To present a unique case of vascular supply to the gastrointestinal organs as anatomical variants have variable clinical implications and must be recognized to avoid adverse outcomes.
Describe the embryological origin of vascular supply of gastrointestinal organs and present a few variants described in the literature.
On angiogram, patient was found to have total colonic supply via the inferior mesenteric artery. This is a rare anatomical variant which altered management in this child with massive lower gastrointestinal bleed due to sacral neuroblastoma metastasis and mucormycosis colitis.
Vascular anatomic variants have clinical implications that can alter management.
呈现一例独特的胃肠道器官血管供应情况，因为解剖变异具有不同的临床意义，必须加以识别以避免不良后果。
描述胃肠道器官血管供应的胚胎学起源，并介绍文献中描述的一些变异情况。
血管造影显示，该患者的整个结肠由肠系膜下动脉供血。这是一种罕见的解剖变异，改变了对这名因骶神经母细胞瘤转移和毛霉菌病性结肠炎导致大量下消化道出血的儿童的治疗方案。
血管解剖变异具有可改变治疗方案的临床意义。
