The Ageing and Collateral Peripheral Artery

Hypertension and arterial development. Long-term considerations.

“…Earlier morphological studies of human arteries during ageing (Wright, 1963;Dible, 1964) emphasised that vessels may respond to haemodynamic changes by change in structure until relatively late in life and show that degenerative changes occur commonly from the early part of the third decade. More recent studies show that alteration in vessel form is more readily produced in early life; banding of the pulmonary artery in patients with high pulmonary blood flow produces a very different wall thickness proximal and distal to the band within 10 days of operation (Berry, 1969;Stark et al, 1972; and see Fig.…”

A critical survey of techniques for arterial mensuration

“…2).The cross-sectional area of the media has been mathematically calculated by some workers (Short and Thomson; Wagenvoort, 1960;Elliott;Short, 1966) from micrometer measurements of injected arteries. Others have measured the medial area directly with a planimeter (Suwa et al, 1961, quoted by Furuyama; Furuyama, 1962;Barrett, 1963;Dible, 1964;Naeye, 1965Naeye, , 1967) on tracings of projected images, on magnified photomicrographs and on the images produced by a microscope camera lucida. Barrett not only carried out planimetric measurements of the undistended five largest branches of the superior mesenteric artery at necropsy, but also, using the mean of eight observations, directly measured medial thickness.…”
