Angiographies (a total of approximately 9 500) and patient records revealed 56 patients with renal artery aneurysm during the period 1960 to 1974. Fifteen patients were operated upon electively and 3 were lost for follow-up. Rupture occurred in four leading to acute nephrectomy. Thus, 34 patients were left for studies on the natural course. They were 29-82 years old (mean 58 years) at diagnosis and were followed for at least 90 months. Twelve were males and 22 females. The aneurysms had a diameter of 3-25 mm (mean 12 mm), were fusiform in 7 and saccular in 27 cases; 9 were calcified. Repeated angiographies were carried out in 7 patients at intervals of up to 73 months showing slight enlargement of one aneurysm, disappearance of another and no change in 5. Sixteen patients were alive at the end of the follow-up period 90-220 months (mean 157 months) after the first or only angiography. Eighteen patients died after 2-204 months (mean 84 months), 14 of cardiovascular disease unrelated to the renal arteries, 3 of malignant tumour and one of pancreatitis. Autopsy in 12 patients did not show rupture of any renal artery aneurysm. Thus, in a considerable number of patients the disorder was uncomplicated and compatible with a long life.
血管造影（共约9500例）及患者记录显示，1960年至1974年期间有56例肾动脉动脉瘤患者。15例患者接受了择期手术，3例失访。4例发生破裂，导致急性肾切除术。因此，留下34例患者进行自然病程研究。他们诊断时年龄为29 - 82岁（平均58岁），随访至少90个月。男性12例，女性22例。动脉瘤直径为3 - 25毫米（平均12毫米），7例为梭形，27例为囊状；9例有钙化。7例患者每隔73个月进行一次重复血管造影，结果显示一个动脉瘤略有增大，另一个消失，5个无变化。随访期结束时，即首次或仅有的一次血管造影后90 - 220个月（平均157个月），16例患者存活。18例患者在2 - 204个月（平均84个月）后死亡，14例死于与肾动脉无关的心血管疾病，3例死于恶性肿瘤，1例死于胰腺炎。12例患者的尸检未显示任何肾动脉动脉瘤破裂。因此，在相当多的患者中，该疾病并不复杂，与长寿相符。
