BACKGROUND: Ultrasound screening shows a clinical benefit in reducing abdominal aortic aneurysm (AAA)-related mortality. However, its cost-effectiveness remains unclear. Understanding the relationship between risk factors and AAA is important to maximize the benefit of AAA screening. However, risk factors for AAA have not been reported in Korea. The purpose of this study was to determine the prevalence of and risk factors for AAA among the Korean population. METHODS: The study population consisted of patients >50 years of age who consented for AAA screening...

BACKGROUND: As endovascular aneurysm repair (EVAR) continues to advance, eligibility of patients with anatomically complex abdominal aortic aneurysms (AAAs) for EVAR is increasing. However, whether complex EVAR is associated with favorable outcome over conventional open repair and how outcomes compare with infrarenal EVAR remains unclear. This study examined perioperative outcomes of patients undergoing complex EVAR, focusing on differences with complex open repair and standard infrarenal EVAR...

PURPOSE: To report the outcomes of fenestrated endovascular aneurysm repair (FEVAR) and compare early and midterm results in relation to stent-graft complexity. METHODS: Between August 2006 and December 2014, 141 consecutive patients (mean age 72±7.6 years, range 50-89; 120 men) were treated electively with FEVAR for short-neck, juxtarenal, or suprarenal aortic aneurysms. Forty-five patients treated with stent-grafts featuring renal-only fenestrations were assigned to group A, while 96 patients receiving additional fenestrations for the superior mesenteric and/or celiac arteries were assigned to group B...

PURPOSE: To describe a technique suitable for treating severely angulated (>75°) necks during endovascular aneurysm repair using the Endurant stent-graft. TECHNIQUE: In the push-up technique, the suprarenal stent is released early to fix the proximal stent-graft in place so that each stent in the neck can be deployed individually without displacing the device upward. It is important to push the delivery system up after each stent deployment to allow the fabric between the stents to fold up circumferentially...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...

OBJECTIVE: Although endovascular repair of ruptured abdominal aortic aneurysms (rAAAs) is increasingly more prevalent and may yield better results, open repair of rAAAs is still commonly performed. Our goal was to assess the contemporary practice patterns and outcomes of open repair of rAAA. METHODS: The 2011-2014 American College of Surgeons National Surgical Quality Improvement Program targeted open AAA database was queried for all rAAAs. Patient characteristics, presentation, aneurysm details, and operative details were analyzed to identify factors that may affect outcome in this population of patients...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

BACKGROUND: These last years, considerable attention has been given to renal issues following endovascular aortic repair but acute kidney injury (AKI) also remains one of the most frequent complications following open repair (OR). Since AKI definition has evolved, our aim was to review the etiology, incidence, classifications, and consequences of AKI after OR for intact abdominal aortic aneurysm (AAA). METHODS: A review of the English language literature published between 2004 and 2016 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria...

BACKGROUND: Ovation aortic stent-graft system is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid anchored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings, which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new design. Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the ovation in 3 patients...

BACKGROUND: Abdominal aortic aneurysm (AAA) affects more than 5% of the population in developed countries. To study the formation and progression of AAA, we developed a non-invasive method to analyse regional aortic stiffness to monitor the formation and progression of AAA. METHODS: Saline or Angiotensin II (AngII) was subcutaneously infused in apolipoprotein E knockout (ApoE(-/-)) mice for 28 days; a high-resolution imaging system was used to identify changes in arterial stiffness measured by pulse-wave velocity (PWV) and aortic lumen diameter in the suprarenal aorta...

Angiogenesis and inflammation are implicated in aortic aneurysm and atherosclerosis and regulated by angiopoietin-2 (Angpt2). The effect of Angpt2 administration on experimental aortic aneurysm and atherosclerosis was examined. Six-month-old male apolipoprotein E deficient (ApoE(-/-)) mice were infused with angiotensin II (AngII) and administered subcutaneous human Fc-protein (control) or recombinant Angpt2 (rAngpt2) over 14 days. Administration of rAngpt2 significantly inhibited AngII-induced aortic dilatation and rupture of the suprarenal aorta (SRA), and development of atherosclerosis within the aortic arch...

OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. METHODS: We have reviewed all consecutive endograft explants for infection at 11 French university centers following EVAR, defined as index EVAR, from 1998 to 2015. Diagnosis of infected aortic endograft was made on the basis of clinical findings, cultures, imaging studies, and intraoperative findings...

RATIONALE: Uncontrolled growth of abdominal aortic aneurysms (AAAs) is a life-threatening vascular disease without an effective pharmaceutical treatment. AAA incidence dramatically increases with advancing age in men. However, the molecular mechanisms by which aging predisposes individuals to AAAs remain unknown. OBJECTIVE: In this study, we investigated the role of SIRT1 (Sirtuin 1), a class III histone deacetylase, in AAA formation and the underlying mechanisms linking vascular senescence and inflammation...

Importance: Epidural analgesia (EA) is used as an adjunct procedure for postoperative pain control during elective abdominal aortic aneurysm (AAA) surgery. In addition to analgesia, modulatory effects of EA on spinal sympathetic outflow result in improved organ perfusion with reduced complications. Reductions in postoperative complications lead to shorter convalescence and possibly improved 30-day survival. However, the effect of EA on long-term survival when used as an adjunct to general anesthesia (GA) during elective AAA surgery is unknown...

OBJECTIVE: The influence of endovascular aneurysm repair (EVAR) on renal function is of high concern. The question whether stent graft fixation type plays a significant role in renal outcome after EVAR is still debated. However, other factors, such as repeated contrast medium exposure, should also be considered. METHODS: We performed a two-center, stratified-cohort case control study to evaluate the influence of last-generation abdominal endografts with suprarenal (SR) vs infrarenal (IR) fixation on renal function...
