BACKGROUND Evidence comparing fibrin sealants (FSs) in surgery are limited. This study evaluated the efficacy and safety of FSs, and manual compression in peripheral vascular surgery. METHODS A systematic review of randomized trials was conducted in Medline, Embase, and Cochrane databases within the last 15 years. Data were available to conduct a network meta-analysis (NMA) in peripheral vascular surgery. Fibrin
sealant treatment arms were further broken-down and assessed by clotting time (i.e., 2-min [2C] or 1-min [1C]). The primary efficacy outcome was the proportion of patients achieving hemostasis by 4 min (T4). Treatment-related serious and non-serious adverse events (AEs) were qualitatively assessed. RESULTS Five studies (n = 693), were included in the NMA. Results predicted VISTASEAL 2C, followed by EVICEL 1C, had the highest probability of achieving T4. Compared with manual compression, significant improvements in T4 were found with VISTASEAL 2C (relative risk [RR] = 2.67, 95% CrI: 2.13-3.34), EVICEL 1C (RR = 2.58, 95% CrI: 2.04-3.23), VISTASEAL 1C (RR = 2.00, 95% CrI: 1.45-2.65), and TISSEEL 2C (RR = 1.99, 95% CrI: 1.48-2.60). TISSEEL 1C was not significantly different than manual compression (RR = 1.40, 95% CrI: 0.70-2.33). Among FSs, VISTASEAL 2C was associated with a significant improvements in T4 compared with VISTASEAL 1C (RR = 1.33, 95% CrI: 1.02-1.82), TISSEEL 2C (RR = 1.34, 95% CrI: 1.05-1.77), and TISSEEL 1C (RR = 1.90, 95% CrI: 1.18-3.74). Treatment-related serious and non-serious AE rates were typically lower than 2%. CONCLUSIONS In peripheral vascular surgeries, VISTASEAL 2C and EVICEL 1C were shown to have the highest probabilities for achieving rapid hemostasis among the treatments compared. Future studies should expand networks across surgery types as data become available.
