161 – Bronchial parallelism

161 - multidrug-resistant pulmonary tuberculosis

View from the intrathoracic trachea.
These source bronchi are “reunited”.

Note that the separation angle has been reduced, giving a singular aspect of parallelism.
The posterior tracheal wall is also modified.

The changes are due to a thoracoplasty of six ribs, which has included the first, as a complementary surgical treatment for multidrug-resistant pulmonary tuberculosis.
