Differential lung ventilation using Fogarty catheter after accidental damage of bronchial blocker cuff]

We performed differential lung ventilation using a Fogarty catheter after accidental damage of a bronchial blocker. A 57-year-old-man underwent thoracoscopic surgery for right pneumothorax. Anesthesia was induced with fentanyl and midazolam, and maintained with propofol and continuous epidural block with 2% mepivacaine. We used a single lumen endotrachial tube with a bronchial blocker for differential lung ventilation. We inserted the tip of the bronchial blocker into the right bronchus under fiberoptic broncoscopy after the patient had been placed in the lateral position. Four milliliters of air were injected into the bronchial blocker cuff before inserting the thoracoscope and differential lung ventilation was started. The right lung expanded suddenly because of accidental damage of the cuff one hour after starting surgery. We inserted a Fogarty catheter (10 Fr.) into the right bronchus under fiberoptic broncoscopy. Its balloon was inflated for differential lung ventilation. The procedure was performed successfully and uneventfully. We conclude that Fogarty catheter is an effective replacement for a damaged bronchial blocker cuff during differential lung ventilation.
