It is done to evaluate and treat pulmonary problems when noninvasive procedures are nondiagnostic or unlikely to be definitive.
The principal indications for thoracotomy are
Both lobectomy and pneumonectomy are done most commonly to treat lung cancer.
Video-assisted thoracoscopic surgery has largely replaced thoracotomy for open pleural and lung biopsies.
Three basic approaches are used:
Limited anterior or lateral thoracotomy: A 6- to 8-cm intercostal incision is made to approach the anterior structures.
Posterolateral thoracotomy: The posterolateral approach gives access to pleurae, hilum, mediastinum, and the entire lung.
Sternal splitting incision (median sternotomy): When access to both lungs is desired, as in lung volume reduction surgery, a sternal splitting incision is used.
Patients undergoing limited thoracotomy require a chest tube for 1 to 2 days and in many cases can leave the hospital in 3 to 4 days.
Complications are greater than those for any other pulmonary biopsy procedure because of the risks of general anesthesia, surgical trauma, and a longer hospital stay with more postoperative discomfort. The greatest hazards are
Mortality for exploratory thoracotomy ranges from 0.5 to 1.8%.
