Because multiple lesions, including colonic malignancies, vascular lesions of the colon, and diverticuli may coexist, identifying the cause of lower gastrointestinal bleeding in an elderly patient can be difficult. A case that demonstrates this clinical problem is reported. Right-sided colonic vascular ectasia eventually was detected angiographically and was treated successfully with hemicolectomy. Colonic vascular ectasia is an increasingly recognized cause of gastrointestinal hemorrhage. The pathologic findings, proposed theories of pathogenesis, and clinical association between colonic vascular ectasia and aortic stenosis are discussed.
由于包括结肠恶性肿瘤、结肠血管病变和憩室在内的多种病变可能同时存在，因此确定老年患者下消化道出血的病因可能很困难。本文报告了一个说明这一临床问题的病例。右侧结肠血管扩张最终通过血管造影检测到，并通过半结肠切除术成功治疗。结肠血管扩张是一种越来越被认可的胃肠道出血原因。本文讨论了结肠血管扩张的病理表现、发病机制的理论以及与主动脉瓣狭窄的临床关联。
