To expand the search for central pulmonary arteries in six patients with absence of cardiac-pulmonary continuity, computerized axial tomography (CAT) of the chest was performed. The CAT scans were compared with previous arteriograms and pulmonary vein wedge angiograms. Three patients with type IV truncus arteriosus were studied, and none had a central, right or left pulmonary artery on CAT scan. However, two patients with tetralogy of Fallot with pulmonary atresia and a patent ductus arteriosus to the right lung demonstrated the presence of a left pulmonary artery. In addition, one child with truncus arteriosus with "absent" left pulmonary artery demonstrated a left pulmonary artery on the CAT scan. The CAT scan may therefore enhance our ability to search for disconnected pulmonary arteries in children with complex cyanotic congenital heart disease.
为了在6例心肺连续性中断的患者中寻找中央肺动脉，对其进行了胸部计算机断层扫描（CAT）。将CAT扫描结果与之前的动脉造影和肺静脉楔入造影进行了比较。研究了3例IV型永存动脉干患者，CAT扫描均未发现中央、右侧或左侧肺动脉。然而，2例法洛四联症合并肺动脉闭锁且动脉导管未闭至右肺的患者显示存在左肺动脉。此外，1例永存动脉干合并“缺如”左肺动脉的患儿在CAT扫描中显示有左肺动脉。因此，CAT扫描可能会增强我们在患有复杂青紫型先天性心脏病的儿童中寻找离断肺动脉的能力。
