 cases in the control group. Meta-analysis showed that compared with
Western medicine, PBCRBSM reduced the incidence of DVT (OR=0.38, 95% CI [0.30, 0.48], P <
0.001); prolonged activated partial thromboplastin time (APTT) (SMD=0.44, 95% CI [0.35, 0.53],
P < 0.001); reduced D-dimer (SMD=-0.75, 95% CI [-0.84,-0.65], P < 0.001), FIB (SMD=-0.61,
95% CI [-0.72, -0.50], P < 0.001), blood viscosity (P<0.01), circumference difference in lower extremities
(P<0.01), venous blood flow velocity (SMD=0.97, 95% CI [0.77, 1.16], P < 0.001), and
drainage volume (SMD=-1.53, 95% CI [-1.71, -1.35], P < 0.001); and reduced adverse reactions
(OR = 0.32, 95% CI [0.19, 0.56], P < 0.001). There was no significant difference in prolonging prothrombin
time (PT) between traditional Chinese medicine and Western medicine (SMD = 0.07,
95% CI [-0.0.01). 3, 0.16], P > 0.05.
Conclusion: PBCRBSM is an effective method for preventing DVT after THA and has fewer adverse
