Endovascular repair of a celiac trunk aneurysm with a new multilayer stent

Abstract

Operative treatment of celiac trunk aneurysms has traditionally involved open repair using simple ligation, interposition graft, resection, and direct repair or antegrade bypass from the aorta; recently, endovascular techniques have been proposed in selected cases. We report a 60-year-old man presenting with a celiac trunk aneurysm that we treated with a new multilayer stent with the aim of preserving the parent vessels arising from the aneurysm. Computed tomography angiography at the 12-month follow-up visit confirmed the patency of the stents, the complete thrombosis of the sac without impairment of the main branches, and the regular perfusion of the liver and spleen.

Flow-diverting stents for the treatment of arterial aneurysms

“…[6][7][8][9] Two were included in the analysis. 7,9 Of 14 articles that we considered, 12 reported the use of FDSs in arterial aneurysms (Table I), 1,7,[9][10][11][12][13][14][15][16][17][18] one in thoracoabdominal dissection, 19 and one in carotid blowout syndrome. 20 The full texts of these articles were retrieved and reviewed.…”

Successfully-treated asymptomatic celiac artery aneurysm: A case report

“…Endovascular techniques, including stent implantation and embolization of aneurysms are feasible in the setting of advanced age and underlying diseases; while surgical intervention is a safe and effective method in selected cases [9], [10]. In our patient, endovascular treatment was considered unsuitable because the patient just recovered from bacteremia and the possibility of an infective aneurysm could not be excluded.…”

Hemodynamics study of a multilayer stent for the treatment of aneurysms

“…The multilayer structure has the effects of reducing and slowing the power of the vortices. The slowing of vortices and their alignment can create a filling that induces thrombosis [2]. …”

“…MS is used to the treatment of visceral artery aneurysms (VAA) originally; it isolates aneurysm effectively and guarantees the supply of blood to the branches. Then MS is gradually used in the treatment of thoraco-abdominal aortic aneurysms (TAAA) in the complex and important branches [2, 3]. …”

“…Polydorou et al [5] reported that 9 patients with MS got 100% technical successes between December 2006 and November 2009; Fossaceca et al [6] followed-up six patients who were treated by MSs for peripheral artery aneurysms from September 2010 to May 2011. Totally 12 stents were used, technical successes were achieved by 100%; Giampaolo et al [2] reported that a 60-year-old man presenting a celiac trunk aneurysm refused open surgical repair and then was treated with a MS to reduce the strength of vortex and induce thrombosis, after 12 month it confirmed that the thrombosis was formed in the sac without impairment of the main branches. Ferrero et al [3, 7] analyzed two males who had hepatic artery aneurysm were treated with MS, it showed the thrombosis of the aneurysmal sac and patency of the branches of hepatic artery by computed tomography (CT) scan in a 1 year follow-up.…”
