Size matching in lung transplantation: A narrative review

The risks of primary graft dysfunction, additional airway complications (due to a bronchial diameter mismatch), persistent pleural effusion, infection, hyperinfl ation of the lung, elevated risk of operative bleeding, greater acute lung injury (due to higher tidal volume during mechanical ventilation), and the development of greater pulmonary vascular resistance are higher in cases involving extremely small donor lungs [2,3].
