肺静脉闭塞是引发肺动脉高压的一种非常少见的原因,其诊断和治疗都非常困难。临床用于治疗原发肺动脉高压的前列腺素静脉输入或雾化吸入法对肺静脉闭塞病人无益甚至会引起病人死亡。因此,区分肺静脉闭塞引发的肺动脉高压与原发肺动脉高压非常重要。作者通过对2组疾病的配对研究 Pulmonary vein occlusion is a very rare cause of pulmonary hypertension, its diagnosis and treatment are very difficult. Prostaglandin infusion or nebulization, which is clinically used to treat primary pulmonary hypertension, is of no benefit to patients with pulmonary vein occlusion and may even cause death. Therefore, the distinction between pulmonary venous occlusion caused pulmonary hypertension and primary pulmonary hypertension is very important.
