Micro-Arteriography

Extramural and Intramural Blood-supply of Colon

“…The main branches of the short and long arteries also anastomose freely with the branches from subsequent arteries on either side, so forming a rich submucosal plexus along the circumference and length of the colon. This arterial plexus resembles that shown by Barclay (1951) to exist in the stomach. Saunders et al (1957), describing their finding of the arterial supply in skeletal muscle, showed a similar meshwork of vessels, which they termed a "macromesh," inside which there exists a further network of smaller vessels termed " micromesh," from which the arterioles supplying the capillaries arise.…”

“…Necropsy spasm occurs in all arteries within two to three hours of death (Bayliss, 1902;McWilliam and Mackie, 1908), but can be overcome by infusing the arteries with a weak solution of ammonia before the injection experiments are performed. Post-mortem clotting interferes with filling of the smaller vessels in necropsy cadavers, but this can be eliminated in postoperative specimens by infusion with normal saline solution immediately after removal.…”

Cystic arterial patterns in diseased human gall bladders.

“…There have been frequent macroscopic studies of the arteries within different organs, sometimes to show vessels which may be of significance in operative surgery or to establish the source of arterial supply, and less frequently to demonstrate special features such as arteriovenous shunts (Barclay, 1951). To date most of these studies have been confined to disease-free organs.…”

Vascular Supply of the Optic Pathway : II. Further Studies by Micro-Arteriography of the Optic Nerve

“…The branches, which derived from the very rich pial vascular network, penetrated dichotomously into the optic nerve, the septa gradually disappeared towards the intracanalicular and cranial sections, and in the centre the capillaries were less frequent and the meshwork looser (cf. also Behr, 1935).Fazio and Farina (1940) deduced from horizontal sections (not from injection) the existence of an irregular quadrangulated meshwork, orientated lengthways, built up by very small capillaries, and of equal density at the periphery and centre. Towards the optic foramen the capillaries and meshes were wider and still more irregular, and in the intracranial section a great number of very small vessels ran parallel.…”
