Endurant stent graft

BACKGROUND: Early type IIIb endoleak is a very rare complication of endovascular aneurysm repair (EVAR). CASE PRESENTATION: An 87-year-old man was diagnosed with infrarenal abdominal aortic aneurysm. The patient underwent EVAR using the Endurant stent graft. Postoperative color duplex ultrasound revealed a regular row of pulsatile blood flow from the main body and left leg. The blood flow appeared to be bleeding from the stent suture lines because of its regularity...

PURPOSE: To compare the long-term outcomes of the most widely used third-generation stent grafts, the Endurant and Excluder stent grafts, in Japanese patients using a multicenter registry. MATERIALS AND METHODS: A retrospective analysis of endovascular aneurysm repairs for abdominal aortic and iliac artery aneurysms using either the Endurant or the Excluder stent grafts from January 2012 to July 2019 at 10 Japanese hospitals was performed. RESULTS: A total of 332 and 378 repairs using the Endurant and Excluder stent grafts, respectively, were analyzed...

BACKGROUND: Recent studies on the Endurant™ endografts mainly compared outcomes of the bimodular stent-graft to other manufacturer's endografts or reported results for cases outside manufacturer's instructions for use (IFU), while data on the experience of standard endovascular aortic repair (EVAR) of infrarenal abdominal aortic aneurysms (AAA) inside manufacturer's IFU comparing the bi- with the trimodular device is limited. METHODS: Inclusion criteria were: 1) infrarenal aneurysms (>50 mm diameter) treated by EndurantTM II (END II) or EndurantTM IIs (END IIs) stent-graft inside manufacturer's IFU; 2) available CTA with 1 mm reconstruction of the entire aorta prior to intervention...

BACKGROUND: Post implantation syndrome (PIS) represents an acute phase systemic inflammatory response following endovascular aortic aneurysm repair (EVAR). Our objective was to investigate the risk factors associated with the manifestation and severity of PIS with various available stent-grafts. MATERIALS AND METHODS: We performed a retrospective analysis of prospectively collected data covering the period 2016 - 2020. 191 patients were included. Body temperature was recorded regularly and blood sample was obtained daily...

OBJECTIVE: To identify and analyze the published in vitro benchtop experiments for the assessment of endovascular techniques used for the treatment of juxtarenal abdominal aortic aneurysms (jAAAs). DATA SOURCES: Scopus, PubMed, and Web of Science. REVIEW METHODS: A systematic literature search was carried out throughout March 2021 following PRISMA guidelines. Two investigators independently performed title and abstract screening to reveal all benchtop testing evaluating the endovascular treatment of jAAA...

Thoracic endovascular aortic repair is widely used for type B aortic dissection. However, there is no favorable stent-graft for type A aortic dissection. A significant limitation for device development is the lack of an experimental model for type A aortic dissection. We developed a novel three-dimensional biomodel of type A aortic dissection for endovascular interventions. Based on Digital Imaging and Communication in Medicine data from the computed tomography image of a patient with a type A aortic dissection, a three-dimensional biomodel with a true lumen, a false lumen, and an entry tear located at the ascending aorta was created using laser stereolithography and subsequent vacuum casting...

BACKGROUND: Endovascular treatment of complex common iliac artery (CIA) and internal iliac artery (IIA) aneurysms using iliac branch endoprostheses (IBE) has proven safe and effective. Instructions for use (IFU) require deployment of current IBE technology with the corresponding manufacturer's modular bifurcated aortic endograft. Concomitant aortoiliac occlusive disease, inadequate renal artery-iliac bifurcation length, and unfavorable aortic anatomy preclude on-label IBE deployment. This study aimed to evaluate the technical feasibility and safety of Alternative Endograft Aortoiliac Reconstruction (AEGAR) for branched endovascular treatment of complex iliac artery aneurysms...

We report a case of combined types IIIb and Ia endoleak that developed 6 years after endovascular aneurysm repair (EVAR) with the Endurant II® endograft for abdominal aortic aneurysm (AAA). The patient presented with post-EVAR AAA rupture and underwent emergency open repair. We observed types IIIb and Ia endoleak and successfully performed felt banding to preserve the stent graft. Type IIIb endoleak with the Endurant® endograft is rare, and treatments have not been fully established. We summarized the case reports regarding type IIIb endoleak with the Endurant® endograft and mainly discussed the treatments...

Background Endovascular aneurysm repair (EVAR) has become the treatment modality of choice in patients with abdominal aortic aneurysms. This has resulted in endograft utilization within instructions for use (IFU) and in cases with proximal neck anatomy outside of IFU. Purpose To identify whether graft selection influences outcomes following EVAR outside of IFU. Methodology A retrospective analysis was conducted from previously published data for 636 patients, collated from the Endurant Stent Graft Natural Selection Global Post-Market Registry (ENGAGE) and the Global Registry for Endovascular Aortic Treatment (GREAT)...

INTRODUCTION: Delayed wound healing and ulceration in radiated tissue is a surgical challenge. Autologous fat grafting can reverse skin changes secondary to radiation such as fibrosis, scarring, contracture, and pain. Adipose-derived stem cells are thought to contribute to the regenerative properties of fat. OBJECTIVE: In this case report, the authors discuss the role of fat grafting as a means for effective wound healing in a patient with a chronic nonhealing radiation-induced skin wound...

Background Abdominal aortic aneurysms (AAA) are far more common in male than female gender, although they appear to have a more aggressive pathophysiology in females. Given the lower incidence of AAA in females, it has been difficult to assess the impact of graft selection for endovascular aortic aneurysm repair (EVAR) in this cohort. Purpose To identify whether graft selection influences outcomes following AAA endoluminal repair in female patients. Methodology A retrospective analysis of published data for 711 female patients was conducted, collating data from three cohorts - Endurant Stent Graft Natural Selection Global post-market registry (ENGAGE), Global Registry for Endovascular Aortic Treatment (GREAT) and U...

INTRODUCTION: Currently, there is a wide range of commercially available devices for endovascular aneurysm repair (EVAR) that differ in terms of both anatomical requirements and the technology and technique of deployment. AIM: To assess the applicability of currently commercially available devices for EVAR in the treatment of an asymptomatic abdominal aneurysm (AAA). MATERIAL AND METHODS: The study group included 100 patients with infrarenal AAA with a maximum diameter ≥ 50 mm, qualified for invasive treatment at the University Hospital in 2013-2014...

BACKGROUND: The bifurcated AFX (Endologix, Inc, Irvine, CA, USA) aortic stent-graft is the sole unibody endograft for the management of Abdominal Aortic Aneurysms (AAA). In order to improve the AFX central sealing and clinical efficacy in challenging cases, a replacement of the central chromium-cobaltium AFX extension with a Nitinol-based proximal aortic cuff has been suggested. Yet, comparative data regarding the hemodynamic performance of this design is missing. Aim of this study was to compare the displacement forces (DF) acting on the hybrid AFX-Endurant design, with the classic AFX and Endurant endografts, in angulated and non-angulated cases based on patient-specific Computational Fluid Dynamics (CFD) simulations...

BACKGROUND: Endovascular aneurysm repair (EVAR) has become the preferred treatment for infrarenal abdominal aortic aneurysms (AAA) over open surgical repair. The Endurant stent graft is widely used, and large registries report low rates of aneurysm-related mortality and reinterventions at midterm follow-up. Reports of long-term follow-up are limited. The aim of this study is to report our experiences and share our results, reintervention rate and mortality at long-term follow-up after using the Endurant stent graft...

OBJECTIVE: The Terumo Aortic (TA) Treo Device is an endograft with unique features that lends itself to fenestrated endovascular aneurysm repair (FEVAR), including low device profile, wide amplitude stent design, and increased inter-stent distance. We sought to describe our initial experience with this device for FEVAR to treat short neck and juxtarenal abdominal aortic aneurysms (JAAA). METHODS: As part of an ongoing physician sponsored investigational device exemption clinical trial (#NCT01538056), subjects were prospectively enrolled and underwent elective FEVAR using a variety of devices...

OBJECTIVE: The aim was to identify predictors of adequate pre-operative sizing and planning for chimney endovascular aortic repair (ChEVAR) in order to reduce the incidence of persistent type Ia endoleaks (IaELs) without influencing chimney graft (CG) patency. METHODS: Consecutive patients who underwent ChEVAR between January 2009 and December 2017 at a single centre were evaluated retrospectively. Included were patients treated with one device combination (Medtronic Endurant mated with Getinge Advanta V12/iCast) and placement of single or double CG...

Introduction Endograft (EG) infection after endovascular aneurysm repair (EVAR) represents one of the most serious complications. Although the incidence of EG is below 1%, it is often associated with high mortality and morbidity rates. The therapeutic options are limited and should be individualized based on patient's general condition and co-morbidities. Objectives Regarding a clinical case of EVAR EG infection, a review is made on the difficult management of these patients. Materials and Methods We report a 72-years old male patient with medical history of hypertension, chronic tobacco abuse and peripheral artery disease...

Primary aortic tumors after endovascular aortic repair are rarely reported in the literature. Here, we report an elderly male with abdominal aortic leiomyosarcomas (LMS) after an endovascular aneurysm repair in 2012 for a 5-cm symptomatic abdominal aortic aneurysm using an Endurant II aortic stent graft (Medtronic, Minneapolis, Minn). The autopsy confirmed the aortic LMS after the patient rapidly deteriorated and succumbed to death. The vascular LMS are rapidly progressive and diagnostically challenging malignant soft tissue tumors with poor prognosis, which necessitates a strong clinical suspicion and attentiveness to radiologic signs for prompt diagnosis...

OBJECTIVES: The Medtronic Endurant II stent graft has recently received Conformité Européenne (CE) approval for the use in chimney endovascular aortic repair (ChEVAR) for the treatment for juxtarenal aortic aneurysms. The aim of this study was to assess the percentage of patients treated by fenestrated endovascular repair who would have been alternatively suitable for the treatment by the CE approved Medtronic ChEVAR. METHODS: Preoperative computed tomography scans of 100 patients who underwent fenestrated endovascular aortic repair (FEVAR) between April 2013 and February 2017 were retrospectively assessed for the applicability of the ChEVAR technique according to the Medtronic instructions for use...

OBJECTIVE: Endovascular repair is the preferred method of treatment for infrarenal abdominal aortic aneurysms with numerous publications from multiple geographic regions showing excellent patient outcomes. Since the original ACE (Anevrysme de l'aorte abdominale: Chirurgie versus Endoprothese) randomised control trial, studies of French specific population have also contributed significantly to the body of evidence in support of endovascular abdominal aortic repair. METHODS: In the ENDURANT France registry, 180 patients were consecutively enrolled from 20 French centres starting in 2012...
