摘要
慢性高原病(chronic mountain sickness,CMS)患者主肺动脉(main pulmonary artery,MPA)扩张发生发展的核心和关键是慢性高原低压性缺氧,其次是寒冷。且两者的复合作用可增强其对心血管系统的影响。影像学检查不仅可以有效地诊断MPA扩张,还能评价其与肺动脉高压的关系以及评估其对心脏的影响。在诸多的检查中,MRI占有不可替代的位置。作者主要针对CMS患者MPA扩张的发病机理、临床意义及影像诊断进行综述。
The mian causes of main pulmonary artery（MPA） dilatation in patients with chronic mountain sickness（CMS） is chronic plateau hypoxia, followed by cold. The combined action of both can affect the function of cardiovascular system. Imaging examination not only can effectively diagnose MPA dilatation, but also evaluate the relationship between MPA dilatation and pulmonary arterial hypertension or the effect of MPA dilatation on the heart. MRI plays an irreplaceable role in such examinations. This paper reviews the pathogenesis, clinical significance and imaging diagnosis of MPA dilatation in patients with CMS.
