A 74-year-old patient presented with recurrent aneurysms in the infrarenal abdominal aorta and right common iliac artery 6 years after endovascular aortic repair using endografts in the same location. The patient underwent an aorto-bi-iliac replacement with removal of the stent graft. Two holes measuring 2 mm each were found in the removed graft, and they appeared to have been caused by wear from continuous friction between the endograft and the aortic wall.

INTRODUCTION: Neck enlargement is well described in patients treated with self-expandable endografts for abdominal aortic aneurysms. Double endografting (ie, overlapping of stent grafts) occurs in patients with proximal cuffs or bifurcated to monoiliacal configuration conversions. When the aortic neck of patients receives 2 suprarenal fixation endografts, it may behave differently in terms of radial force and interaction of additional suprarenal stents extending to the visceral aorta...

BACKGROUND: Previous studies comparing endografts with suprarenal and infrarenal fixation for endovascular abdominal aortic aneurysm repair (EVAR) have found conflicting results and did not account for differences in patient selection. This study aims to evaluate the differences in outcomes among surgeons who routinely use either suprarenal or infrarenal fixation, as well as all surgeons in the Vascular Study Group of New England (VSGNE). METHODS: All patients undergoing EVAR in the VSGNE from 2003 to 2014 were identified...

AIM: Bilateral limb occlusion after endovascular aortic repair (EVAR) is relatively uncommon. The aim of this study was to investigate the incidence of bilateral endograft limb occlusion after EVAR and identify potential anatomical predictive factors of occurrence. MATERIALS-METHODS: A total of 579 patients underwent elective EVAR for abdominal aortic aneurysm (AAA) between January 2010 and December 2015. All patients presenting with unilateral and bilateral occlusion were prospectively analyzed...

PURPOSE: The in situ fenestration of a standard endograft is currently limited by difficulties in targeting the fenestration site under fluoroscopic control and by the lack of a safe method to perforate the graft. Evidence in the literature suggests the use of a 3 D electromagnetic navigator to accurately guide the endovascular instruments to the target and a laser to selectively perforate the graft. The aim of this work is to provide design guidelines to develop a sensorized catheter to guide the laser tool to the fenestration site and conduct preliminary testing of the feasibility of the proposed solution...

BACKGROUND: Endovascular therapy has been increasingly used for critically injured adults. However, little is known about the epidemiology and outcomes of endovascularly managed arterial injuries in children. We therefore aimed to evaluate recent trends in the endovascular management of pediatric arterial injuries and its association with early survival. METHODS: An 8-year analysis of the National Trauma Databank (2007-2014) was performed to extract all pediatric trauma patients (aged ≤16 years) with arterial injuries...

PURPOSE: To describe the technical aspects of a thoracoabdominal aortic aneurysm (TAAA) repair using a patient-specific fenestrated-branched stent-graft. TECHNIQUE: The technique is demonstrated in a 69-year-old man with a 6.2-cm asymptomatic type III TAAA. A patient-specific fenestrated-branched stent-graft was designed with 2 down-going directional branches for the celiac and superior mesenteric arteries and 2 reinforced fenestrations for the renal arteries. The procedure was performed under general anesthesia and included sequential stenting of the celiac, superior mesenteric, and bilateral renal arteries...

PURPOSE: To demonstrate the successful treatment of an ascending aortic tuberculous pseudoaneurysm using endografts through the transapical body floss wiring technique with rapid ventricular pacing support. CASE REPORT: A 77-year-old woman with a nonhealing anteromedial chest wound presented with sudden hypotension and hemoptysis. A computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of the ascending aorta with sternal erosion near the wound. Conventional open repair was not preferred because of possible contamination of the interposition graft and difficult sternum closure...

PURPOSE: We report the case of a thoracic endograft used to achieve exclusion of a ruptured proximal paranastomotic abdominal aortic aneurysm (PAAA) as a consequence of aortic ballooning. CASE REPORT: A type I proximal endoleak was evidenced following endovascular repair of a PAAA with an aortic cuff. The leak was treated with ballooning, which caused distal aortic rupture. A thoracic endograft was deployed inside the cuff, achieving complete exclusion. At 1 year, there are no signs of migration or endoleak with complete PAAA thrombosis, according to computed tomographic angiography...

Iliac arterial disease, unfavorable anatomy, and prior stenting all pose challenges to access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR). Iliac access injury during T/EVAR may lead to rupture, dissection, thrombosis, or distal ischemia. Some have advocated iliac stent prior to T/EVAR in patients with suboptimal iliac access. The rate of complication and iliac stent migration during subsequent T/EVAR is undocumented. This case report describes a unique instance of self expanding iliac stent migration during TEVAR which pinched the thoracic aortic endograft causing functional aortic coarctation...

INTRODUCTION: Acute occlusion of the visceral arteries is a threatening complication following branched endovascular aortic repair. Its prompt diagnosis and treatment are mandatory to restore renal function. Several techniques have been used to manage this complication. We present rheolytic thrombectomy as an effective treatment in two patients who developed this condition. PATIENTS AND METHODS: We report two clinical cases of patients, previously treated with implantation of an off-the-shelf thoracoabdominal aortic endograft, with acute bilateral occlusion of the renal arteries...

We describe a rare case of acute type B dissection causing collapse of a previously placed infrarenal stent-graft, resulting in acute limb ischemia due to left iliac limb thrombosis in a 59-year-old male. The patient presented with acute back and abdominal discomfort radiating to his back, bilateral buttock stabbing discomfort, and left> right thigh and calf rest pain. CTA showed a spiral type B dissection with collapse of the proximal portion of the EVAR device and left limb occlusion. Urgent treatment with TEVAR distal to the left subclavian covered the entry tear and redirected the majority of the flow to the true lumen leading to near immediate expansion of the proximal portion of the EVAR device...

BACKGROUND: large gutters after chimney procedures are one of the main causes of type I endoleak (EL-I). This study aims to evaluate a new tailored planning named "Over-SIRIX", based on Osirix Imaging Software, to choose the correct main graft oversizing in order to minimize EL-I incidence. METHODS: from 2008 to 2015, 34 patients were treated with parallel grafts for aortic arch diseases at our institution. The study included 22 patients with single stent and antegrade flow configuration; they were divided in two groups (PRE and POST "Over-SIRIX")...

INTRODUCTION: Proximal aortic dilation following open and endovascular aortic repair (EVAR) is a well-known phenomenon. If severe enough it may lead to late onset of type Ia endoleak that jeopardise the proximal seal. CASE REPORT: We report the case of a patient previously treated by EVAR for an infrarenal aneurysm who developed a type Ia endoleak after proximal aortic dilation. His aneurysms enlarged to 10 cm mandating a rapid repair without the delay for a custom-made device...

The coexistence of Abdominal Aortic Aneurysm (AAA) and Congenital Pelvic Kidney (CPK) is infrequent. Various treatment modalities have been reported in literature for treatment of the above condition. We report a complete endovascular modality for the treatment of this association, especially for high-risk patients. Only one such treatment has been reported before. Compared to this previously reported case, we would like to share our experience with additional prototype testing, prior to surgery which provided us with more detailed information about the planning and deployment of the branched endograft...

The endovascular realm has steadily increased its footing in the treatment of the aorta and all of its territories since the foundational case in 1990 by Parodi. The aortic arch, however, continues to be one of the last bastions for treatment via open surgery, which remains the gold standard. Significant comorbidity and prior cardiac surgery prevent open surgery from being the only preferred option, allowing novel endovascular procedures to be considered. Since 1999, more advanced endovascular systems have been created by companies such as Cook Medical, Bolton Medical, Medtronic, Endospan, Gore Medical, and, recently, Kawasumi...
