Lung isolation in patients with previous lung resections: Selective sequential lobar blockade using a Fuji Uniblocker® endobronchial blocker

Airway Management of the Right Anterior Segmentectomy through Uniportal video-assisted thoracoscopic surgery (VATS) after left pneumonectomy by an adapted double-lumen endobronchial tube (DLT): a case report

Background

Lung resection after previous contralateral pneumonectomy is rare. We present a case of right anterior segmentectomy despite previous left pneumonectomy, demanding special airway management strategy.

Case presentation

A 48-year-old woman who had left pneumonectomy 2 years ago was scheduled to have the right anterior segmentectomy through uniportal video-assisted thoracoscopy (VATS). A 32-French (Fr) left-sided double-lumen endobronchial tube (DLT) was chosen and adapted. The DLT was intubated into the bronchus intermedius. And the upper lobe can be isolated from the ventilation in the middle and lower lobes when the bronchial cuff’s inflated. The perioperative period was uneventful and the pathological diagnosis was adenocarcinoma.

Conclusion

Lung cancer radical resection was discouraged after previous contralateral pneumonectomy partly due to the challenging ventilation and isolation. With this new DLT adapting and intubation technique showed in this case, the challenging ventilation and isolation that deter the implementation of the operation mentioned above could be solved.

Single-lung ventilation with bronchofibroscopy during lung resection surgery

Lung isolation using one-lung ventilation is common during thoracic surgery procedures, as it allows proper visualisation and manipulation of the lung to be operated on. Selective lobar blockade has been described in patients that do not tolerate one-lung ventilation, and is usually achieved using endobronchial blockers. However, it depends on endobronchial blocker availability, its complexity regarding proper positioning, and the need for constant monitoring to ensure the correct placement of the bronchial seal. In the clinical case to be described, a new method was used to increase the available surface for oxygen exchange. This was accomplished by means of direct supply of oxygen through the bronchoscope's working channel to one of the not-to-be operated-on, non-ventilated lung lobes. With this technique, the surgeon had an optimal operating field, oxygenation from one-lung ventilation improved and no perioperative complications were found.
