Sixty-five patients with angiodysplasia were studied: 42 (64.6%) had normal renal function and 23 (35.4%) had renal insufficiency, defined as serum creatinine consistently greater than 1.5 mg/dl. Comparison of results in the two groups showed that there were no significant differences in the mode of presentation or anatomic distribution of angiodysplasia. Systemic hypertension, congestive cardiac failure, coronary artery disease, and diabetes mellitus were significantly more common in patients with renal failure. Recurrent bleeding from upper alimentary angiodysplasias occurred significantly more often in patients with renal failure than in those with normal renal function. However, a second source, as a cause of bleeding, was found significantly more often in patients with normal renal function.
对65例血管发育异常患者进行了研究：42例（64.6%）肾功能正常，23例（35.4%）存在肾功能不全，定义为血清肌酐持续高于1.5mg/dl。两组结果比较显示，血管发育异常的表现方式或解剖分布无显著差异。系统性高血压、充血性心力衰竭、冠状动脉疾病和糖尿病在肾衰竭患者中明显更为常见。上消化道血管发育异常反复出血在肾衰竭患者中发生的频率明显高于肾功能正常的患者。然而，作为出血原因的第二个出血源在肾功能正常的患者中发现的频率明显更高。
