Abstract:
Endoluminal brachytherapy for lung cancer ensures the delivery of a maximal therapeutic radiation dose to the tumor with a minimal effect on normal surrounding tissues. We report on a 62-year-old man, who acutely developed LBBB and heart failure 48 hours after the second course of combined endoluminal and external beam radiation therapy. After administration of angiotensin converting enzyme inhibitors, diuretics, and anti-inflammatory drugs, electrocardiographic changes resolved and patient completely recovered. Radiotherapy was reintroduced after ten days.
