Abstract:

The high incidence of aneurysms of different arterial systems in case of abdominal aortic aneurysm causes the need for the examination of all patients with aortic aneurysm in order to detect aneurysmal process in all main arteries. The use of the mentioned predictors of aneurism wall failure in daily clinical practice provides an opportunity to improve the results of surgical treatment. Active surgical approach in relation to aortic aneurysm and main arteries is indicated in the presence of aneurismal disease. The choice of treatment depends on the severity of the patient’s condition, clinical

Abstract:

Aortic disease is a collection of diseases of the aorta, which includes aortic aneurysms; acute aortic infections consisting of aortic dissection, intramular hematoma, penetration of atherosclerotic ulcers (PAU) and traumatic injury to the aorta; pseudoaneurysm; aortic rupture; Marfan syndrome; and congenital abnormalities such as coarctation of the aorta. One of the aortic diseases that cause the death rate to increase according to the 2010 Global Burden Disease is aortic aneurysm. Abdominal aortic aneurysm (AAA) is a focal dilatation of the aortic segment. The diagnosis of AAA is done by his

Abstract:

Introduction. Abdominal aortic aneurysm diameter is one of the most important parameters in the diagnostic and therapeutic algorithm for aneurysm follow-up. Currently, two therapeutic modalities are used: open surgery and endovascular aortic repair. The aim of this study is to analyze the impact of the maximum transverse diameter of the abdominal aortic aneurysm on the incidence of general and specific complications. Material and Methods. The retrospective study included 75 patients with infrarenal abdominal aortic aneurysm who underwent endovascular aortic repair in the period from July 2008

Abstract:

The infrarenal abdominal aortic aneurysm is the most common among arterial aneurysms; it happens when there is an abnormal and irreversible enlargement of the blood vessel. This disease usually compromises other arterial segments and is linked to high mortality rates, mainly due to its rupture. Given its importance, we present a case study of an abdominal aortic aneurysm associated with a common iliac artery aneurysm. During a dissection practice in the Morphofunctional Laboratory at FACERES Medical School, we observed the presence of a mild stenosis in the abdominal aorta below the renal arte

Purpose: To develop an animal model for the acute and chronic monitoring of pressure within abdominal aortic aneurysms (AAAs) to be treated with endovascular grafts. Methods: A strain-gauge pressure transducer was placed within an AAA created from a prosthetic vascular graft. Prosthetic aneurysms were implanted into 17 canine infrarenal aortas. The intra-aneurysmal pressure was monitored and correlated with noninvasive forelimb sphygmomanometry for 2 weeks. After this time, an intravascular manometer catheter was passed into the aneurysm. Simultaneous pressure measurements were obtained using

Abstract:

Abdominal aortic aneurysms (AAA) are the most common arterial aneurysms. Endovascular or open surgical aneurysm repair is indicated in patients with large AAA ≥ 5.5 cm in diameter as this prevents aneurysm rupture. The presence even of small AAAs not in need of immediate repair is associated with a very high cardiovascular risk including myocardial infarction, stroke or cardiovascular death. This risk by far exceeds the risk of aneurysm rupture. These patients therefore should be considered as high-risk patients and receive optimal medical treatment and life-style modificiation of their cardio

Abstract:

Aneurysmal dilatation of the femoral artery is a rare condition of uncertain aetiology. Between January 1972 and December 1992, 31 atherosclerotic femoral aneurysms in 22 patients were seen. There were 21 men and 1 woman; mean(s.d.) age was 70.1(10.4) years. Thirteen (42%) femoral aneurysms (group 1) were isolated aneurysms, two being bilateral. Eighteen (58%) were associated with a non-contiguous abdominal aortic aneurysm, four being unilateral and seven bilateral femoral aneurysms (group 2). The mean(s.d.) size of these aneurysms was 4.7(1.5) and 3.5(0.7) cm in groups 1 and 2 respectively (

Abdominal Aortic Aneurysms (AAA) are amongst the top ten most common cause of death in those over 55 years of age. The disease is usually asymptomatic, often being diagnosed incidentally. Once diagnosed, elective repair of an AAA results in excellent long-term survival with a 3-5% operative mortality. However, up to one half of patients present with ruptured aneurysms, a complication that carries an 80% mortality in the community, and of those reaching hospital, a 50% mortality.

Abstract:

Aortic aneurysm is a pathological dilatation of the aorta that can be life-threatening when it ruptures. Aneurysms occur throughout the entire aorta but there is a predisposition for the ascending and the abdominal aorta, an observation that cannot be fully explained by the current knowledge of the disease pathophysiology. ApoE −/− mice infused with angiotensin II have recently been reported to develop not only abdominal [1], but also ascending aortic aneurysms [2]. These animals thus provide the perfect model to compare aneurysm progression in both aortic locations and to investigate whether

The prevalence of AAA is growing along with population age and according to different studies AAA rupture is the 13th most common cause of death in the U.S., causing an estimated 15,000 deaths per year. In biomechanical terms, AAA rupture is a phenomenon that occurs when the developing mechanical stresses within the aneurysm inner wall, as a result of the exerted intraluminal pressure, exceed the failure strength of the aortic tissue. To obtain a reliable estimation of wall stress, it is necessary to perform an accurate three-dimensional reconstruction of the AAA geometry and model an appropri

Abstract:

Every year in the United States, 4,500 deaths occur from abdominal aortic aneurysm (AAA) rupture. Aneurysms develop when the arterial wall weakens. Many risk factors can contribute to aneurysm formation, including age, sex, ethnicity, smoking and hypertension [1]. AAAs are the most common form of aneurysm because the aorta experiences the highest wall shear stress (WSS) of any vessels in the human body. These aneurysms are 5–6% prevalent in men and 1–2% in women, both over 65 years of age [2]. In the aorta, high WSS causes plaque formation, but in peripheral arteries where the flow rate is low

When the aneurysm grows to a diameter of 5.0–5.5 cm or is shown to expand at a rate greater than 1 cm/yr, elective operative repair is undertaken. While this strategy certainly prevents a number of potentially catastrophic ruptures, AAA rupture can occur at sizes less than 5 cm. From a biomechanical standpoint, aneurysm rupture occurs when wall stress exceeds wall strength. By using non-invasive techniques, such as finite element analysis (FEA), wall stress can be estimated f

Abstract:

Abstract Abdominal aortic aneurysm (AAA) is a condition whereby the terminal aorta permanently dilates to dangerous proportions, risking rupture. Rupture of AAA is a significant cause of death in this country that is generally avoided by surgical repair. In order to improve our understanding and diagnosis of this disease, we call upon first principles of finite elasticity. We use such principles to estimate the AAA wall strength and acting wall stress, which in turn allow evaluation of an individual aneurysm’s risk of rupture. In this paper, we summarize the work that has been performed to dat

Abstract:

There has been a clear need for better understanding of the progression of abdominal aortic aneurysm (AAA) and obtaining reliable prediction of the AAA rupture. Finite element analysis (FEA) using non-axisymmetric models of AAAs provides better estimation of stress distribution in the aneurysmal wall with complex shapes [1]. However, FEA alone does not provide a mathematical description for the evolution of an AAA through growth and remodeling (G&R). A computational framework for modeling stress-mediated growth and structural remodeling of the arterial wall under physiological and patholog

Abstract:

Abstract Abdominal Aortic Aneurysms (AAAs) are balloon-shaped expansions commonly found in the infrarenal segment of the abdominal aorta, between the renal arteries and the iliac bifurcation. The mean age of patients with AAA is 67 years and males are affected more often than women in a ratio of 4:1. Abdominal aortic aneurysm rupture is the 13th leading cause of death in the United States, affecting 1 in 250 individuals greater than 50 years of age. AAAs usually remain asymptomatic while slowly enlarging over a period of years or even decades. Factors that are known to affect the risk of aneur

Abstract:

Rupture of abdominal aortic aneurysm (AAA) is the 13th leading cause of death in western society and is fatal in 70–90%. In consequence, precise prediction of AAA rupture risk is essential. With the current, well established CT-morphological parameters such as maximum aortic diameter, aneurysm shape and AAA expansion, only at best the relative, but not the individual rupture risk can be determined. Hence, AAA rupture may occur unexpectedly in small aneurysms below the critical diameter limits whereas many large aneurysms may remain stable throughout patient’s lifetime, without prophylactic sur
