Four cases of pulmonary artery stenosis resulting from extrinsic pressure are presented. All of these cases presented with the triad of chest pain, dyspnoea, and a pulmonary systolic murmur. Respiratory variation of this murmur was noted in three of the patients, the murmur increasing during expiration and diminishing or disappearing during inspiration. It is suggested that this may be a useful sign in diagnosing this syndrome. The tumour in these four cases was an intrapericardial sarcoma, a benign teratoma, Hodgkin's disease, and a malignant thymoma respectively.
本文报告了4例因外部压迫导致肺动脉狭窄的病例。所有这些病例均表现为胸痛、呼吸困难和肺动脉收缩期杂音三联征。3例患者出现了该杂音的呼吸变化，即呼气时杂音增强，吸气时减弱或消失。提示这可能是诊断该综合征的一个有用体征。这4例患者的肿瘤分别为心包内肉瘤、良性畸胎瘤、霍奇金病和恶性胸腺瘤。
