Superior mesenteric vein thrombosis was identified on computed tomographic scans in six patients. In each case, contrast-enhanced scans showed a high-density superior mesenteric vein wall surrounding a central filing defect. Four of the six patients had isolated superior mesenteric vein thrombosis. A fifth patient had associated portal vein and splenic vein thrombosis, and the sixth patient had associated portal vein and inferior vena cava thrombosis. The diagnosis of superior mesenteric vein thrombosis was confirmed by angiography in two patients and by surgery in a third. One of the six patients had acute ischemic bowel disease. The other five patients did not have acute ischemic bowel symptoms associated with their venous occlusion. This study defines the computed tomographic appearance of mesenteric vein thrombosis. A dense venous wall surrounding a central lucency representing blood clot was present in all six cases.
六名患者经计算机断层扫描确诊为肠系膜上静脉血栓形成。在每例病例中，增强扫描显示高密度的肠系膜上静脉壁环绕着中央充盈缺损。六名患者中有四名患有孤立性肠系膜上静脉血栓形成。第五名患者合并门静脉和脾静脉血栓形成，第六名患者合并门静脉和下腔静脉血栓形成。两名患者通过血管造影确诊肠系膜上静脉血栓形成，第三名患者通过手术确诊。六名患者中有一名患有急性缺血性肠病。其他五名患者没有与其静脉闭塞相关的急性缺血性肠病症状。本研究明确了肠系膜静脉血栓形成的计算机断层扫描表现。所有六例病例均可见围绕代表血凝块的中央透亮区的致密静脉壁。
