Latex rubber was perfused into the abdominal aorta of 10 healthy dogs. Each kidney was found to have 4 to 6 vascular extensions of interlobar or arcuate arteries which communicated with an extrarenal artery. Renal collateral arterial connections were made with the phrenicoabdominal, spermatic, deep circumflex iliac, ureteral, caudal mesenteric, lumbar, and adrenal arteries. The renal collateral circulation was stimulated in 4 dogs by gradual compression of the renal artery and the presence of hypertrophied vessels confirmed by angiography. In 1 of these 4 dogs, the right renal artery was gradually compressed and finally occluded. Subsequently, contralateral nephrectomy was performed. Nine weeks later, the dog was still active, alert, and eating well.
将乳胶橡胶灌注到10只健康犬的腹主动脉中。发现每个肾脏都有4至6个叶间动脉或弓形动脉的血管分支，这些分支与肾外动脉相通。肾侧支动脉连接是通过膈腹动脉、精索动脉、旋髂深动脉、输尿管动脉、肠系膜后动脉、腰动脉和肾上腺动脉建立的。通过逐渐压迫肾动脉刺激4只犬的肾侧支循环，并通过血管造影证实存在肥大的血管。在这4只犬中的1只，右肾动脉逐渐被压迫并最终闭塞。随后，进行了对侧肾切除术。9周后，这只犬仍然活跃、警觉且食欲良好。
