Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction resulting from compression of the duodenum by the superior mesenteric artery and abdominal aorta.
We describe a case of superior mesenteric artery syndrome in a 61-year-old Japanese man with non-small cell lung cancer who had been treated with cisplatin-containing chemotherapy and had lost 7 kg in weight. The diagnosis was confirmed by the typical findings of abdominal computed tomography showing distended stomach resulting from compression of the third portion of the duodenum and reduction of an aortomesenteric distance and aortomesenteric angle.
This case highlights the importance of considering the possibility of superior mesenteric artery syndrome in patients treated with chemotherapy, especially those presenting with a low body mass index and showing weight loss during chemotherapy.
肠系膜上动脉综合征是一种罕见的上消化道梗阻病因，由肠系膜上动脉和腹主动脉压迫十二指肠所致。
我们描述了一例61岁日本男性的肠系膜上动脉综合征病例，该患者患有非小细胞肺癌，接受了含顺铂的化疗，体重减轻了7公斤。腹部计算机断层扫描的典型表现证实了诊断，显示十二指肠第三部受压导致胃扩张，以及腹主动脉肠系膜距离和腹主动脉肠系膜角减小。
本病例强调了在接受化疗的患者中，尤其是那些体重指数低且在化疗期间出现体重减轻的患者，考虑肠系膜上动脉综合征可能性的重要性。
