Azygography in the pre-treatment evaluation of oesophageal carcinoma.

Azygography is a useful technique for the pre-operative detection of unresectability of oesophageal malignancies. Invarison of the azygos vein by oesophageal carcinoma occurs because of the anatomic proximity of the thoracic oesophagus and the azygos vein. Azygography may be performed by either intraosseous injection of a rib or by direct retrograde catheterization. Complete obstruction of the azygos vein indicates that an oesophageal carcinoma is unresectable if no other intrathoracic disease is evident.

Transcatheter arterial embolization in the management of bleeding in the cancer patient.

Selective transcatheter arterial embolization was performed in 7 cancer patients with gastrointestinal or uterine bleeding. Most were bleeding from neoplastic tissue and were refractory to conservative management. Complete and permanent cessation of bleeding was obtained in 5 patients, including 3 with gastric bleeding, 1 with colonic bleeding, and in 1 with uterine bleeding. Successful arterial embolization allowed further treatment of the underlying disease which was particularly critical as these patients were poor surgical candidates. No significant or prolonged side effects were noted.
