In the first 100 patients operated on for C T-E PH, three were referred with the diagnosis of UPAA having been made elsewhere. We found that many features of these two conditions are so similar that differential diagnosis is very difficult. Shared features may include findings on chest x-ray film, pulmonary angiography, CT scan and MRI studies. Since the two conditions vary substantially with respect to the methods of potential surgical correction, recognition of this possible differential diagnostic dilemma is important.
在最初接受慢性血栓栓塞性肺动脉高压（CT-EPH）手术的100例患者中，有3例是在其他地方被诊断为未明原因的肺动脉高压（UPAA）后转诊而来的。我们发现这两种疾病的许多特征非常相似，以至于鉴别诊断非常困难。共同特征可能包括胸部X光片、肺血管造影、CT扫描和MRI研究的结果。由于这两种疾病在潜在手术矫正方法方面有很大差异，认识到这种可能的鉴别诊断困境很重要。
