Objective To analyze the growth of anastomotic stoma of aortic(AO) and p
ulmonary artery (PA) after arteries switch operation(ASO) so as to assess the longterm efficacy of ASO . Methods The data of 331 patients who had undergone ASO in Shanghai Children’s Medical Center of Jiaotong University from December 1999 to December 2007 was analysed retrospectively. One hundred eleven patients had complete transposition of great arteries complicated with intact ventricular septum(TGA/IVS), 123 had complete transposition of great arteries complicated with ventricular septal defect(TGA/VSD), 73 had TaussigBing complicated with ventricular septal defect and pulmonary hypertension, and 24 underwent StageSwitch. Of the 331 patients 228 were followedup, and the followup time was 20.4±18.6 months. There were 752 ultrasonic cardiograph reports, 3.3
per patient on average. The growth of anastomosis was analysed according to the diameters of AO and PA. Results The AO and PA anastomosis diameters of TGA/IVS patients（before discharge 0.74±0.17 cm and 0.65±0.13 cm, latest followup 1.09±0.31cm and 0.84±0.21 cm）, TGA/VSD patients (before discharge 0.76±0.20 cm and 0.63±0.14 cm, latest followup 1.09±0.24 cm and 0.82±0.22 cm) and TaussigBing patients（before discharge 0.84±0.25 cm and 0.74±0.20 cm, latest followup 1.05±0.30 cm and 0.85±0.24 cm） growed significantly（P lt;0.05）. The AO anastomotic stoma diameters of patients who had underwent StageSwtich (before discharge 0.93±0.19 cm, latest followup 1.19±0.29 cm) growed significantly（P lt;0.05）. The PA anastomotic stoma diameter growed（before discharge 0.90±0.27 cm, latest followup 1.00±0.32 cm）, but had no statistical significance (P＞0.05). Till November 2008, Six patients needed reoperation because of the right or left ventricle outflow tract obstruction. After reoperation, 3 had no residual obstruction, 3 had residual obstruction. Conclusion After the section and suture of ASO, aortic and pulmonary artery can grow with age, but sometimes stenosis happens to some patients. During the followingup, some patients need reoperation.
