Morphometric study of the pulmonary vasculature was performed on lung biopsy specimens from a one-year-old girl who underwent anatomic repair of isolated aortic origin of the right pulmonary artery. Medial hypertrophy of small pulmonary arteries in the right lung was much less remarkable than that in the left lung. In contrast, intimal lesions in the right lung were much more advanced than those in the left lung. Fully oxygenated blood in the right pulmonary artery might suppress medial hypertrophy in response to high pressure and thin media fail to protect intima from high pressure, resulting in severe intimal lesions. This situation in the right lung resembles that in complete transposition of the great arteries.
对一名一岁女童的肺活检标本进行了肺血管系统的形态计量学研究，该女童接受了右肺动脉孤立性主动脉起源的解剖修复术。右肺小肺动脉的中膜肥厚比左肺轻得多。相比之下，右肺的内膜病变比左肺严重得多。右肺动脉中充分氧合的血液可能会抑制因高压引起的中膜肥厚，而变薄的中膜无法保护内膜免受高压影响，从而导致严重的内膜病变。右肺的这种情况与大动脉完全转位的情况相似。
