We present a case to illustrate that pulmonary artery malformation is a potential diagnosis in patients with nonresolving perfusion defects. The diagnosis can usually be made by the history, physical examination, chest roentgenogram, and ventilation-perfusion scanning. If the patient's clinical symptoms are inconsistent with the scan, then pulmonary angiography is warranted. Pleuritic chest pain, hypoxemia, and a perfusion defect are nonspecific and should not be interpreted as indicative of pulmonary embolism but only that it has not been ruled out. Anticoagulation is risky because these patients are already at increased risk for pulmonary hemorrhage and hemoptysis.
我们呈现一个病例以说明，肺动脉畸形是灌注缺损持续不缓解患者的一种潜在诊断。通常可通过病史、体格检查、胸部X线片及通气-灌注扫描做出诊断。如果患者的临床症状与扫描结果不一致，则有必要进行肺血管造影。胸膜炎性胸痛、低氧血症和灌注缺损是非特异性的，不应被解释为提示肺栓塞，而仅表明尚未排除肺栓塞。抗凝治疗存在风险，因为这些患者已经有发生肺出血和咯血的风险增加。
