Abstract

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.

摘要

奇静脉造影术是术前检测食管恶性肿瘤不可切除性的一种有用技术。食管癌侵犯奇静脉是由于胸段食管与奇静脉在解剖位置上相邻。奇静脉造影术可通过经骨内注射肋骨或直接逆行导管插入术来进行。如果没有其他明显的胸内疾病，奇静脉完全阻塞表明食管癌不可切除。
