Right mainstem bronchial atresia successfully corrected with slide tracheobronchoplasty.

Mainstem bronchial atresia (MBA) is a rare and fatal entity with no survivors reported to date. We describe a neonate born at 36 weeks gestational age (GA) with right MBA who underwent successful slide tracheobronchoplasty at 32 days of life. It is theorized that during fetal life a transient fistulous connection developed, allowing right lung decompression and left lung development.
