ESTUDO COMPARATIVO DAS ANASTOMOSES ARTERIAIS COM FIO ABSORVÍVEL E NÃO ABSORVÍVEL EM SUÍNOS EM CRESCIMENTOAbstract
The aim of this study is to observe polypropylene and polyglactine 910 anastomosis, in growing pigs after twelve months. Sixteen female "Landrace" piglets were distributed into two groups : A and B. After being weighed, the animals underwent aorta abdominalis transversal section under arteria renalis dextra and sinistra, diameter measurement, and anastomosis in continuous suture with the above mentioned threads. One year later, the animals were euthanized and new measurement was performed. In both groups, it was noticed that heavier weights are related to bigger arterial diameters. An average body weight increase of 1027,5 % on group A and 1242,9 % on group B was observed. For statistics, use of WILCOXON and MANN-WHITNEY tests was made. Torn or intact polypropylene threads remained on arteries, protruding into the lumen. On group B, complete absorption occurred. It was concluded that polypropylene and polyglactine 910 threads allow arterial growing around end-to-end anastomosis area , on aorta abdominalis, in pigs.
