BackgroundDespite the usefulness of traditional Chinese medicine (TCM) in the treatment of lower deep vein thrombosis (DVT), there is no consensus on safety and efficacy. We aim to systematically evaluate the safety and efficacy of TCM combined with Rivaroxaban in the treatment of lower limb DVT.MethodsAn online search of databases such as Cochrane Library, Embase, Pubmed, and Web of science, as well as CBM, China Science and Technology Journal Database, China Knowledge Network (CNKI) and Wanfang Data (from inception to July, 2021) was performed. All published clinical randomized controlled trials (RCTs) were screened manually, evaluated for quality and considered for meta-analysis using RevMan 5.3.ResultsNine RCTs with a total of 730 cases were included, 368 cases in the trial group were treated with TCM combined with Rivaroxaban, and 362 cases in the control group were treated with Rivaroxaban alone after surgery. Clinical efficiency was significantly higher in the test group [OR = 3.33, 95% CI (2.01, 5.53), P < .00001], the circumference of the affected limb was significantly lower in the thigh and calf, respectively [MD = -1.48, 95% CI (-1.88, -1.09), P < .00001], [MD = -0.54, 95% CI (-0.62, -0.46), P < .00001], pain scores were significantly lower [MD = -0.97, 95% CI (-1.58, -0.36), P = .002], coagulation index plasma fibrinogen (FIB) was significantly lower [MD = -0.85, 95% CI (-1.18, -0.52), P < .00001], coagulation function index D-2 aggregates were significantly reduced [MD = -0.69, 95% CI (-1.13, -0.24), P = .002], serum hypersensitive C-reactive protein (hs-CRP) measurements were significantly reduced [MD = -5.37, 95% CI (-9.20, -1.55), P = .006], complications measurement was significantly lower [OR = 0.60, 95% CI (0.27, 1.30), P = .20], activated partial thrombin time (ATPP) measurement was significantly lower [MD = 5.70, 95% CI (4.28, 7.12), P < .00001] and prothrombin time (PT) measurement was significantly lower [MD = 1.64, 95% CI (0.70, 2.57), P = .0006].ConclusionBased on the available evidence, TCM combined with Rivaroxaban for treating lower extremity DVT have better clinical efficacy and safety profile, reducing the risk of bleeding complications and adverse effects. Further improved studies are needed to support this inference.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
