Endovascular aneurysm repair (EVAR) using stent grafts has shown to be an effective alternative to surgical repair in treating an abdominal aortic aneurysm (AAA). EVAR is associated with shorter hospital stays, less blood loss, shorter operating times, and lower early morbidity and mortality compared to open surgical repair, although EVAR required a higher reintervention rate during a longer fo...

The novel three-dimensional mathematical model for the development of an abdominal aortic aneurysm (AAA) (Watton et al. 2004) describes how changes in the micro-structure of the arterial wall lead to the development of the AAA, as collagen remodels to compensate for the loss of elastin. In this paper, we model the development of an axisymmetric aneurysm and compare the growth rates and changes ...

Background—The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success. We evaluated compliance with anatomic guidelines for EVAR and t...

BACKGROUND Abdominal aortic aneurysm (AAA) is a severe disease that can prove fatal. Factors such as advanced age, male gender, family history and cigarette use increase the risk of AAA. These factors associated with AAA development also increase arterial stiffness. Aortic pulse-wave velocity (PWV) was measured as an index of aortic stiffness. The heart rate-corrected augmentation index (AIx@75...

We report a rare complication of acute onset paraplegia after repair of an abdominal aortic aneurysm in a patient with acute type B aortic dissection. A 53-year-old man, suffering from abdominal aortic aneurysm (AAA), was admitted to our hospital with type IIIB acute aortic dissection. Ten days after admission, emergency Y-grafting was performed for impending rupture of the AAA. Twenty hours af...

Aim: Ruptured abdominal aortic aneurysm (AAA) is among the surgical emergencies with highest mortality, generally causes death in 90% of cases. Most AAA ruptures open into retroperitoneal space, and are recognized by classical triad pain, hypotension, a pulsatile mass. Unfortunately, only 25% to 50% patients present this triad; thus, many ruptured either remain undiagnosed or falsely diagnosed ...

Abdominal aortic aneurysm (AAA), an inflammatory disease, involves leukocyte recruitment, immune responses, inflammatory cytokine production, vascular remodeling, neovascularization, and vascular cell apoptosis, all of which contribute to aortic dilatation. This study demonstrates that mast cells, key participants in human allergic immunity, participate in AAA pathogenesis in mice. Mast cells w...

A systematic review and meta-analysis of Mendelian randomization studies using Medline, Cumulative Index to Nursing Allied Health Literature Complete, Scopus databases. Sixteen involving 34,050 patients with an abdominal aortic aneurysm (AAA) 2,205,894 controls were included. Meta-analyses suggested that a 1 standard deviation increase in high-density lipoprotein cholesterol (HDL-C) significant...
