The triad of bridging bronchus malformation associated with left pulmonary artery sling and narrowing of the airway: the legacy of Wells and Landing.

Although noted in the 19th century, it was not until 1938 that Scheid published the combination of left pulmonary artery sling and narrowing of the airway due to annular tracheal cartilages. Unaware of these prior descriptions, and without a precise preoperative diagnosis, Willis Potts in Chicago performed the first successful sling repair in 1953. In 1976, Cohen and Landing described Scheid's combination of left pulmonary artery sling and stenosis caused by complete tracheal rings, and the term "ring-sling complex" was introduced by Berdon in 1984. Four years later, Wells and Landing noted characteristic tracheobronchial malformations associated with these lesions and proposed a classification that has been confirmed to be clinically relevant in recent cross-sectional imaging studies.

Tracheal Injuries Complicating Prolonged Intubation and Tracheostomy.

Respiratory care advances such as the introduction of ventilatory assistance have been associated with postintubation airway stenosis resulting from tracheal injury at the site of the inflatable cuff on endotracheal or tracheostomy tubes. Low-pressure cuffs have significantly reduced this occurrence. Loss of airway stability at the site of a tracheostomy stoma may result in tracheal stenosis. Subglottic stenosis may result from a high tracheostomy site at, or just inferior to, the cricoid arch, or to malposition of an endotracheal tube cuff. Awareness of these complications and their causes is essential to prevent their occurrence.

Tracheobronchoplasty in Japan.

More than a century has passed since the first tracheoplasty was successfully performed by Eiselsberg in 1896. In that time, tracheobronchoplasty has developed with the extension of operative indications. This review focuses on who contributed to the development of this operation in Japan, and in what ways, with comparisons to results for these operations in the West. The headings include "Pioneers and colleagues", "Symbols and taxonomy", "Surgical anatomy", "Surgical diseases", "Anesthesia", "Surgical techniques", "Results", and "The present state". Although effort has been made to acknowledge various opinions, the convictions expressed herein are my own.

The history of tracheal surgery.

Tracheal surgery, which did not exist in a coherent, systematic fashion 45 years ago, has developed techniques that allow resection of approximately half of the adult trachea with primary reconstruction, largely by anatomic mobilization procedures. Dependable methods have also been developed for laryngotracheal and carinal resection and reconstruction. The daunting problem of long congenital tracheal stenosis appears to be largely solved by slide tracheoplasty. In the past four decades much has also been learned about the etiology, natural history, pathology, and (in some cases) prevention of tracheal diseases including primary and secondary tumors, postintubation injuries, and idiopathic stenosis.
