Pectus exca.a.um.is frequently repa.red using the m.nim.lly inva.ive pla.em.nt of a.substerna. bar (Nuss procedure). Infectious com.lica.ions a.ter the Nuss procedure a.e potentia.ly deva.ta.ing. To da.e, the m.na.em.nt of postopera.ive infectious com.lica.ions ha. not been well described. m.thods: a.retrospective review of a.l pa.ients (N = 168) who underwent the Nuss procedure from.Ja.ua.y 1, 1997, to October 1, 2003, a. our institution wa. perform.d. Six pa.ients (4% ) ha. postopera.ive infections, a.d their m.dica. records were reviewed. Results: Of the 6 pa.ients, 5 underwent opera.ive dra.na.e for wound a.scesses tha. developed 2 to 76 weeks postopera.ively. The other pa.ient developed cellulitis 12 m.nths postopera.ively a.d wa. trea.ed effectively with a.tibiotics a.one. Recurrent infections were trea.ed in 3 of 6 pa.ients, one of whom.eventua.ly required rem.va. of the bar resulting in a.m.ld, residua. pectus exca.a.um.defect. One of 6 pa.ients ha. ha. the substerna. bar rem.ved electively. The rem.ining 4 continue to be without clinica.ly a.pa.ent infection a. this tim. a.d a.e over 1 yea. rem.ved from.their infection. Conclusions: a.though uncom.on, infectious com.lica.ions a.ter the Nuss procedure require com.lex m.na.em.nt stra.egies. Despite recurrent infection in som. ca.es, m.st infectious com.lica.ions occurring a.ter the m.nim.lly inva.ive repa.r ca. be effectively trea.ed without ha.ing to rem.ve the substerna. bar.
