Background and objectives: The aim of this retrospective study is to summarize our improvement of surgical procedures for radical resection of left hilar tumors involving the pulmonary trunk and determine its clinical feasibility.
Methods: From 2001 to 2008, four patients were selected for curative extended resection through multidisciplinary assessment and the pulmonary trunk was reconstructed via cardiopulmonary bypass (CPB). Surgical procedures were performed with posterolateral thoracotomy for two patients and anterolateral thoracotomy for the remaining two. CPB was performed via femoral artery-femoral vein cannulation on one patient and right atrial-aortic cannulation on the other three patients. Polytetrafluoroethylene patch or autologous pericardium was applied for reconstruction in different patients.
Results: The duration of the operations ranged from 300 to 440 min and with CPB lasting 35-106 min. Three patients developed non-specific complications with no mortalities and discharged within 12-17 days. One patient had no evidence of recurrence during 50 months follow-up. Three patients died of metastasis 5, 14, and 35 months after surgery.
Conclusions: CPB-supported extended resection of lung malignancies involving the pulmonary trunk is feasible. Left anterolateral thoracotomy through the fourth intercostal space with right atrial-aortic cannulation would be the convenient approach. Survival may be prolonged in some selected patients.
