Chimney Stent-Graft Repair for Concurrent Inferior Mesenteric Artery Aneurysm and Infrarenal Abdominal Aortic Aneurysm: Case Report

A Case of Thrombosed Inferior Mesenteric Artery Aneurysm Concomitant with Abdominal Aortic Aneurysm Treated by Endovascular Aneurysm Repair

“…The exact rate of the concur- rence of AAA and IMAA has not yet been clarified, but some describes it to be very rare. 3) The IMAA in our case was not typical as seen in previous reports. 1,[3][4][5][6][7] Regardless of whether the aneurysm is fusiform or saccular, most of the splanchnic artery aneurysms have the neck and end.…”

Total Endovascular Therapy of Abdominal Aortic Aneurysm, Peripheral Artery Disease, and Chronic Mesenteric Ischemia: A Challenging Case

“…Indications of preservation could be bilateral occlusion of hypogastric artery or occlusion of SMA or of the celiac trunk. Other indications could be synchronous AAA and IMA aneurysm or a previous colon procedure where the collateral network is probably interrupted [3,4]. However, all these indications remain relative and are not well documented.…”

“…For example, this technique was performed on a patient diagnosed with concomitant AAA and IMA aneurysm. The chimney technique could also be preferred in patients diagnosed with AAA and bilateral occlusion of the hypogastric artery [2–4,7]. Parallel grafts have proved to be feasible and safe and the authors agree with Rancic’s opinion [8] that the chimney technique should not be considered as a bailout technique but as a planned pre-operative procedure to maintain the perfusion of an artery [5,6].…”

“…Current recommendations suggest evaluation and treatment of symptomatic superior mesenteric artery (SMA) stenosis before EVAR or OSR and preservation of at least one internal iliac artery in order to prevent postoperative bowel ischemia following AAA repair [2]. Moreover, while chimney technique is usually utilized for juxtarenal aneurysms (to increase the proximal landing zone) or in aortic arch pathologies, it has been also described for inferior mesenteric artery (IMA) preservation in small case series/case reports [3,4]. We herein present the total endovascular treatment of a high-risk patient diagnosed with AAA, symptomatic AIOD, and chronic mesenteric ischemia.…”

Short- and long-term follow-up after transarterial embolization of a giant inferior mesenteric artery aneurysm

“…IMAAs are extremely rare. Until 2018, only 65 true IMAA cases had been published in the English-language medical literature; patients ranged in age from 9 to 84 years, and 51 men and 14 women have been affected 4, 7, 8, 9, 10, 11, 12, 13. However, no reported case presented with the dimensions described here.…”
