SUMMARY1 In nineteen rabbits subjected to left renal arterial ligation it was demonstrated by neoprene injection that the collateral circulation followed three main pathways. The most important involved dilated ureteric branches of the renal artery. The second involved one or two perihilar branches of the renal artery which anastomosed with branches of the lumbar arteries. In twelve instances the kidneys possessed perforating capsular vessels which anastomosed with arteries of the perirenal region. 2 The number of collateral vessels after two and six weeks was no greater than after one week. 3 The size of the vascular tree depended upon the extent of the collateral circulation and decreased from approximately one‐third the size of the controls at one week to approximately one‐fifth the size of the controls at six weeks. The preservation of glomeruli was discussed.
