Abstract: Abdominal aortic aneurysm is a swelling (aneurysm) of the aorta. aneurysms often grow slowly without noticeable symptoms, so screening by clinical examination combined with imaging methods to detect disease early helps reduce morbidity and mortality. Computed tomography (CT) becoming increasingly common has become good method for detecting abdominal aneurysms. This study aims describe...

Background: Diastolic retrograde flow in the descending aorta has been associated to the severity of aortic regurgitation; however, most of the parameters related to flow velocity are not validated with a reference imaging technique. Objective: The aim of this study was to assess the usefulness of diastolic retrograde flow in the descending thoracic aorta and the abdominal aorta in the quantifi...

BACKGROUND Atherosclerosis is a progressive disease that causes vascular remodeling that can be positive or negative. The evolution of arterial wall thickening and changes in lumen size under current "standard of care" in different arterial beds is unclear. The purpose of this study was to examine arterial remodeling and progression/regression of atherosclerosis in aorta and carotid arteries of...

We have developed a method for constructing the geometry of morphologically realistic human aorta, including aortic root (Valsalva sinus), thoracic arch with branches, abdominal aorta bifurcation vessels. The creation three-dimensional model is necessary when planning surgical interventions, performing numerical modeling blood flow in aorta. anatomical structure differs different patients, espe...

Our male patient had a hypoplastic isthmus and a preductal coarctation of the aorta. The coarctation was corrected by resection and end-to-end anastomosis at the age of 3 months. The left subclavian artery was sacrificed in this procedure. Thirteen years later, a recoarctation involving the left carotid artery was diagnosed. Surgical correction was achieved with a preclotted Dacron knitted graf...

Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta, such that the diameter exceeds 3 cm. The natural history of AAA is progressive growth leading to rupture, an event that carries up to 90% risk of mortality. Hence there is a need to predict the growth of the diameter of the aorta based on the diameter of a patient's aneurysm at initial screening and aided by non-...

Ortner’s syndrome is a non-specific symptom of thoracic aortic aneurysm, therefore, it constitutes challenge — both, diagnostic and therapeutical for contemporary physicians. This paper presents the case 70-year-old patient reporting hoarse voice several months. Due to suspicion neoplastic disease, diagnostics were deepened during this diagnostic, an aneurysm descending aorta with concurrent in...

This study investigated the effects of hypertension on regional aortic biomechanical and structural properties in three rat models of vascular calcification: the hypertensive Lewis polycystic kidney (LPK; n = 13) model of chronic kidney disease, spontaneously hypertensive rats (SHRs; n = 12), and calcification in normotensive Lewis rats induced by vitamin D3 and nicotine (VDN; n = 8). Lewis and...
