title: Intrarenal arterial collateral circulation.
abstract: In three cases of intrarenal arterial collateral circulation the collateral channels developed between interlobar arteries in diseased kidneys. Probably these originated in hypertrophied spiral vessels that had arisen from the interlobar arteries in the area of the minor calyces. This form of collateral circulation will undoubtedly be recognized more frequently with the increased use of magnification radiography.
