title: Coronary artery bypass grafting (CABG) in patients with immune thrombocytopenia (ITP): a community hospital experience and review of the literature.
abstract: We reviewed the records of 51 patients with Immune Thrombocytopenia (ITP) who underwent Coronary Artery Bypass Grafting (CABG) at Charleston Area Medical Center between June 1992 and September 2005. There were 41 males and 10 females with a median age of 68 years (range 49-87). Four patients had a previous splenectomy, one of whom had it performed concomitantly with the CABG. Three patients were on chronic corticosteroids on admission. The median pump time was 114 minutes (range: 42-244 minutes). The median cross-clamp time was 62 minutes (range 22-192 minutes). The median total chest tube drainage postoperatively was 1,346 cc (range: 265-9875cc). The mean preoperative and 24 hour postoperative platelet count was 126,000 (range 58,000-323,000) and 99,000/mm3 (range: 27,000-194,000), respectively. Twenty-one (40%) patients received platelet transfusions. Platelets were given intraoperatively or postoperatively in all but two of those patients. The median number of units of platelets given was 10 (range: 6-52). Twenty-seven (53%) received packed red cells intraoperatively or postoperatively. The median number of red cells given was 2 (range: 1-34). Other hemostatic agents given intraoperatively/ postoperatively included aprotinin (8 patients), aminocaproic acid (10 patients), DDAVP (5 patients), and intravenous gammaglobulin (IgG) in 3 patients. Thirteen patients were given corticosteroids preoperatively with little improvement in platelet count. CABG may be successfully performed in ITP patients with moderate thrombocytopenia (> or = 50,000/mm3) using conventional therapies (e.g., transfusions, IV IgG, hematinics) without the need for preoperative splenectomy or prolongation of hospital stay. However, a prospective study on the ideal management of ITP patients undergoing CABG would be beneficial.
