With the interruption of the bronchial arteries after lung transplantation, nutritive support is
dependent on collateral flow by the pulmonary arteries with desaturated venous blood.
Consequently, oxygen deficiency of the peribronchial and dependent lung tissue may occur.
Using a canine model for left lung transplantation, we investigated hypoxic peribronchial
tissue after conventional lung transplantation and demonstrated restitution of tissue
oxygenation after transplantation with bronchial artery revascularization (BAR)(BAR group …
