Combined angiography and mediastinoscopy in bronchogenic carcinoma.

Abstract Pulmonary angiography was utilized prior to surgery in an attempt to define involvement of central portions of pulmonary arteries, veins, pericardium, and superior vena cava in lung cancer patients. Mediastinoscopy was performed under general anesthesia just prior to bronchoscopy. These procedures allow not only visible inspection of endobronchial disease and peribronchial extension, but also biopsy and histological assessment prior to thoracotomy. The combined findings at angiography and thoracotomy are correlated in 241 cases. Correlation of findings in 199 who underwent both procedures indicates that in the authors' experience this combined approach provides the best current evaluation prior to thoracotomy.
