Wall reinforcement with highly porous Dacron mesh in aortic surgery.

Wall reinforcement with highly porous synthetic Dacron mesh was devised and evaluated in various aortic operations. Excellent attachment of the mesh to the aortic wall, good preservation of pliability of the aorta, and efficient pressure resistance with minimal scar tissue formation were the usual findings. This type fo wall reinforcement was employed in 60 patients for the following indications: 1) prevention of suture line complications; 2) wall reinforcement of aortic aneurysm without resection; 3) reinforcement of adventitia or autogenous vein following thromboendarterectomy. It is concluded that reinforcement with highly porous synthetic Dacron mesh should be superior to reinforcement with conventional prosthetic Dacron graft.
