Vascular ectasia is a well-established cause of obscure gastrointestinal hemorrhage. The primary method of diagnosis is mesenteric arteriography, which demonstrates a pattern of blush or intraluminal extravasation, early venous filling and microvascular distention. The most common location for this lesion is the cecum although small bowel lesions also are recognized. The following is a case of vascular ectasia affecting the jejunum, in which undescribed microphleboliths were found on microscopic examination.
血管扩张是隐匿性胃肠道出血的一个公认原因。主要诊断方法是肠系膜动脉造影，其表现为造影剂外渗或腔内造影剂外溢、静脉早期充盈和微血管扩张的模式。尽管也发现了小肠病变，但该病变最常见的部位是盲肠。以下是一例累及空肠的血管扩张病例，在显微镜检查中发现了未描述的微静脉石。
