It can be difficult to judge the degree of arborization of diminutive central pulmonary arteries (cPA) in patients with major aortopulmonary collateral arteries (MAPCA). Even through preoperative cardiac catheterization may not give adequate information. We introduce intra-operative direct angiography of diminutive cPA for patients with MAPCA. This would be one of the good options to judge the degree of arborization of the diminutive cPA, and to decide an initial surgical treatment. In this case, unifocalization of MAPCA without patch augmentation of pulmonary arteries, and an aortopulmonary shunt were performed at the 1st procedure. As enough growth of the cPA was obtained, this patient did not require additional patch augmentation of the pulmonary artery at the time of complete repair.
