A new conception concerning the angioarchitectural organization of the canine kidney.
The sublobular artery arises from the arcuate artery, as a constant vessel possessing its proper personality, giving 2 equal subdivisions, from which part the interlobular arteries. The sublobular arteries are characterized by a particular origin and branching type, having no or sporadically disposed glomeruli. Occasionally, arteriae interlobulares derive directly from the arcuate artery too. The authors suggest the acception of term "Arteria sublobularis " in the international nomenclature of the renal vessels. According our opinion the canine kidney is composed of a number of conical units, containing in their axis a sublobular artery of 2nd order. Certain theoretical and practical aspects of this new conception are briefly discussed.
