Percutaneous, intraarterial traumatization of both renal arteries in 4 pigs using the stiff end of a guide-wire resulted in intimal lesions in 7 arteries. At repeat angiography healing was demonstrated in 4 of these arteries, suggesting that spontaneous restitution may be more common than usually believed. Balloon catheter dilatation of 2 stenotic segments initially increased the diameter of the stenoses but at repeat angiography both arteries were found to be occluded. Over-distension of the balloon in the renal artery resulted in pseudoaneurysm in one case and rupture in the other.
使用导丝硬端对4头猪的双侧肾动脉进行经皮动脉内创伤，导致7条动脉出现内膜损伤。在重复血管造影时，其中4条动脉显示有愈合迹象，这表明自发修复可能比通常认为的更为常见。对2处狭窄节段进行球囊导管扩张，最初使狭窄直径增加，但在重复血管造影时发现两条动脉均闭塞。肾动脉球囊过度扩张，1例导致假性动脉瘤，另1例导致破裂。
