Lung Transplant From Donor With Tracheal Bronchus: Case Report and Literature Review.

Donor lung abnormalities are quite rare; one of them is the presence of bronchial anomalies, whose incidence range is from 0.1% to 0.5%. The upper right tracheal bronchus is one of the most frequent anatomic variations. We present a case of successful double lung transplant in a young female patient affected by cystic fibrosis from a donor with upper right tracheal bronchus, emerging 2 rings before the tracheal carina. During implantation of the left lung, we performed a double apical segmentectomy on back table; therefore, the right lung was implanted with the standard technique. Four cases of graft transplant characterized by the presence of tracheal bronchus are reported in the scientific literature; the authors report 4 different technical solutions to tackle the problem of anatomic anomaly. We report the first case of graft segmentectomy at back table suggesting a simple, safe, and time-sparing procedure. In conclusion, provided that the team has sufficient skill in reductive surgery at the back table and the anthropometric data are permissive, we stress the opportunity to downsize the graft in order to minimize anastomotic risks and save time.
