Bronchiectasis overview

Overview
Bronchiectasis is a disease that causes localized, irreversible dilatation of part of the bronchial tree. Involved bronchi are dilated, inflamed, and easily collapsible, resulting in airflow obstruction and impaired clearance of secretions. Bronchiectasis is associated with a wide range of disorders, but it usually results from necrotizing bacterial infections, such as infections caused by the Staphylococcus or Klebsiella species or Bordetella pertussis.

Rene Theophile Hyacinthe Laënnec, the man who invented the stethoscope, used his creation to first discover bronchiectasis in 1819. . The disease was researched in greater detail by Sir William Osler in the late 1800s; in fact, it is suspected that Osler actually died of complications from undiagnosed bronchiectasis.
