The influence of preoperative abciximab treatment on perioperative risks was analyzed. Six groups were formed in consecutive patients (n = 957, 1/1994-3/2000) operated upon for CABG according to the urgency of the intervention and the type of preoperative haemostaseological treatment. Thirty-one patients underwent urgent/emergency CABG with preceding abciximab treatment. After pretreatment with abciximab the surgical results did not differ from patients with other types of preoperative haemostaseological treatment. CABG can be performed with similar results in abciximab pretreated patients as in patients with other types of preoperative haemostaseological treatment.
