Lung transplant with bronchial arterial revascularization: review of surgical technique and clinical outcomes

The bronchi have a dual blood supply from (I) bronchial arteries, which originate from the aorta, and (II) pulmonary arterial circulation. Experimental lung transplantation (LTx) with bronchial arterial revascularization (BAR) is credited to Metras in the 1950s and Haglin in the 1970s (1,2). Successful BAR improved early airway healing, and decreased airway complications (1,2)
