Emergency resection of a carinal adenoma

Emergency carinal resection is a daunting and infrequently performed procedure.


A man aged 46 developed acute stridor and fibreoptic bronchoscopy showed a large pedunculated mass at the carina. The right main bronchus was completely obstructed and the left main bronchus about 50% obstructed. Biopsies were non-diagnostic. CT showed the mass to occupy the distal tracheal lumen and there was a large posterior extrabronchial component (Figure 1). The posterior tracheal wall bisected the tumour mass. Endobronchial resection, attempted via a rigid bronchoscope, caused moderate bleeding into the distal airways and the procedure was terminated. Over the next two days ventilation became increasingly difficult, high inflation pressures being required to achieve satisfactory tidal volumes and adequate oxygenation. A decision was made to attempt carinal resection through a right thoracotomy; on left lateral positioning, however, he could not be ventilated satisfactorily and inflation pressures and pCO2 rose. Therefore cardiopulmonary bypass was established by femoro-atrial cannulation. After median sternotomy the superior mediastinal structures were dissected out and the anterior pericardium was mobilized as a pedicle with a broad base of attachment to the aortic arch. The trachea was incised just above the carina to expose the endotracheal tumour (Figure 2). The posterior component arising from the posterior tracheal wall and the adjacent main bronchi was excised with a circumferential margin of normal tracheal wall. The pericardial flap was rotated to bring its serosal surface into the tracheal lumen, and was sutured to the margins of the resulting defect in the posterior wall of the trachea and principal bronchi. Completion bronchoscopy showed widely patent distal trachea and principal bronchi. Mechanical ventilation had to be continued for seven days because of non-cardiogenic pulmonary oedema. Three weeks postoperatively he underwent bronchoscopy and dilatation of a mild anastomotic stricture.

After another four weeks he was discharged home. The final pathological diagnosis was pleomorphic adenoma with apparently complete resection. Over the ensuing four months he required three further tracheal dilatations, which were increasingly difficult. He then underwent permanent stenting of the left main bronchus and distal trachea with two Gianturco non-covered wire stents. 2 years later he had no stridor and was symptom-free.


The most common cause of tracheal or carinal obstruction is lung cancer. When there are signs of respiratory failure, the priorities are to restore adequate ventilation and obtain a pathological diagnosis.1

The choice of bronchoscopic techniques includes Nd-YAG laser, diathermy and cryotherapy,2 all of which carry a risk of bleeding. Thereafter, complete resection with primary reconstruction of the airways offers the best chance of cure. Anaesthesia presents special difficulties in these cases. High-frequency jet ventilation can be a useful adjunct. In our patient the ventilatory difficulties were unsurmountable and cardiopulmonary bypass was necessary.

The stricture that developed postoperatively, caused by fibrosis of the pericardial patch, is a well documented complication. Laser and balloon dilatation offer immediate relief, but in cases of recurrence an endobronchial stent can provide good function in the long term.

In the UK, most tracheal and carinal surgery is undertaken in a few specialized centres and, even in these, the large majority of resectional procedures are done electively, in a controlled environment. However, any cardiothoracic centre may find itself confronted with one of these emergencies; and if transfer is too dangerous to the patient, the local surgeons may have to rely on basic principles and their trade craft. In the instance described here, they were much helped by the availability of cardiopulmonary bypass.
