Notizen: Summary Lung tissue from 14 normal residents of high altitude regions, 10 patients with chronic bronchitis and emphysema, and 1 patient with Pickwickian syndrome was studied with regard to the occurrence of pulmonary vascular changes. In addition to the well-known pulmonary arterial alterations, lesions in small pulmonary veins were found in the great majority of the cases. These changes, consisting of medial hypertrophy and arterialization and of bundles of smooth muscle cells within the venous intima, have not been described before in man. These findings suggest that alveolar hypoxia acts not only on small pulmonary arteries and arterioles but also on veins of small caliber, probably by inducing venoconstriction.
