Abstract

OBJECTIVE

To investigate the positive association between the presence of simple renal cysts (SRCs) and abdominal aortic aneurysm (AAA).

METHOD

In a retrospective case-control study including subjects aged > 50 years, we evaluated the incidence of SRCs on computed tomography (CT) scan. We compared 91 consecutive patients with AAA referred from the Division of Vascular Surgery and 396 patients without AAA, randomly selected after being matched by age and gender from 3,186 consecutive patients who underwent abdominal CT. SRC was defined as a round or oval low-attenuation lesion with a thin wall and size > 4 mm on CT without obvious evidence of radiographic enhancement or septations. Patients were considered as having AAA if the size of aorta was greater than 3.0 cm.

RESULTS

Patients with AAA and without AAA were similar in terms of age (67.9± 8.41 vs. 68.5±9.13 years) (p=0.889) and gender (71.4 vs. 71.2% of male subjects, respectively) (p=0.999). There was no difference in the prevalence of SRC between case and controls. Among individuals with AAA, 38 (41.8%; [95CI 32.5-52.6]) had renal cysts compared to 148 (37.4%; [95CI 32.7-42.2]) in the control group (p=0.473), with a prevalence ratio (PR) of 1.16 (95CI 0.80-1.68).

CONCLUSION

We found no significant differences in the prevalence of SRCs among patients with AAA and controls. Our findings suggest that the presence of SRCs is not a risk factor or a marker for AAA.

摘要

目的

探讨单纯性肾囊肿（SRC）与腹主动脉瘤（AAA）之间的正相关关系。

方法

在一项纳入年龄大于50岁受试者的回顾性病例对照研究中，我们评估了计算机断层扫描（CT）上SRC的发生率。我们比较了血管外科转诊的91例连续AAA患者和396例无AAA患者，后者是从3186例连续接受腹部CT检查的患者中按年龄和性别匹配后随机选取的。SRC定义为CT上圆形或椭圆形的低密度病变，壁薄，大小>4mm，无明显影像学强化或分隔证据。如果主动脉直径大于3.0cm，则患者被认为患有AAA。

结果

AAA患者和无AAA患者在年龄（67.9±8.41岁 vs. 68.5±9.13岁）（p=0.889）和性别（男性受试者分别为71.4%和71.2%）（p=0.999）方面相似。病例组和对照组之间SRC的患病率没有差异。在AAA患者中，38例（41.8%；[95%置信区间32.5 - 52.6]）有肾囊肿，而对照组中有148例（37.4%；[95%置信区间32.7 - 42.2]）（p=0.473），患病率比（PR）为1.16（95%置信区间0.80 - 1.68）。
