We have searched for any abnormalities of the pulmonary arteries visualized by angiography in 200 consecutive patients with tetralogy of Fallot. All the patients were studied by conventional right ventricular angiography in the right and left anterior oblique views. Thirty six patients (18%) showed a total of 61 pulmonary artery stenoses, 32 being severe (52%), 17 moderate (28%) and 12 mild (20%). Bifurcational stenoses were the most common (31), followed by stenosis of the main pulmonary trunk, the right or the left pulmonary arteries (22), combined central and peripheral stenosis (6), and isolated peripheral pulmonary artery stenosis (2). Nine patients showed segmental stenosis involving both the right and left pulmonary arteries and three of them had atresia of the left pulmonary artery. The detailed preoperative evaluation of obstruction within the pulmonary arterial pathways is essential in tetralogy of Fallot to ensure normalisation of the right ventricular pressure following total correction.
我们在200例法洛四联症患者中，通过血管造影术寻找肺动脉的任何异常情况。所有患者均接受了常规右心室造影，包括右前斜位和左前斜位。36例患者（18%）共出现61处肺动脉狭窄，其中重度32处（52%），中度17处（28%），轻度12处（20%）。分叉处狭窄最为常见（31处），其次是主肺动脉、右或左肺动脉狭窄（22处），中央和外周联合狭窄（6处），以及孤立的外周肺动脉狭窄（2处）。9例患者出现累及左右肺动脉的节段性狭窄，其中3例左肺动脉闭锁。在法洛四联症中，对肺动脉通路内梗阻进行详细的术前评估对于确保完全矫正后右心室压力正常化至关重要。
