A 76-­year-old ­female ­with chron­ic idiopath­ic throm­bo­cy­to­pen­ic pur­pu­ra ­required cor­o­nary ­bypass graft­ing. Preoperative treat­ment ­with ­high-­dose intra­ve­nous immu­no­glob­u­lin at a ­dose of 0.4 g/kg/day ­raised the plate­let ­count ­from 57,000 to 110,000/µL. After ter­mi­na­tion of car­di­o­pul­mo­nary ­bypass (CPB) the resid­u­al ­blood in the CPB cir­cuit was ­washed to ­reduce ­total immu­no­glob­u­lin G (IgG) lev­el, includ­ing plate­let-asso­ciat­ed immu­no­glob­u­lin G (PA-IgG), and ­returned to the ­patient. Intraoperative plate­let trans­fu­sion was ­used due to a ­drop in plate­let ­count to the pre­treat­ment lev­el. The post­op­er­a­tive lev­el of IgG and PA-IgG ­remained sig­nif­i­cant­ly low­er ­than pre­op­er­a­tive­ly. The post­op­er­a­tive ­course was unevent­ful and with­out bleed­ing com­pli­ca­tions. Perioperative man­age­ment of a ­patient ­with idiopath­ic throm­bocy­to­pen­ic pur­pu­ra under­go­ing ­open-­heart sur­gery is dis­cussed.
