22 children got lung scans 3 weeks respectively 12 months after the correction of a tetralogy of Fallot. In 18 cases previous operations were done: 12 times a Blalock-Taussig shunt and 6 times a Brock procedure. For the scan 20-70 mu diameter albumin macrospheres were used, which were labeled with Technetium 99m. The following pathologicla lung changes were seen: 1. Loss of perfusion, typical after Blalock-Taussig shunt procedure; these findings were always on the left side, the site of the anastomosis. 2. Anomalous flow distrubution (=more spheres in the upper than in the lower lobe) in the left lung; these changes were also caused by the Blalock-Taussing shunts, but disappeared within the one year follow-up after the correction. 3. Intrapulmonary rigt-left shunts (according to the dilatation of the alveolar capillaries). These decreased within one year from 9.9+/-1.3 to 4.6+/-0.9%.
22名儿童在法洛四联症矫正术后3周及12个月分别接受了肺部扫描。18例曾接受过手术：12例行布劳克-陶西格分流术，6例行布罗克手术。扫描时使用了直径为20 - 70微米的白蛋白微球，并用99m锝进行标记。观察到以下肺部病理改变：1. 灌注缺失，这在布劳克-陶西格分流术后很典型；这些表现总是出现在左侧，即吻合部位。2. 左肺血流分布异常（=上叶的微球比下叶多）；这些改变也是由布劳克-陶西格分流术引起的，但在矫正术后一年的随访中消失。3. 肺内右向左分流（根据肺泡毛细血管扩张情况）。这些分流在一年内从9.9±1.3%降至4.6±0.9%。
