Evers et al. Intraoperative Use of the Ventrain for Single Lung Ventilation After Iatrogenic Trauma to the Left Main Bronchus During Thoracoscopy: A Case Report. AA Case Rep 2017 Aug 15; 9 (4): 116-118

Ventilation during lung separation procedures
In a patient undergoing thoracoscopic esophagectomy and concomitant wedge resection, an iatrogenic lesion in the left main bronchus was observed following deflation of the right lung. Repair of the lesion required deflation of the brochial cuff. This challenging situation was resolved using Ventrain to oxygenate the patient through an Arndt Endobronchial Blocker through the lumen beyond the bronchial defect. With the use of this technique, oxygenation was maintained at an acceptable level during repair. Commented by H.P.
