Shorter times should not be used, even if the colours look OK.) As penetration of the microsporidial spore is difficult, the dye content and the staining time are increased in the Modified Trichrome Blue Stain protocol. Intimal hyperplasia is seen between the 2 stents, and adherent fibrin is seen in the site of the second stent.
