Úlcera de córnea por Serratia marcescens após ceratoplastia penetrante

Sorratia marcescens keratitis after penetrating keratoplasty

RESUMO

Relataram-se dois casos de úlcera corneana por Serratia marcescens após transplante de córnea. Os dois pacientes receberam córneas de um mesmo doador, conservadas por 24 horas em meio Dexsol e foram operados em hospitais diferentes, por diferentes cirurgiões.

Os dois pacientes foram retransplantados. Um deles apresentou recidiva da úlcera de córnea por Serratia, e foi submetido a recobrimento conjuntival. O outro paciente evoluiu com opacificação e vascularização do segundo enxerto.

Discute-se o mau prognóstico nos casos de úlcera de córnea por Serratia marcescens e a possibilidade da córnea doadora ser a fonte de infecção em transplantes de córnea.

Palavras-chave:
Infecção após transplante de córnea; córnea doadora; meio de conservação; Serratia marcescens

SUMMARY

Two cases of Serratia marcescens keratitis after corneal transplantation are related. The two patients received cornea from the same donor, preserved in Dexsol medium for 24 hours and had been operated in different hospitals by different surgeons.

A repeat corneal transplantation was performed in both patients. Recurrent Serratia keratitis occured in one of the cases and a conjunctival flap was performed. The other patient developed total opacity and vascularization of the second graft.

The bad prognosis in cases of Serratia marcescens keratitis and the possibility of donor cornea as source of infection are discussed.
