PURPOSE: To assess if the suitability of endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs) can be expanded by combining the Endurant stent-graft with the Heli-FX EndoAnchors. MATERIALS AND METHODS: Contrast-enhanced computed tomography (CT) scans of 90 patients (mean age 73.2±9 years; 87 men) with RAAA admitted between January 2014 and January 2018 in 2 tertiary care centers were analyzed in a 3-dimensional workstation. Anatomical features of the aneurysms according to the instructions for use (IFU) for the Endurant endograft were evaluated and expansion of treatment with Heli-FX EndoAnchors was assessed...

INTRODUCTION: Endovascular repair of infra-renal aortic aneurysm (EVAR) has become treatment of choice. However, individuals undergoing EVAR have a high re- intervention rate. The aim of this study is to evaluate the current endovascular treatment modalities of endoleak type Ia (ET Ia) treatment after EVAR and their outcome. EVIDENCE ACQUISITION: A systematic review and meta-analysis was performed. MEDLINE, EMBASE and Cochrane databases were searched with PRISMA methodology for studies reporting on endovascular treatment of ET Ia after EVAR...

OBJECTIVE: The Society for Vascular Surgery reporting standards for endovascular aneurysm repair (EVAR) consider the presence of a type I or type III endoleak a technical failure. However, the nature and implications of these endoleaks in fenestrated EVAR (FEVAR) are not well understood. METHODS: We performed a single-center retrospective review of 53 patients who underwent FEVAR with the Zenith Fenestrated AAA Endovascular Graft (Cook Medical, Bloomington, Ind) from 2013 to 2018...

Complications during follow-up - including loss of seal and graft migration with endoleakage - are the Achilles heel of endovascular abdominal and thoracic aneurysm repair (EVAR and TEVAR, respectively). At the level of the proximal and distal landing zones, the characteristics of aortic anatomy include length and shape, thrombus, calcification, kinking and progressive dilatation, and these may impact the long-term durability of endovascular repair. Endoanchors have been shown to mimic the stability of a hand sewn aortic anastomosis...

OBJECTIVE: Standard endovascular aneurysm repair (EVAR) is the most common treatment of abdominal aortic aneurysms (AAAs). EVAR has been increasingly used in patients with hostile neck features. This study investigated the outcomes of EVAR in patients with neck diameters ≥30 mm in the prospectively maintained Endurant Stent Graft Natural Selection Global Postmarket Registry (ENGAGE). METHODS: This is a retrospective study comparing patients with neck diameters ≥30 mm with patients with neck diameters <30 mm...

OBJECTIVE: This study sought to quantify EndoAnchor (Medtronic Vascular, Santa Rosa, Calif) penetration into the aortic wall in patients undergoing endovascular abdominal aortic aneurysm repair and to assess predictors of successful penetration and its relationship to postprocedural type IA endoleak. METHODS: A subset of patients from the Aneurysm Treatment Using the Heli-FX Aortic Securement System Global Registry (ANCHOR) were included if they met the following criteria: the indication for EndoAnchor use was to treat a type IA endoleak, and postprocedure contrast-enhanced computed tomography (CT) scans of sufficient quality were available for core laboratory review...

OBJECTIVE: The ideal treatment option for patients with complex aneurysm morphology remains highly debated. The aim of this study was to investigate the impact of endovascular aneurysm repair (EVAR) with active fixation on outcomes in patients with complex aneurysm morphology. METHODS: There were 340 consecutive patients who underwent EVAR using active fixation devices, 234 with active infrarenal fixation (AIF; Gore Excluder; W. L. Gore & Associates, Flagstaff, Ariz) and 106 with active suprarenal fixation (ASF; 85 Medtronic Endurant [Medtronic, Santa Rosa, Calif] and 21 Cook Zenith [Cook Medical, Bloomington, Ind])...

PURPOSE: To present a case of a patient with possible short (2 years approximately) life expectancy and a 68-mm abdominal aortic aneurysm with a large infrarenal neck and large suprarenal aorta that precluded chimney endovascular aortic repair (Ch-EVAR) treatment. MATERIALS AND METHODS: The technical aspects of a modification of the funnel technique (thoracic endograft as a proximal extension of a main infrarenal device in wide necks) are described. We advocated a migrated bifurcated 36-mm endograft in a 34-mm native aorta, ten mm below the lowest renal artery and added endoanchor (four) fixation to this "intentionally migrated main endograft...

BACKGROUND: Our objective was to quantify variability across the UK in the management of a complex abdominal aortic aneurysm (AAA). METHODS: An online survey was emailed to all members of the Vascular Society for Great Britain and Ireland. The survey presented a vignette of a 63-year-old woman with significant respiratory co-morbidity whose computed tomographic (CT) angiogram demonstrated a 54 mm AAA with a short (7 mm) proximal neck but no other adverse morphological features for a standard or complex endovascular aneurysm repair (EVAR)...

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger abdominal aortic aneurysm necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium of endovascular treatments is vast and increasing. Aside from provisional embolization of endoleaks or deferment to open repair conversion, attention should be directed toward obtaining adequate proximal and distal sealing...

OBJECTIVE: Hostile proximal aortic neck (HN) challenges the suitability for standard endovascular aneurysm repair (EVAR) of patients at high risk for "open" repair. However, there has been little if any focus placed on the individual role of the "nonlength" HN features in EVAR outcomes. The aim of this study was to evaluate their individual and potentially predictive role in outcomes of EVAR under HN conditions. METHODS: Data of 156 consecutive EVAR patients with short (<15 mm) HN, treated with the Endurant device (Medtronic Cardiovascular, Santa Rosa, Calif) at three European academic vascular centers between 2007 and 2015, were collected and retrospectively analyzed...

OBJECTIVE: Dilatation of the aorta within the proximal neck after endovascular aneurysm repair (EVAR) can be associated with late endoleaks and migration. This study was designed to identify predictors of early neck dilation in patients undergoing EVAR with Heli-FX EndoAnchors (Medtronic, Santa Rosa, Calif) measured perioperatively to 1 year at different longitudinal levels of neck length. METHODS: The study group of Aneurysm Treatment Using the Heli-FX Aortic Securement System (ANCHOR) comprises 257 consecutive patients prospectively enrolled between April 2012 and September 2014 undergoing EVAR with Heli-FX EndoAnchor implantation at 38 investigational sites...

As more challenging aortic arch anatomy is being treated using aortic stent-grafts, there is an increased risk for proximal Type I endoleaks at the proximal seal zone or subsequent graft migration. We report a case of an endoanchor-assisted thoracic endovascular aneurysm repair of a patient with an aberrant right subclavian artery (ARSA) and aortic arch aneurysm who developed a proximal Type I endoleak in the aortic arch which was subsequently treated with endoanchors.
