[Transient complete atrioventricular block during renal transplantation].

A 25-year-old female underwent renal transplantation. The patient had no complication preoperatively except hypertension. Preoperative electrocardiogram revealed no abnormality. Anesthesia was maintained with sevoflurane. Donor kidney was perfused with University of Wisconsin (UW)'s solution (4 degrees C) after removal. Transient complete atrioventricular block appeared twice after reperfusion of the transplanted kidney. Adenosine in the UW's solution was considered the major cause of atrioventricular block in this patient. Attention must be paid to the occurrence of atrioventricular block and bradycardia shortly after reperfusion in the case where UW's solution was used for donor kidney perfusion.
