RESUMO

Twelve mongrel dogs were used in this study to create abdominal aortic aneurysm (AAA) with endoleak after endovascular treatment. The next step was seal this endoleak with an embolic material called Onyx(R) The presence or occlusion of the endoleaks was proved by computer tomography and angiography. Succeed in the creation of the experimental model was observed in 9/12 dogs. OnyxÒ was capable to seal endoleaks in all nine dogs that survived from AAA creation. The occlusion was stable until the end of the study and the histological analysis showed minimal inflammatory response to Onyx(R).
