Usefulness of Bronchography with Non-turbid Contrast Agent in Stent Therapy for Malignant Bronchial Obstruction

Abstract

A 71-year-old man presented with cough, sputum and general malaise 6 months after operation for esophageal cancer. Bronchofiberscopy demonstrated obstruction of the left main bronchus due to recurrent esophageal cancer. Bronchography using a non-turbid contrast agent (Iotrolan 300) accurately demonstrated the location and dimension of the bronchial tumor, and did not cause any adverse reaction. Bronchography using Iotrolan 300 when inserting stent may be useful in the treatment of bronchial stenosis, because it dose not obscure bronchoscopic vision and demonstrates the bronchial tumor clearly.
