Contralateral tension pneumothorax during video-assisted thoracic surgery for lung cancer in a patient with obesity and rib fractures: a case report and review of the literature.

We present the clinical course and discuss the mechanism of development of this potentially life-threatening complication in the present case with a review of the literature.
