Endovascular treatment of paravisceral mycotic aneurysm: Chimmeny endovascular sealing the end of de road

Open surgery is the elective treatment for mycotic aneurysms of the aorta. This surgery consists of resection of the aneurysm, debridement and revascularization with an in situ or extra-anatomic bypass. Even when surgery has been successful, the morbimortality is raised and the endovascular treatment has become an alternative for specific patients. When mycotic aneurysms involved the visceral arteries, more complex techniques are necessary such as fenestrated endovascular aortic repair or chimmeny endovascular aortic repair and the most frequent complications of this are endoleaks and oclussion the visceral arteries. We present a case of a pacient with a paravisceral abdominal mycotic aneurysms that was result with 2 chimney technique(in the right renal and superior mesenteric arteries) and a single Nellix EVAS(Endologix, Irvine, Calif) of 12 cm long without evidence of endoleaks in the follow-up.

Nonclassical Cause of Obstructive Jaundice: A Case Report of Multiple Visceral Arterial Aneurysms in a Young Patient

Multiple visceral artery aneurysms are relatively rare;the rarest are superior mesenteric artery and gastroduodenal artery aneurysms. The clinical presentation depends on the size and site of the aneurysm. We report the case of a 33-year-old man with recurrent episodes of obstructive jaundice and weight loss. Computed tomography with contrast revealed scattered hepatic arterial aneurysms with two other aneurysms along the course of the left gastro-duodenal and superior mesenteric artery. Investigations to determine the etiology were negative, but the patient had a history of smoking and substance abuse. Angiography revealed an occluded feeding artery. The patient developed multiorgan failure, leading to cardiac arrest and died. Diagnosing multiple visceral artery aneurysms needs a high index of suspicion;early diagnosis enables early intervention, which can reduce the high mortality of this condition.
