Fig. 4

Intraoperative findings of right pulmonary artery. The pulmonary artery (PA) wall was incised at the anastomosis and the upper portion of PA wall was thickened and protruded into the lumen. Arrows indicate thickened pulmonary artery walls (a). This thickened PA wall was resected (b) and the resected wall section was anastomosed between the graft and the recipient's PA wall. The initially incised PA wall was reconstructed with an autologous pericardial patch. Arrows and dotted lines indicate the pericardial patch (c)
