限制性和阻塞性肺病都能影响肺循环。
正常肺实质破坏引起肺动脉高压，使小动脉组织增生变厚，形成丛状病变，就如图所见的外周肺动脉分支。
Both restrictive and obstructive lung diseases can affect the pulmonary arterial circulation. The loss of normal lung parenchyma leads to pulmonary hypertension that leads to thickening of the small arteries along with reduplication to form a plexiform lesion, as seen here in a peripheral pulmonary artery.
