Age is a well-known risk factor for postoperative death in patients with abdominal aortic aneurysms (AAA), and the efficacy of open aneurysm repair (OAR) and endovascular aneurysm repair (EVAR) remains controversial in the elderly population. The aim of this study was to determine the predictors of 30-d mortality after AAA repair in elderly population.
The aim of the study was to compare long-term total and aneurysm-related mortality in physically frail patients with abdominal aortic aneurysm (AAA) randomized to either early endovascular aneurysm repair (EVAR) or no-intervention.
We aim to describe trends in failure to rescue (FTR) among elderly patients undergoing elective open aortic aneurysm repair (OAR) and endovascular aortic aneurysm repair (EVAR).
Abdominal aortic aneurysm (AAA) is a common disease seen in vascular units. AAA is defined as transverse diameter greater than 3 cm and affects men more than women. Endovascular aortic aneurysm repair (EVAR) is increasingly being used to treat AAA. Renal dysfunction, graft-related endoleaks, graft limb occlusion, device migration and delayed aneurysm rupture are possible complications that have been encountered after EVAR.
People with abdominal aortic aneurysm who receive endovascular aneurysm repair (EVAR) need lifetime surveillance to detect potential endoleaks. Endoleak is defined as persistent blood flow within the aneurysm sac following EVAR. Computed tomography (CT) angiography is considered the reference standard for endoleak surveillance. Colour duplex ultrasound (CDUS) and contrast-enhanced CDUS (CE-CDUS) are less invasive but considered less accurate than CT.
Endoleak is a common complication of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) but can be detected only through prolonged follow-up with repeated aortic imaging. This study examined the potential for circulating matrix metalloproteinase 9 (MMP9), osteoprotegerin (OPG), D-dimer, homocysteine (HCY), and C-reactive protein (CRP) to act as diagnostic markers for endoleak in AAA patients undergoing elective EVAR.
Objective Reports on inflammatory aortic abdominal aneurysm treatment are scarce. Traditionally, open surgery has been validated as the gold standard of treatment; however, high technical skills are required. Endovascular aortic repair has been suggested as a less invasive treatment by some authors offering good results. The purpose of our study was to report our experience and outcomes in the treatment of inflammatory aortic abdominal aneurysm using both approaches. Material and methods A retrospective rev...
The introduction of endovascular aneurysm repair (EVAR) has reduced perioperative mortality after abdominal aortic aneurysm (AAA) surgery. The objective of this systematic review was to assess existing mortality risk prediction models, and identify which are most useful for patients undergoing AAA repair by either EVAR or open surgical repair.
The purpose of this report is to describe the synchronous surgical treatment of an abdominal aortic aneurysm (AAA) with concomitant esophageal cancer (EC) with a three-stage esophagectomy, a real management challenge especially in establishing the therapeutic priorities and the ideal treatment approach. A 65-year old male was referred for treatment in our hospital with the diagnosis of AAA. He complained of general fatigue, weight loss and intermittent dysphagia. Contrast-enhanced CT and upper endoscopy sho...
Although the indications for endovascular aneurysm repair for abdominal aortic aneurysm have been expanding, our primary strategy for pararenal and juxtarenal abdominal aortic aneurysm (P/JRAA) is open surgery (OS). One consequence of OS for P/JRAA is transient renal ischemia owing to renal artery clamping, which can be followed by acute kidney injury (AKI). Prior studies referred to the impact of renal ischemia on AKI, but they have rarely evaluated longer-term renal function. This study focused on a chron...
To test the hypothesis that retinal microvascular abnormalities known to predict other cardiovascular diseases are associated prospectively with risk of abdominal aortic aneurysm. The rationale is that aortic aneurysm involves small vessel pathology that parallels, to some degree, retinal vasculopathy.
The prevalence of abdominal aortic aneurysm (AAA) is reported to be 2.2%-8% among men >65 years. During recent years, screening programs have been developed to detect AAA, prevent ruptures, and thereby saving lives. Therefore, most men with the diagnosis are monitored conservatively with regular reviews. The objective of the study was to describe how men diagnosed with abdominal aortic aneurysm
To determine the incidence and risk factors of renal dysfunction after abdominal endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR).
Abdominal aortic aneurysm (AAA), frequently diagnosed in old patients, is characterized by chronic inflammation, vascular cell apoptosis and metalloproteinase-mediated extracellular matrix destruction. Despite improvement in the understanding of the pathophysiology of aortic aneurysm, no pharmacological treatment is yet available to limit dilatation and/or rupture. We previously reported that human gingival fibroblasts (GFs) can reduce carotid artery dilatation in a rabbit model of elastase-induced aneurysm...
Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms exposes patients and healthcare professions to the deterministic and stochastic effects of ionization radiation. The study aim was to determine our standard of radiation exposure in infrarenal EVARs and compare it against other published data and national guidelines.
Abdominal aortic aneurysms pose a substantial clinical burden, and a significant proportion are not anatomically suitable for open repair or standard endovascular aneurysm repair (EVAR), instead requiring fenestrated EVAR (fEVAR). We sought to compare clinical outcomes and trends over time in patients undergoing fEVAR in Australia.
In very rare cases, a primary infected abdominal aortic aneurysm (IAAA) is caused by a species of Brucella. In this report, we report such a case that was successfully treated with a novel approach. To the best of our knowledge, this was the first case occurring in China, in which an infection of the abdominal aortic aneurysm was caused by a Brucella species.
Patients undergoing endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms can exhibit variations in sac behavior ranging from complete regression to expansion. We evaluated the impact of sac behavior at 1-year follow-up on late survival.
Although few studies have reported outcomes after branched or fenestrated endovascular aortic aneurysm repair (FEVAR) of abdominal aortic aneurysms involving visceral vessels (AAA-Vs), no multi-institutional study has compared FEVAR with open surgery (OS) for AAA-Vs. Our objective was to compare 30-day outcomes after FEVAR vs OS for AAA-Vs.
The Rapid Ruptured Abdominal Aortic Aneurysm Score (RrAAAs) was developed from Vascular Study Group of New England (VSGNE) data (649 rAAA patients, repaired both open and endovascularly), using pre-operative age, creatinine, and blood pressure. This study validates that model using the larger National Vascular Quality Initiative (VQI) dataset, and compares its performance to previous models.
The number of aorta procedures performed annually in the United States has grown substantially during the past decade. Cleveland Clinic is a leader in research on the risk of aortic dissection in patients with a bicuspid or tricuspid aortic valve and associated aneurysm, which has led to changes in the recommendations of when to operate. Safety and efficacy data support more proactive treatment for most patients with thoracic aortic aneurysm and/or dissection with a growing emphasis on the need to provide l...
Abdominal aortic aneurysms are usually asymptomatic. The compressive effects of internal iliac aneurysms are well described in the literature, however, we report what we believe to be the first case of rupture of the renal pelvis caused by compression by an infra-renal abdominal aortic aneurysm. We describe the subsequent management and briefly review the literature.
Shprintzen-Goldberg syndrome is a rare systemic connective tissue disorder characterized by craniosynostosis, skeletal abnormalities, infantile hypotonia, mild-to-moderate intellectual disability and cardiovascular anomalies. To our knowledge, this is the first report of a Shprintzen-Goldberg syndrome patient who developed a thoraco-abdominal aortic aneurysm. The aneurysm grew rapidly necessitating emergent thoraco-abdominal aortic replacement. The postoperative course was uneventful, and a careful lifetime...
Mr AB is a 66-year old gentleman who presented for elective endovascular aneurysm repair (EVAR) following a routine screening scan identifying a 5.5cm abdominal aortic aneurysm (AAA). He had a past history of chronic obstructive pulmonary disease (COPD) with FEV1/FVC ratio of 48% on pre-assessment. He was hypertensive with a history of ischaemic heart disease (IHD), which has remained asymptomatic following coronary artery bypass grafting (CABG) eight years prior to this presentation.
We report a preliminary experience about endovascular aortic repair (EVAR) of infrarenal abdominal aneurysm (iAAA) with severe proximal aortic neck angulation using the Aorfix(TM) stent graft.
