Endurant stent graft

BACKGROUND: The aim of this study was to evaluate the anatomical feasibility of current available fenestrated endografts (FEVAR) and on-label chimney technique (EnChEVAR) in patients with complex abdominal aortic aneurysms (C-AAA). METHODS: Feasibility of EnChEVAR (Endurant II/IIS CE-marked [Medtronic]) and 4 types of FEVAR (Zenith Fenestrated CE-marked, Zenith Fenestrated Low-Profile [LP] custom-made device [CMD] [Cook Medical], Fenestrated Anaconda LoPro90 CMD, Fenestrated Treo CMD [Terumo Aortic]) was assessed according to the manufacturer's instructions for use...

The procollagen-lysine, 2-oxoglutarate 5-dioxygenase 1 (PLOD1) gene may affect arterial integrity through enzymatic roles and the modulation of vascular smooth muscle cells. This report presents a complicated vascular case in an eight-year-old male child with Ehlers-Danlos syndrome Type VI. The patient was diagnosed with a ruptured pseudoaneurysm of the infrarenal abdominal aorta. Endovascular treatment was performed using a covered self-expandable endograft (10 × 59 mm; Medtronic Endurant II)...

PURPOSE: To describe the endovascular treatment of a symptomatic juxtarenal abdominal aortic aneurysm (JAAA) using a combination of endoanchors (Heli-FX EndoAnchor, Medtronic, Minneapolis, Minnesota) and a physician-modified single-fenestrated endograft. TECHNIQUE: An 85 year-old patient unfit for open aortic repair presented for a symptomatic JAAA, characterized by an infrarenal neck with 0.6 cm in length and 23 mm in diameter. A 28 mm-diameter Endurant aortic cuff (Medtronic, Minneapolis, Minnesota) was modified with a single fenestration for the left renal artery (LRA) and diameter-reducing tie, then re-sheathed and deployed...

OBJECTIVE: Hostile aortic neck anatomies such as proximal short necks are known to put patients at an increased risk for type IA endoleaks, migration, and need for reinterventions. The Heli-FX EndoAnchor System was designed to improve seal of aortic stent grafts. Endosuture aneurysm repair (ESAR) using EndoAnchors with the Endurant stent graft has been shown to be safe and effective for the treatment of patients with short necks through one year. This study reports the 5-year patient outcomes of the Aneurysm Treatment using the Heli-FX EndoAnchor System Global Registry (ANCHOR) short neck regulatory cohort...

OBJECTIVE: Significant sac regression during early surveillance has been shown to best predict reintervention-free long-term surveillance after endovascular aneurysm repair (EVAR). Furthermore, a persistent endoleak has been related to a worse outcome. Individualized surveillance algorithms based on these findings have been suggested. There are no studies comparing the performance of different stent grafts regarding sac regression, the presence of type II endoleaks, and their possible implications for individualized surveillance...

OBJECTIVE: To investigate the occurrence of limb graft occlusion (LGO) and intra-prosthetic thrombus (IPT) formation in Zenith Alpha and Endurant II stent graft limbs. METHODS: A single centre retrospective study was conducted on patients treated with the Zenith Alpha and Endurant II stent grafts between 2017 and 2019. All post-operative computed tomography angiography images were re-investigated for thrombus formation. Demographic, aneurysm, and stent graft data were collected and compared...

PURPOSE: We describe the feasibility and early results of a novel endovascular approach with a surgeon-modified fenestrated iliac stent graft to preserve pelvic perfusion in patients with iliac aneurysms not suitable for iliac branch devices (IBDs). TECHNIQUE: Seven high-risk patients, median age 76 years (range 63-83), with a complex aortoiliac anatomy with contraindications for commercially available IBDs were treated with a novel surgeon-modified fenestrated iliac stent graft between August 2020 and November 2021...

OBJECTIVE: To evaluate in vitro the performance of in vivo published covered or bare-metal chimney stents (ChSs) in combination with Endurant II abdominal endograft (Medtronic) as the only CE-approved main graft (MG) in the treatment of juxtarenal abdominal aortic aneurysms with the chimney endovascular aneurysm repair (chEVAR) technique. METHODS: Benchtop experimental study. A silicon flow model with adjustable physiological simulating conditions and patient-based anatomy was used to test nine different MG-ChS combinations: Advanta V12 (Getinge); BeGraft+ (Bentley); VBX (Gore & Associates Inc...

INTRODUCTION: Endoleaks are a common complication following endovascular aneurysm repair, yet type IIIb are rare, especially with newer devices, and associated with high morbidity due to repressurisation of the sac. As endografts are used in patients with longer life expectancy, late type IIIb endoleaks are to be expected. This is a report of a giant common iliac aneurysm resulting from a misdiagnosed type IIIb endoleak. REPORT: An 85 year old man with history of right common iliac artery aneurysm, treated in 2003 with an EXCLUDER AAA Endoprosthesis (WL Gore, Flagstaff, AZ, USA) with iliac limb extension into the external iliac artery, presented at the emergency department with abdominal pain, hypotension, and syncope...

INTRODUCTION: Current bifurcated aortic endografts are unsuitable for patients with a narrow distal aorta except AFX2, which is unavailable in South Korea. An iliac branch device (IBD) was introduced to exclude iliac aneurysms while preserving the pelvic circulation. With advancements in endovascular techniques, various attempts for outside instructions for use have been reported to be practicable in certain patients. PATIENT CONCERNS: A 58-year-old man was referred to our emergency room with an incidentally found left common iliac artery aneurysm (CIAA) in a general checkup...

PURPOSE: Iliac branch devices (IBD) are widely used to treat aortoiliac aneurysms with an unfit distal landing zone for standard endovascular aneurysm repair (EVAR). The aim of this retrospective study was to examine the treatment of aortoiliac aneurysms with the combination of the Endurant II(s) stent graft system (Medtronic® ) and the E-liac stent graft (Artivion® ). MATERIALS AND METHODS: Data of all patients who underwent an EVAR combined with unilateral or bilateral IBD between January 2015 and January 2020 were analyzed...

OBJECTIVES: Patients with Marfan syndrome are usually not suitable for endovascular repair of the thoracoabdominal aorta. This study was designed to analyze our center's experience with open surgical thoracoabdominal aortic replacement in Marfan patients. METHODS: This was a retrospective study with prospective follow-up. Between January 1995 and September 2021, a total of 648 patients underwent thoracoabdominal aortic replacement at our center. Of these, 60 had Marfan syndrome and were included in this study...

Recently, endovascular aortic aneurysm repair (EVAR) is the most common surgery for abdominal aortic aneurysm (AAA). However, iliac limb complications of EVAR often cause problems in patients with high iliac tortuosity. There is no difference of rate of iliac limb complication among EVAR devices, such as Excluder, Endurant, and Zenith in high iliac tortuosity. But there has been not reported about AFX. We studied AFX iliac extension as it is the only stent graft with an endoskeletal framework. This study aimed to evaluate the AFX iliac extension patency in a case in vitro and to use it in seven cases of AAA with high iliac tortuosity...

The use of Heli-FX EndoAnchors (Medtronic CardioVascular, Santa Rosa, CA) with the Endurant II stent graft (Medtronic CardioVascular) has been approved by the Food and Drug Administration for juxtarenal abdominal aortic aneurysms with neck lengths ≤4 mm. The use of this technique of endosuture aneurysm repair has not been previously described in the setting of rupture. We have presented two cases of successful endosuture aneurysm repair of ruptured juxtarenal AAAs.

BACKGROUND: Hostile anatomy, especially severely angulated neck and tortuous iliac arteries, has always been a conundrum in endovascular aneurysm repair (EVAR). Crossed limb (CL) graft, also called the "ballerina technique," has been utilized to address this problem by facilitating gate cannulation. In terms of short and long-term outcomes, correlated studies have made inconsistent conclusions and this issue remains controversial. Based on a previous cohort study conducted in our center, we aim to prospectively compare the safety and efficacy between CL and standard limb (SL) configuration in patients receiving EVAR...

Background: Endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs) has emerged as a better alternative to conventional open surgery for AAAs. The purpose of the review is to define the improvement in the clinical management of the patient with hostile neck AAAs due to the introduction of new endografts while giving a thorough description of their instructions for use (IFUs), main characteristics and part sizing, reporting their outcomes from clinical studies and categorizing their usability...

OBJECTIVE: The aim of the Endurant for Challenging Anatomy: Global Experience (EAGLE) registry is to prospectively evaluate the technical and clinical success rate of a stent graft used in patients with challenging neck anatomy outside IFU, but within objective anatomical limits. DESIGN: Prospective, international, multicentre, observational study. METHODS: From 1 February 2012 to 1 September 2017, patients with an abdominal aortic aneurysm with a challenging infrarenal neck that were deemed suitable for EVAR were prospectively included at 23 European centres...

The objective of this article is to describe a patient with hemorrhagic shock due to type 3 postendovascular aortic repair rupture successfully treated with the endurant II stent graft via a primary endovascular approach with a rapid response protocol. A 65-year-old male patient who underwent endovascular aortic repair 3 years ago was admitted to the emergency department with severe abdominal pain and hemorrhagic shock. The patient was rapidly taken to the angiography laboratory, and aortography demonstrated distal aortic graft rupture and extravasation of contrast media...

BACKGROUND: The purpose of this study is to elucidate the role of the AFX2 platform in the endovascular treatment of aortic pathology. METHODS: All procedures by a single surgeon resulting in implantation of a bifurcated unibody stent graft were reviewed retrospectively. Indications for selection of the AFX2 endograft in each case were evaluated. Aortic anatomy was determined via review of pre-operative computed tomography (CT) scans. Cumulative event probabilities for endoleak, reintervention, and mortality were estimated...
