[Preoperative aspirin therapy--a contraindication for kidney transplantation?].

INTRODUCTION

The influence of ASA treatment on haemostasis is still debated. There are doubts in case of emergency operations, especially in transplant patients, concerning dosage and change of medication.

METHODS

Our results are based on an analysis of the therapeutical behavior in German transplantation centers. The question of transplant suitability, dosage and haemostatic effects will be discussed in comparison to the literature.

RESULTS

85.7% of the transplantation centers perform the operation despite of and under ASA treatment. In these cases an increased bleeding tendency is tolerated and observed in 33.3% of the centers. An increased mortality has not been reported. Most of the transplantation centers accept a dosage of 100 mg ASA daily. Only 14.3% of the transplantation centers refuse the operation in ASA treated patients.

CONCLUSIONS

Correctly indicated ASA treatment (cardiac arrhythmia, patients with embolism or thrombosis) isn't a contraindication for renal transplantation (daily dosage up to 100 mg). In elective cases however, a preoperative change of the medication is recommended, e.g. the use of heparin instead of ASA.
