Eight patients with aneurysms of the right ventricular outflow tract patch following tetralogy of Fallot repair were found to have residual distal obstructions. The site of such an obstruction must be carefully documented preoperatively because failure to relieve significant distal obstruction may result in recurrent aneurysm formation. Chest radiography; echocardiography, including Doppler analysis; and cardiac catheterization, including angiocardiography, each have a role in the detection and evaluation of this complication.
8例法洛四联症修复术后右心室流出道补片动脉瘤患者被发现存在远端残余梗阻。术前必须仔细记录此类梗阻的部位，因为未能解除明显的远端梗阻可能导致动脉瘤复发。胸部X线摄影、超声心动图（包括多普勒分析）以及心导管检查（包括心血管造影）在该并发症的检测和评估中均发挥着作用。
