Which fibrin sealant can be stored frozen, refrigerated, or at room temperature?

• A. Tisseel
• B. D-Stat Flowable
• C. Surgiflo
• D. Vistaseal

Answer: (D)

Fibrin sealants have specific storage guidelines, and the one that allows you to store it in any of the three conditions—frozen, refrigerated, or at room temperature—offers the most flexible handling in different clinical settings. Vistaseal is labeled to be stable across these temperature ranges, so it can be kept frozen for long-term storage, kept cold for short-term use, or left at room temperature when rapid availability is needed. This broad stability contrasts with the other products, which require more restrictive storage (typically refrigeration and limited or no allowance for freezing or room-temperature storage). That flexibility in Vistaseal makes it the best fit for the described storage options.
