Abstract
Objective To evaluate the safety,biocompatibility and effectiveness of the new absorbable occluder.Methods A total of 27 adult Beagle dogs were enrolled and divided into 2 groups.Ventricular septal defect (VSD)animal models were prepared in experimental group (17 dogs) by open chest.VSD was punctured and the new absorbable occluder was implanted by guiding of transthoracic echocardiography.Laboratory examinations were done after surgery and pathological samples were obtained after euthanasia in the 3rd,6th,9th and 12th month.Then the safety and effectiveness were evaluated by comparing laboratory results,clinical and histopathological manifestations of the 2 groups.Results All dogs survived.No complications occurred.Histopathological examination showed the occluders were biocompatible and immunohistochemical examination showed epithelial cells and new vessels were growing on the occluder surface.Conclusions The new absorbable occluder has been proven to be safe,effective and biocompatible in this study.关键词
