Seven patients were evaluated by radionuclide angiography (RNA) following Fontan-like procedures for complex cyanotic congenital defects. Both first-pass and ECG gated equilibrium angiography were performed in each. Residual right-to-left shunts, right atrial (RA) outflow and pulmonary arterial obstruction, and left ventricular dysfunction were demonstrated by these techniques. In addition, RA ejection fraction (RAEF) by gated equilibrium scan was measured in each patient. Relatively low RAEF was seen in conjunction with residual obstruction to pulmonary flow. RNA is useful in the postoperative evaluation of patients after Fontan procedures.
对7例患有复杂紫绀型先天性缺陷并接受类Fontan手术的患者进行了放射性核素血管造影（RNA）评估。对每位患者均进行了首次通过法和心电图门控平衡血管造影。这些技术显示了残余的右向左分流、右心房（RA）流出道和肺动脉梗阻以及左心室功能障碍。此外，通过门控平衡扫描测量了每位患者的RA射血分数（RAEF）。发现相对较低的RAEF与肺血流残余梗阻有关。RNA对Fontan手术后患者的术后评估很有用。
