[Comparative study of 4 types of polyester arterial prostheses].

The authors report a comparative study of 4 types of arterial prosthesis made of polyester. After implantation in the dog, the superiority of unfolded Rhodergon velvet prostheses was shown. They have excellent qualities for tissue reconstruction owing to presence of histological structures characteristic of large caliber arteries and absence of histological changes and hemorrhagic suffusion after the 12 th month following insertion.
