The aim was to evaluate the anatomical success rate (complete closure of the treated vein within 6 months after the intervention) as the primary endpoint and health-related quality of life (HRQoL), venous clinical severity score (VCSS), pain score and adverse events as secondary endpoints.
Methods included a systematic review of journals between January 1996 and September 2018, in which randomized controlled trials (RCTs) were selected.
The risk of bias and quality of publications were assessed.
A total of 20 RCTs with 4570 patients were analyzed.
Data were extracted and analyzed using mixed treatment comparisons in a network meta-analysis.
The results showed that the VenaSeal system had the highest probability of being rated best on the primary outcome measure (anatomical success).
It also performed well for secondary endpoints, particularly in the reduction of postoperative pain and the occurrence of adverse events.
The likelihood of adverse events was highest in the sclerotherapy group.
The conclusion of this study is that the VenaSeal system is a promising therapeutic option for anatomical success after 6 months in CVI patients and causes fewer adverse events (such as wound and groin infections and pulmonary embolism) compared to other interventions in the study.
However, additional economic analyses, including cost-benefit analyses, are recommended to provide further insight for patients, payers and providers.
