平原人移居高原后因高原低氧性肺小动脉收缩可引起肺动脉压增高,随后可出现肺小动脉肌化,管径变细等器质性改变。但反映这种改变的肺动脉造影的影象学研究尚未见报道,现将作者观察的3例报告于下。1 对象 3例均为高原心脏病的男性患者,年龄30～48岁(39.3±9.0),生活海拔高度3730～4260米(4003.3± Plain people migrate to plateau due to plateau hypoxic pulmonary arterial contraction can cause increased pulmonary arterial pressure, followed by the occurrence of pulmonary arterialization, smaller diameter and other mechanical changes. However, this change of pulmonary angiography imaging studies have not been reported, now the author observed in 3 cases reported below. 1 Subjects 3 cases were male patients with plateau heart disease, aged 30 to 48 years (39.3 ± 9.0), living altitude 3730 ~ 4260 meters (4003.3 ±
