Unifocalisation procedure

Last revised by Craig Hacking on 27 Jul 2022

A unifocalisation procedure is a corrective surgical technique used in patients with complete pulmonary artery atresia with major aortopulmonary collateral arteries (MAPCAs). In this technique, the collateral vessels supplying blood from the aorta directly to the lungs are brought into continuity in a single vessel that supplies the pulmonary circulation usually via a conduit from the right ventricle or a shunt.
