The aim of this study was to review the literature regarding collateral mesenteric circulation with emphasis on the mesenteric meandering artery (of Moskowitz). Standard vascular embryology and anatomy are described as are the collateral mesenteric vessels that can develop with arterial stenosis or occlusion. A discussion on the correct usage of terms for describing mesenteric collateral vessels follows.
We undertook review of the historical literature to discuss the surgical implications of the meandering mesenteric artery.
Despite a long history of study by anatomists and surgeons, confusion still persists regarding both the number and correct descriptive terminology of the collateral mesenteric vessels.
The use of the vague historic term "arc of Riolan" should be discarded for the more precise term "meandering mesenteric artery." The meandering mesenteric artery should routinely be preserved in all surgical procedures, to include resection for cancer, given its critical function in providing collateral mesenteric circulation. Further evaluation in the asymptomatic patient, however, is unnecessary.
本研究旨在回顾有关肠系膜侧支循环的文献，重点关注（莫斯科维茨）肠系膜迂曲动脉。描述了标准的血管胚胎学和解剖结构，以及在动脉狭窄或闭塞时可能发育的肠系膜侧支血管。随后讨论了描述肠系膜侧支血管术语的正确用法。
我们查阅了历史文献，以讨论迂曲肠系膜动脉的手术意义。
尽管解剖学家和外科医生对其进行了长期研究，但对于肠系膜侧支血管的数量和正确描述术语仍存在混淆。
应摒弃含义模糊的历史术语“里罗兰弓”，采用更精确的术语“肠系膜迂曲动脉”。鉴于肠系膜迂曲动脉在提供肠系膜侧支循环方面的关键作用，在所有手术操作中，包括癌症切除术，都应常规保留该动脉。然而，对于无症状患者无需进一步评估。
