Does azygography improve the preoperative detection of mediastinal spread in patients with lung cancer?
Azygography is proposed as a radiographic method to detect mediastinal spread of lung cancer preoperatively, potentially aiding in determining surgical operability.

Azygography may aid preoperative mediastinal staging in lung cancer; leaves open its clinical utility pending validation studies.
THE preoperative determination of inoperability of carcinoma of the lung remains a difficult problem. In spite of a variety of preoperative investigations the tumors of a third of the patients surgically explored are beyond the limits for resection.1 Although the value of palliative resection is not denied many cases are too far advanced to benefit from any form of surgery. Others may be better treated with combined therapy if the extent of the disease is known before operation.2 Radiographic visualization of the azygos vein, azygography, provides another means of detecting mediastinal spread of neoplastic disease before operation.3 , 4 After several reports . . .
