Marlex mesh has been used as a prosthesis in seven patients for the repair of thoracic wall or pericardium defects resulting from surgery. Mediastinal shift and paradoxical movement of the chest wall after operation was minimal. The post operative course was generally good. But in one case of pneumonectomy for lung cancer developed empyema after five months of operation which was thought due to marlex mesh remaining in the thoracic dead space. Also in the other case of pneumonectomy marlex mesh was not adhesive to the chest wall.
