In this experiment, Dacron felt was wrapped onto the site of the prosthetic vascular grafting of the canine aorta. Gross inspetion, histological examination and microangiography were performed at various intervals during the period one week to one year after grafting. Tensinometry was performed two months after grafting to compare the tension of the cases on which Dacron felt wrapping were performed and not performed. The following results were obtained.
1) Forty days after grafting, the Dacron felt was healed closely with both aortic wall and the vascular graft by connective tissue ; microangiogram also showed good neovasculariization in the Dacron felt.
2) Two months after grafting, the Dacron felt was sufficient to reinforce the anastomotic site and it was stronger than the case on which Dacron felt was not performed.
3) Neither thinning nor necrosis of the arteiral wall under the Dacron felt was noted.
4) The natural course of the formation of the pseudointima of the vascular graft was not influenced by the Dacron felt.
From the results mentioned above, it seems that the Dacron felt wrapping is a safe and effective method to reinforce the prosthetic vascular anastomosis.
