Resection via median sternotomy in patients with lung cancer invading the main pulmonary artery.
BACKGROUND
Conventional pneumonectomy via posterolateral thoracotomy is not always possible in cases with T4 tumour with widespread pulmonary artery invasion. Our objective is to present our surgical experiments in cases with a hilar mass who were thought to have pulmonary artery invasion, in whom we performed intrapericardial pneumonectomy through median sternotomy.


METHODS
Nine cases who had undergone intrapericardial pneumonectomy via median sternotomy were included in this study and evaluated retrospectively. These cases were thought to have right or left pulmonary artery invasion in preoperative evaluation.


RESULTS
Two cases had right and seven cases left pneumonectomy. Based on TNM classification, two patients were Stage IIB, two Stage IIIA and five Stage IIIB in postoperative histopathological examination. Either right or left main pulmonary artery invasion was seen in IIIB cases while invasion was limited to the pericardium in the others. Lymph node involvement was detected in seven cases while six cases were N1, and one case was N2. There was no operative mortality.


CONCLUSIONS
Standard posterolateral thoracotomy might not be possible in all cases, particularly in patients with hilar tumours invading the main pulmonary artery. In such patients an intrapericardial approach with median sternotomy provides an easier and safer alternative while making it possible to have wider lymph node dissection. Furthermore, if necessary, hemi-clamshell incision can easily be added to this approach.
