Polyvinyl formalinized (Ivalon) sponge has been tested as prosthetic material by several groups, with some variation in findings.1,6,7,9 It has unique and desirable characteristics, which include (1) inherent ability to hold a shape which adds greatly to the ease of placement and decreases the likelihood of wrinkles; (2) ease in fashioning into any desired shape by heating while molded; (3) a high degree of porosity which allows rapid and secure fibroblastic penetration—conversely, the degree of porosity can be controlled at will by varying the compression used during molding; (4) ability to fuse itself together, without seams. In experimental and clinical use as an arterial replacement it has seemed to have approximately the same tendency to thrombosis as other materials; however, it has had the serious disadvantage of low inherent strength, and the incidence of aneurysm formation and rupture has been rather high, especially when it is used in the
