Objective: As the waiting period for lung transplant (LT) candidates with end-stage pulmonary emphysema (COPD) continues to increase, there is a need for alternative treatments to reduce the morbidity and mortality associated with COPD. We hypothesized that lung reduction (LR) may avoid the need for subsequent LT in patients on the waiting list that are also candidates for LR. Methods: From July 1994 to December 1995, 20 patients received LR as alternative to LT. The average age was 58±7 years; 11 were males. Eighteen patients had primary COPD and two had alpha-1 antitrypsin deficiency. Eighteen LRs were thoracoscopic (two bilateral and 16 unilateral) and two were done through a median sternotomy. Results: At a follow-up of 32±4 months, 19 patients are alive (19/20=95%). Fifteen patients (15/20=75%) are currently off the LT list and doing well: FEV1 is 40±18% predicted at 2 years compared with 22.7±6% before LR (P<0.001); FVC is 84±13% at 2 years compared with 55±7% (P<0.001) and the RV is 145±59% compared with 270±58% (P<0.001). One patient (5%) required extra-corporeal membrane oxygenation (ECMO) after LR to the contralateral side of the first procedure and subsequently died. Two patients (10%) are currently listed for LT because of persistent symptoms. One patient (5%) in whom deterioration was secondary to exposure to toxic fumes, underwent successful LT. One patient (5%) is doing well from the pulmonary standpoint but is being worked up for new severe coronary artery disease (CAD). The freedom from LT is 95% (19/20) and the freedom from repeat LR is 85% (17/20). Conclusions: LR has the potential to offer an effective palliative alternative to LT in 75% of selected patients up to 32 months of follow-up. Widespread use of bilateral LR is anticipated to further improve the results.
