OBJECTIVE: To investigate the outcomes of treatment strategies for proximal and iliofemoral deep vein thrombosis (DVT).
METHODS: Randomised controlled trials (RCTs) investigating outcomes of catheter directed thrombolysis (CDT), ultrasound assisted CDT (USCDT), percutaneous aspiration thrombectomy (PAT), and best medical therapy (BMT) for proximal DVT from 2000 onwards were considered. MEDLINE, EMBASE, and CINAHL were searched using the Healthcare Databases Advanced Search interface developed by the National Institute for Health and Care Excellence. The primary outcome was the rate of post-thrombotic syndrome (PTS), which was defined using the Villalta scoring system (score of ≥5). Secondary outcomes included vessel patency, recurrence, bleeding, and mortality. The network of evidence was summarised using network plots, and random effects network meta-analyses were performed. The certainty of evidence was assessed using the Certainty In Network Meta-Analysis (CINeMA) approach.
RESULTS: Seven RCTs meeting the inclusion criteria were identified. There were direct comparisons between medical therapy, CDT, and USCDT across outcomes, except for patency. There were no direct comparisons between medical therapy and PAT (except for patency), and USCDT and PAT. There was no significant difference observed in PTS between the treatment modalities for proximal and iliofemoral DVT (low certainty). There was a significant difference in patency rates between medical therapy and USCDT (odds ratio [OR] 9.46, 95% confidence interval [CI] 3.05 - 29.35; low certainty) and CDT (OR 2.03, 95% CI 1.46 - 2.80; low certainty) in favour of USCDT and CDT, respectively, for proximal DVT. USCDT significantly improved patency rates compared with CDT (OR 4.67, 95% CI 1.58 - 13.81; very low certainty) for proximal DVT. There was no significant difference in DVT recurrence, bleeding, or mortality between treatment groups for proximal and iliofemoral DVT (low to moderate certainty for most comparisons).
CONCLUSION: USCDT may improve patency rates compared with BMT and the other interventional treatment modalities used for the management of proximal DVT. However, no treatment modality showed superiority with regard to a reduction in PTS, and overall, the quality of available evidence is poor.
