29 mongrels were subjected to splenic artery implantation into the left kidney. Consecutive angiographies showed that this procedure regularly was followed by an initial thrombus formation in the implanted artery and an early recanalization of this thrombus. After creation of stenosis and eventually occlusion of the left renal artery, newly formed intrarenal vessels could be demonstrated next to the implanted artery. These vessels formed communications between the splenic and intrarenal arteries. At angiography of the implanted splenic artery the constrast medium was seen to pass over to the newly formed vessels and to intrarenal arteries followed by contrast medium opacification of the renal parenchyma and the renal vein and excretion to the pelvis and ureter. The experimental animals survived contralateral nephrectomy and ligature of the ipsilateral renal artery provided that a slowly progressing stenosis of this artery was created.
29只杂种犬接受了脾动脉植入左肾的手术。连续血管造影显示，该手术通常会在植入动脉中先形成血栓，然后血栓早期再通。在左肾动脉形成狭窄并最终闭塞后，可在植入动脉旁显示新形成的肾内血管。这些血管在脾动脉和肾内动脉之间形成了交通。在植入脾动脉的血管造影中，可见造影剂流入新形成的血管和肾内动脉，随后肾实质、肾静脉出现造影剂充盈，造影剂排泄至肾盂和输尿管。如果对侧肾切除且同侧肾动脉缓慢进展性狭窄，实验动物可存活。
