Forty-two cases of progressive systemic sclerosis were reviewed. A compression defect of the duodenum was found at the site where the superior mesenteric artery crossed the duodenum in all patients with duodenal dilatation. A similar observation was made in patients with small-intestinal obstruction and pancreatitis. Both the defect and dilatation may spontaneously disappear and return. The author concludes that in the cases studied, the compression produced by the superior mesenteric artery is secondary to dilatation and loss of muscle tone of the duodenum. It does not cause obstruction, and its presence per se does not warrant a diagnosis of "superior mesenteric artery syndrome."
回顾了42例进行性系统性硬化症患者。在所有十二指肠扩张的患者中，均在肠系膜上动脉跨过十二指肠的部位发现十二指肠受压缺损。在小肠梗阻和胰腺炎患者中也观察到类似情况。缺损和扩张可能会自发消失并恢复。作者得出结论，在所研究的病例中，肠系膜上动脉产生的压迫是十二指肠扩张和肌张力丧失的继发结果。它不会导致梗阻，其本身的存在并不足以诊断为“肠系膜上动脉综合征”。
