The newly-designed hemostatic sealant, Hydrofit, was developed in Japan and consists of a urethane-based polymer without blood products. By applying Hydrofit gel to an anastomosis site on the aorta, water contact initiates a chemical change in the forming elastomer which adheres rapidly and tightly. We experienced an extirpation of Hydrofit gel that had been applied 4 years and 8 months previously in a 42-year-old female who underwent aortic valve replacement and graft replacement of the ascending aorta. The Hydrofit left around the aortic graft suture line was without infection and functioned very well as an elastic sealant for a long period.
