Vasculitis del tronco celíaco como presentación de arteritis de Takayasu / Vasculitis of the celiac artery as a presentation of Takayasu's arteritis

La arteritis de Takayasu es una vasculitis idiopática y granulomatosa crónica que se manifiesta en forma de panaortitis, de etiología desconocida, aunque se postula un origen autoinmune. Es progresiva y genera, tanto en adultos como en niños, estenosis segmentaria, oclusión, dilatación y/o aneurismas. La vasculitis aislada gastrointestinal sin afectación sistémica es rara. Este caso lleva a tener en cuenta la manifestación abdominal atípica de la arteritis de Takayasu en el diagnóstico diferencial de un síntoma frecuente, como la epigastralgia, y a destacar el rol que ocupan en la actualidad los métodos de imágenes no invasivos para su diagnóstico.

Takayasu arteritis is an idiopathic and chronic granulomatous vasculitis manifested in the form of panaortitis, of unknown etiology, even though an autoimmune origin is postulated. It is progressive and generates, in adults and children, segmental stenosis, occlusion, dilation and / or aneurysms. Isolated gastrointestinal vasculitis without systemic involvement is rare. This case leads us to take into account the atypical abdominal manifestation of Takayasu arteritis in the differential diagnosis of a frequent symptom, such as epigastralgia, and to highlight the role currently played by non-invasive imaging methods for its diagnosis.

Prevalência da estenose aterosclerótica do tronco celíaco e da artéria mesentérica superior na arteriopatia oclusiva dos membros inferiores / Prevalence of atherosclerotic stenosis of celiac trunk and superior mesenteric artery in occlusive arteriopathy of lower limbs

A eventual relação entre a aterosclerose das artérias dos membros inferiores com a aterosclerose das artérias intestinais foi pouco estudada. Objetivo: Avaliar pela ecografia vascular (Doppler) presença de lesões com estenose 70 por cento na artéria mesentérica superior e/ou tronco celíaco em doentes com arteriopatia obstrutiva crônica dos membros inferiores. Método: Foram estudados dois grupos, cada um com 60 doentes (40 homens e 20 mulheres). O grupo-caso foi composto por doentes com arteriopatia obstrutiva crônica dos membros inferiores, claudicação intermitente limitante ou dor de repouso e/ou lesões tróficas de extremidade, sem queixas gastrintestinais...

Tratamiento quirúrgico de la isquemia mesentérica crónica: Caso clínico / Surgical treatment of chronic mesenteric ischemia: Report of one case

Although the classic therapy for chronic mesenteric ischemia is surgical revascularization, endovascular therapy is a new therapeutic option. We report a 55 year-old female, with a 2 years history of post prandial abdominal pain, diarrhoea, and weight loss, with occlusion of both mesenteric arteries and critical stenosis of the celiac artery. The initial treatment consisted in angioplasty and celiac artery stent placement in two occasions, with a brief symptomatic relief. Finally, a visceral artery bypass was performed, with good post operative outcome and complete symptomatic resolution at one year follow up. In our opinion endovascular therapy is a good therapeutic option for chronic mesenteric ischemia in high surgical risk patients, specially when dealing with stenotic injuries. It may also be a complement for patients who need to recover their nutritional status prior to revascularization surgery. On the other hand, due to the long term patency and symptomatic relief, surgical treatment is a good option in low risk patients.
