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

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.

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.

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

Eighteen (58%) were associated with a non-contiguous abdominal aortic aneurysm, four being unilateral and seven bilateral femoral aneurysms (group 2).

Abstract:

Abdominal aortic aneurysms are a common health problem and currently the need for surgical intervention is determined based on maximum diameter and growth rate criteria. Since these universal variables often fail to predict accurately every abdominal aortic aneurysms evolution, there is a considerable effort in the literature for other markers to be identified towards individualized rupture risk estimations and growth rate predictions. To this effort, biomechanical tools have been extensively used since abdominal aortic aneurysm rupture is in fact a material failure of the diseased arterial wa

Abstract:

Inflammation plays a part in the development of abdominal aortic aneurysm (AAA), and the gut microbiota affects host inflammation by bacterial translocation. The relationship between abdominal aortic aneurysm and the gut microbiota remains unknown. This study aimed to detect bacterial translocation in the aneurysmal wall and blood of patients with abdominal aortic aneurysm, and to investigate the effect of the gut microbiota on abdominal aortic aneurysm. We investigated 30 patients with abdominal aortic aneurysm from 2017 to 2019. We analysed the aneurysmal wall and blood using highly sensitiv

Abstract:

The purpose of this study was to examine the changing trends in surgical management of patients with abdominal aortic aneurysms at a tertiary care teaching hospital over the past 40 years, by analysis of demographic data, perioperative variables and outcomes on all patients having abdominal aortic aneurysm surgery between 1955 and 1993. Some 1604 abdominal aortic aneurysms were assessed. The annual rate of abdominal aortic aneurysm surgery increased from 17.6 to 67.8 cases per year. The non-ruptured to ruptured abdominal aortic aneurysm ratio increased from 2.4: 1 in the first decade to 3.4: 1

Abstract:

Aortic aneurysms are relatively common maladies that may lead to the devastating consequence of aortic rupture. AAAs (abdominal aortic aneurysms) and TAAs (thoracic aortic aneurysms) are two common forms of aneurysmal diseases in humans that appear to have distinct pathologies and mechanisms. Despite this divergence, there are numerous and consistent demonstrations that overactivation of the RAS (renin–angiotensin system) promotes both AAAs and TAAs in animal models. For example, in mice, both AAAs and TAAs are formed during infusion of AngII (angiotensin II), the major bioactive peptide in th

Background: Besides biological factors, abdominal aortic aneurysm rupture is also caused by mechanical parameters, which are constantly affecting the wall’s tissue due to their abnormal values. The ability to evaluate these parameters could vastly improve the clinical treatment of patients with abdominal aortic aneurysms.
