Probable allergic reaction to cyclosporin and early formation of thrombi on a pulmonary artery catheter: two unusual complications during bilateral lung transplantation.

We describe a patient who had two rare complications (a probable allergic reaction to cyclosporin and the early formation of a right atrial thrombus) during bilateral sequential single lung transplantation performed under the one anaesthetic. The thrombus, discovered at the end of the procedure, was then removed under cardiopulmonary bypass. Peroperative transoesophageal echocardiography was useful in providing critical diagnostic and therapeutic information.
