aIf stenosis existed, the PA was measured at the level of the hilus of the lung; we used this diameter to calculate the Nakata index and McGoon ratio. Five patients with an approximately satisfactory PA development index but extremely diminutive PA on one side were also included in our procedure (shown in Fig. 1).
