The natural history is progressive, caused by atherosclerosis progression in a polymorbidity and aging society. Due to collateralization, diffuse stenotic lesions can remain asymptomatic for a long time and usually manifests when an acute medical or surgical event occurs. In those cases, the clinical suspicion is crucial to reach the diagnosis promptly, allowing to preserve the patients&#8217; quality of life and, above all, the patients&#8217; life.  Clinical case 1:  A 48-year-old woman with a history of smoking goes to the emergency department for hypogastric abdominal pain, nausea, and vomiting. A study was performed by computed tomography angiography (CTA) that demonstrated occlusion of the superior mesenteric artery (SMA) and significant stenosis of the celiac trunk associated with thickening of small bowel suggestive of ischemia. A thrombectomy of the superior mesenteric artery and retrograde stenting of the artery ostium was performed, followed by extensive enterectomy on 24-hour laparotomy. After hospital discharge, the patient had new abdominal complaints, and stent occlusion was documented in the SMA. She underwent an iliohepatic bypass with good results.  Clinical case 2:  A 76-year-old man previously submitted to a right axillofemoral and femoropopliteal sequential bypass to treat chronic limb-threatening ischemia (CLTI), went to the emergency department with complaints of abdominal pain, vomiting, and constipation. The diagnosis of a subocclusive intestinal syndrome was made, having performed a computed tomography (CT) scan where it was observed the Ileum adhered to the cecum, which was thickened; the celiac trunk and SMA had subocclusive stenosis. The patient underwent primary celiac trunk stenting with a balloon-expandable stent. After celiac artery revascularization, a right colectomy was performed with two segmental enterectomies.  Conclusion:  Mesenteric ischemia is a severe condition that is often underdiagnosed due to the lack of awareness of most physicians and nonspecific symptoms. The vascular intervention aims to prevent intestinal necrosis, which can lead to the patient&#8217;s death. Timely diagnosis is therefore essential, and revascularization must be performed before or at the same time as intestinal surgery. The close collaboration between the general and vascular surgery teams is essential to the success of these cases.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo  Introdução:  A isquemia mesentérica crónica como resultado de uma disfunção do fluxo sanguíneo nos órgãos viscerais é caracterizada por um curso clínico insidioso e, portanto, é frequentemente uma doença subestimada e subtratada. A história natural é progressiva, causada pelo desenvolvimento da aterosclerose numa população envelhecida e com múltiplas comorbilidades. Devido à extensa colateralidade, as lesões estenóticas difusas podem permanecer assintomáticas por muito tempo e manifestarem-se apenas quando ocorre um evento clínico ou cirúrgico agudo. Nestes casos, a suspeita clínica é fundamental para se chegar a um diagnóstico atempado de forma a preservar a qualidade de vida do doente e, principalmente, assegurar a sua sobrevida.  Caso-clínico 1:  Mulher de 48 anos de idade com antecedentes de tabagismo recorre ao serviço de urgência por dor abdominal hipogástrica, náuseas e vómitos. Foi realizado estudo por angio-tomografia computorizada (ATC) que demonstrou oclusão da artéria mesentérica superior, e estenose significativa do tronco celíaco e espessamento de ansas do intestino delgado sugestivo de sofrimento isquémico. Foi realizado uma trombectomia da artéria mesentérica superior (AMS) e stenting retrógrado do seu ostio seguido posteriormente de enterectomia extensa na laparotomia das 24 horas. Após alta hospitalar, a doente apresentou novo quadro abdominal tendo sido documentada a oclusão do stent na AMS. Foi submetida a um bypass ílio-hepático com bom resultado.  Caso-clínico 2:  Homem de 76 anos de idade previamente submetido a um bypass sequencial axilo-femoral e femoropopliteo direitos para tratamento de isquemia crónica com ameaça de membro. O doente recorreu ao serviço de urgência com dor abdominal, vómitos e obstipação. Foi realizado o diagnóstico de um quadro suboclusivo tendo realizado estudo por tomografia computorizada (TC) onde se observou aderência de ansas do íleon ao cego que se encontrava espessado; o tronco celíaco e AMS apresentavam estenoses suboclusivas. O doente foi submetido a um stenting primário do tronco celíaco com stent expansível em balão. Após a revascularização celíaca foi realizada uma colectomia direita com duas enterectomias segmentares.  Conclusão:  A isquemia mesentérica é uma patologia grave muitas vezes subdiagnosticada por falta de atenção para a doença por parte da generalidade dos médicos bem como pelos sintomas inespecíficos. A intervenção vascular visa impedir a necrose intestinal que pode mesmo levar à morte do doente. O diagnóstico atempado é assim fundamental e a revascularização deve ser realizada antes ou no mesmo tempo da cirurgia intestinal. A estreita colaboração entre as equipas de cirurgia geral e vascular é de essencial importância para o sucesso destes casos.]]></p></abstract>
