Síndrome da artéria mesentérica superior (AMS) é um transtorno muito raro, com risco de vida, caracterizada por uma compressão da terceira porção do duodeno pela aorta abdominal (AA) e pela artéria mesentérica superior sobreposta. A síndrome é tipicamente causada por um ângulo de 6°-25° entre AA e AMS._x000D_ Este termo inclui pacientes com a forma congênita crônica da síndrome da AMS, predominantemente com uma história longa ou mesmo vitalícia de queixas abdominais com exacerbações intermitentes dependendo do grau de compressão duodenal. Fatores de risco incluem características anatômicas tais como: constituição astênica do corpo, uma inserção excepcionalmente alta do duodeno no ligamento de Treiz, uma origem particularmente baixa da AMS ou má rotação intestinal em torno de um eixo formado pela AMS. | |||||||||||||||

Superior mesenteric artery (SMA) syndrome is a very rare, life-threatening disorder characterised by a compression of the third portion of the duodenum by the abdominal aorta and the overlaying superior mesenteric artery.

This contains patients with the chronic, congenital form of SMA syndrome, predominantly have a lengthy or even lifelong history of abdominal complaints with intermittent exacerbations depending on the degree of duodenal compression.

Superior mesenteric artery (SMA) syndrome is a very rare, life-threatening disorder characterised by a compression of the third portion of the duodenum by the abdominal aorta and the overlaying superior mesenteric artery. The syndrome is typically caused by an angle of 6°-25° between the AA and the SMA. This contains patients with the chronic, congenital form of SMA syndrome, predominantly have a lengthy or even lifelong history of abdominal complaints with intermittent exacerbations depending on the degree of duodenal compression. Risk factors include anatomic characteristics such as: asthenic body build, an unusually high insertion of the duodenum at the ligament of Treiz, a particularly low origin of the SMA, or intestinal malrotation around an axis formed by the SMA.
