Use of a Dacron mesh coated pericardium for aortic augmentation

A technique is described for aortic augmentation with Dacron mesh coated pericardial patch. This method avoids the use of synthetic graft material with the potential for weak adherence of pseudointima and microembolization. Hemostasis is improved and fibrous tissue ingrowth into the mesh prevents late aneurysm formation. The incorporation of the pericardial patch into the aortic wall and the normal endothelialization of the patch is documented after a 5-year follow-up.
