Consider the position of the tracheal anastamoses (usually heart-lung transplants) or bronchial anastamoses (usually lung only transplants).

When positioning an endotracheal tube in tracheal anastamoses place the cuff just beyond the vocal cords to minimise the risk of traumatising the anastamosis.

If inserting a DLT in a patient with bronchial anastamoses visualising the anastamoses with a flexible bronchoscope is essential.

Lung transplants utilise bronchial anastomoses, tracheal anastomosis is only used now for heart-lung transplants. Endotracheal intubation as normal but if inserting a double lumen tube use of a fibre optic bronchoschope to check position is essential.
Good points, thanks Derek
Lung denervation ablates afferent sensation below the level of the tracheal anastamosis. Patients lose the cough reflex & are prone to retention of secretions & silent aspiration. refl.in/72

If placing a double lumen tube, place the endobronchial lumen in native lung to avoid damage to anastmosis. refl.in/72
