[Lung transplantation in Hanover: an interim balance-sheet after ten years].

BACKGROUND

We reviewed our experience with various forms of lung transplantation (heart-lung [HLTx], bilateral lung [BLTx] and single lung [SLTx]) from December 1987 to September 1998 at Hannover University.

PATIENTS

In 258 patients 282 procedures (46 HLTx, 142 BLTx and 94 SLTx) were performed. Major indications were pulmonary fibrosis (n = 73), obstructive lung disease (n = 55), cystic fibrosis (n = 48), primary pulmonary hypertension (PPHT, n = 36), secondary pulmonary hypertension (n = 30) and retransplantation (n = 24).

RESULTS

The 1-, 3- and 5-year survival rates in all 258 recipients were 77%, 70% and 63% respectively. Significantly better 1-year survival was noted in patients with cystic fibrosis (90%), pulmonary fibrosis (81%), obstructive lung disease (71%) and secondary pulmonary hypertension (83%) when compared to patients with primary pulmonary hypertension (58%). There was no significant difference in actuarial 1-year survival rates between the different procedures (HLTx 78%, BLTx 77%, SLTx 77%). Bronchiolitis obliterans syndrome (BOS) proved to be the major obstacle for long term survival. Actuarial freedom from BOS was 80% at 1 year and only 45% at 5 years. Various treatment strategies including augmentation of immunosuppression could only temporarily halt the deterioration of lung function in the majority of patients with BOS.

CONCLUSIONS

Lung transplantation provides a true therapeutic option for patients with endstage lung disease. However, improved long term outlook will depend on a better understanding and treatment of bronchiolitis obliterans.
