21/26. Tracheoplasty--a new operation for complete congenital tracheal stenosis.

    This is a report of a case of complete congenital tracheal stenosis confirmed by tracheobronchogram. The stenosis also involved the origin of the right main bronchus. The membranous portion of the trachea was absent. It was repaired through a sternotomy and right thoracotomy aided by partial cardiopulmonary bypass. The posterior trachea was opened from larynx to carina and on into the right main bronchus, and each posterior tracheal edge was sewn to the anterior wall of the esophagus with a running Prolene suture. Three months after repair bronchoscopy showed that the new membranous trachea was epithelialized and the entire airway was of good caliber; the only problem was a diffuse tracheomalacia. He died in his seventh postoperative month after a major airway complication due to tracheotomy, which occurred after an elective bronchoscopy. It is obvious that this operation is technically feasible. It was hoped that his airway would become sufficiently stable to allow the tracheotomy tube to be removed at some time in the future.

22/26. Post-traumatic bronchial stenosis and acute respiratory insufficiency.

    A 31-year-old woman sustained multiple injuries, including severe contusion of the right lung with massive subcutaneous emphysema. Four weeks later she was transferred to our institution with post-traumatic adult respiratory distress syndrome and carbon dioxide retention, resulting from a postlaceration stenosis of the left main-stem bronchus. Bronchoplasty was contraindicated because of the serious condition of the patient. Repeated bronchial dilatations produced initial improvement in oxygenation and minute ventilation requirements. However, because of the nature of the stenosis and the lack of recovery of right lung function, the patient's encouraging clinical course reached a plateau and attempts at weaning from the respirator were unsuccessful. Bronchoplasty was performed on postadmission day 50 and resulted in gradual recovery of pulmonary function. Six months following discharge, the patient continues a steady improvement. Management of the patient's injuries represented a unique challenge previously unencountered.

23/26. Failure of the laryngeal mask airway (LMA) to ventilate patients with severe tracheal stenosis.

    The Laryngeal Mask Airway (LMA) was used during the resuscitation process in two patients with severe tracheal stenosis. In both cases the LMA failed to restore ventilation and both succumbed as a result of hypoxemic cardiac arrest.

24/26. Tracheal approach to pulmonary artery sling associated with funnel-shaped tracheal stenosis.

    pulmonary artery sling with concomitant funnel-shaped tracheal stenosis is a rare but potentially lethal congenital condition. Conventional surgical division and reanastomosis of the aberrant left pulmonary artery to the main pulmonary artery carries a high risk of postoperative ventilatory difficulty from an uncorrected tracheal stenosis. A primary tracheal approach via a right thoracotomy without pulmonary bypass is described.

25/26. Respiratory failure due to tracheobronchomalacia.

    A case is described of tracheobronchomegaly progressing to extensive tracheomalacia, complicated by episodic choking, recurrent pulmonary infections, and irreversible hypercapnic respiratory failure. A Y-shaped tracheobronchial stent was placed endoscopically to splint the trachea open, with excellent clinical and physiological improvement. New stent designs may provide long term palliation in selected cases of diffuse tracheal collapse or stenosis, and offer an alternative to surgical repair.

26/26. Successful weaning from mechanical ventilation following balloon mitral commissurotomy.

    Successful weaning from mechanical ventilation (MV) following percutaneous balloon mitral commissurotomy (BMC) is reported in a 59-year-old woman with severe symptomatic rheumatic mitral stenosis. The patient was admitted to the intensive care Unit for acute respiratory failure secondary to pulmonary edema requiring intubation and mechanical ventilation. After resolution of the acute phase, she became completely dependent on mechanical ventilatory support. In spite of the reinforcement of conventional therapy (diuretics, digitalis, vasodilators), weaning attempts were unsuccessful because of persisting elevated left atrial pressure. Percutaneous BMC was performed with favorable hemodynamic results, allowing the removal of external ventilatory support 24 h later and discharge from the intensive care Unit the same day.
