Superior mesenteric venous occlusion may be difficult to recognize, but is important as it carries a better prognosis than superior mesenteric arterial occlusion, an may be amenable to surgical treatment. Three cases of primary superior mesenteric venous occlusion are described. The diagnosis was unsuspected until discovered at laparotomy. Non-viable bowel was present in all cases and in two cases thrombosed veins were apparent in the mesentery. The lesion was localized in distribution, and generous bowel resection with primary anastomosis was performed. Recovery was uncomplicated in all cases. When the thrombosis appears well localized, generous resection with primary anastomosis seems a suitable alternative to resection and exteriorization or conservative treatment with a second-look procedure.
肠系膜上静脉闭塞可能难以识别，但很重要，因为它的预后比肠系膜上动脉闭塞要好，且可能适合手术治疗。本文描述了3例原发性肠系膜上静脉闭塞病例。在剖腹手术前诊断均未被怀疑。所有病例均存在肠坏死，2例在肠系膜中可见血栓形成的静脉。病变分布局限，行广泛肠切除并一期吻合。所有病例恢复过程均无并发症。当血栓形成似乎局限时，广泛切除并一期吻合似乎是切除并外置或二期探查保守治疗的合适替代方法。
