Vascular malformation of the small bowel is an uncommon cause of gastrointestinal haemorrhage. Phlebectasia or venous ectasia is a rare benign vascular anomaly of the gastrointestinal tract. We report a 39-year-old Egyptian man presenting with multiple jejunal phlebectasia, liver haemangioma and port-wine naevus. Despite recurrent melaena, the results of various routine investigations, including repeated endoscopic procedure, were negative. The site and aetiology of bleeding was detected using multidetector computed tomography (MDCT) angiography and was further confirmed by double-balloon enteroscopy. This report emphasises the potential of MDCT angiography in the diagnosis of small intestine lesions presenting as obscure bleeding.
小肠血管畸形是胃肠道出血的不常见原因。静脉瘤或静脉扩张是胃肠道罕见的良性血管畸形。我们报告了一位 39 岁的埃及男性，表现为多发性空肠静脉瘤、肝血管瘤和葡萄酒色斑。尽管反复出现黑便，但包括重复内镜检查在内的各种常规检查结果均为阴性。使用多排螺旋 CT 血管造影术（MDCT 血管造影术）检测到出血部位和病因，并通过双气囊小肠镜进一步证实。本报告强调了 MDCT 血管造影术在诊断以隐匿性出血为表现的小肠病变中的潜力。
