3. Fibrous occlusion and anastomosis of longitudinal muscle in the arterial media reinforce such a theory (Wade and Ball, I957; Heath and;Brewer, D.B.;Journal of Pathology and Bacteriology; These mechanisms probably the pulmonary vessels in a case of pulmonary hypertension associated with patent ductus arteriosus,1955
4. Relation of structure to function of the tissues of the wall of blood vessels. Physiological Reviews, result in increased mechanical rigidity of the vessel wall, as postulated by Burton 1954;Burton, A.C.,1954
5. modes of evolution of the dilatation lesions is by recanalization of the pulmonary arteries. It seems that the recanalized channels acquire a muscular wall of their own, out of a haemodynamic;necessity, Denst; J., Edwards; A., Neubuerger; T., K.; Blount, S.G.;American Heart37ournal; Biopsies of the lung and atrial appendages in mitral stenosis: correlation of data from cardiac catheterization with pulmonary vascular lesions,1954
