Clamshell or sternotomy for double lung or heart-lung transplantation?
OBJECTIVE
To evaluate the influence of either incision on the lungs and chest wall.


METHODS
Ninety-two double lung (DLT) or heart-lung (HLT) transplantations were done since January 1990. There were 22 (24%) hospital deaths, leaving 70 patients with complete data for evaluation. We did 38 DLT and 32 HLT for end-stage chronic respiratory failure (n = 22) and primary (n = 34) or secondary (n = 14) pulmonary hypertension, using 37 fourth or fifth interspace clamshell incisions and 33 median sternotomies.


RESULTS
The clamshell group included a higher percentage of DLTs (73 vs. 33%, P = 0.001) but recipient age, gender, preoperative diagnosis, bronchial anastomotic complications, number of cytomegalovirus infection, episode of acute rejection per patient-months and incidence of bronchiolitis obliterans were not statistically different between the two groups. At a follow-up time of 3.7 +/- 2 years, the overall 5-year survival of 57% was not influenced by the type of incision. The clamshell incision caused sternal over-riding in 12 (32%) patients, and eight surgical clamshell revision were necessary as compared with one median sternotomy (P = 0.02). The clamshell incision was associated with a significantly higher incidence of postoperative chronic pain (27 vs. 6%, P = 0.02). Postoperative mechanical properties of the chest wall were significantly (P < 0.0001) worse in the clamshell-group patients while the intrinsic properties of the airways were not different.


CONCLUSIONS
The clamshell incision results in more postoperative deformity, chronic pain, and impaired function as compared with median sternotomy. A bilateral anterolateral thoracotomy without division of the sternum is proposed for the sequential bilateral lung transplantation technique.
