ABSTRACT
ABSTRACT Objective:
The aim of this study is to compare micro-sutures commonly used in our midst.Methods:
In this double-blind study, 30 Wistar rats were operated randomly divided into three groups matched according to the suture used (Nylon 10-0, 75micron, brands Microsuture(r), Polysuture(r) and Ethicon(r)). We analyzed the number of surgical nodes required, bleeding, surgical time and histological evaluation.Results:
There was no significant difference between the amount of stitches of arterial suture per anastomosis. Surgical time was longer in Microsuture(r) group as compared to Polysuture(r) (p ≤ 0.05). Bleeding in Microsuture(r) group was higher when compared to the others (p <0.01). In the histological analysis, the Microsuture(r) group showed a greater tendency to develop fibrosis and aneurysm in surgical site than the others (p <0.01 and p≤0,05, respectively). Similarly, the Ethicon(r) group showed less tendency to myointimal proliferation than the rest. (p = 0.025).Conclusion:
The results confirm the relevance of the choice of surgical thread as an independent determining factor for the success of the procedure, besides serving as a rational subsidy for a better cost-benefit analysis. Level of Evidence I, Experimental Study, Controlled Animal Study.
