Description
An experimental study of the Dacron felt wrapping to reinforce the prosthetic vascular anastomosis was done on the infrarenal aorta of the dog. Gross inspection, histological examination and microangiography were performed at various intetvals after the operation. Tensile strength was examined two months after grafting.
Histological examination revealed that the Dacron felt remained fixed to the both aortic wall and the prosthetic vascular graft even 40 days after the operation. Microangiogram also showed good neovascular infiltration in the Dacron felt. Tensinometry revealed that the strength of the wrapping group was stronger than that of the non-wrapped group. Thus, Dacron felt wrapping is considered to be a safe and effective method of reinforcing the prosthetic vascular anastomosis.
