Aorto-enteric Fistula Following Abdominal Aorta Surgery
… aorto-enteric fistuiae following abdominal aorta surgery are here recorded. A number of these have never before been recorded in the literature. For the first time sixteen cases of these aorto-enteric fistulae that were subjected to surgical intervention have been tabulated. Twelve of these …

Characterization of Heterogeneous Material Properties of Aorta Using Nanoindentation
… in the mechanical properties of porcine thoracic aorta wall in the radial direction were characterized using a quasi-linear viscoelastic modeling of nanoindentaiton tests. Two layers of equal thickness were mechanically distinguishable in descending aorta based on the radial variations in the …

MECHANICAL CHARACTERIZATION OF PORCINE AORTA USING MAGNETIC RESONANCE IMAGING
… in literature. DTI was also applied to a frozen aorta, where the structural parameters obtained were different from those for fresh tissue thus indicating the potential of DTI to measure damage in aortic tissue. MRI was also used for characterization of aortic tissue deformation, using Phase …

Dietary cholesterol, tissue phospholipids and prostacylin production of rat aorta
… blood samples, along with abdominal and thoracic aorta cross-sectional ring segments. were collected. The serum cholesterol levels, fatty acid compositions in the phospholipids (PL) of the aortic tissues (thoracic and abdominal aorta tissues combined), and the endogenous 6-keto-PGFla (stable …

A Computational Model of Aneurysmal Flow at the Abdominal Aorta
Abdominal Aortic Aneurysm is a dilatation of the aortic artery that occurs in response to degradation of the wall structure. The present research focused on developing a realistic hemodynamic model of the aneurysm using a new method to assign boundary conditions. A three element Windkessel model …

A Journey Through The Thoracic Aorta: From Root To Arch
… of disease of the aortic valve and the ascending aorta, including the aortic root. Purpose: The aortic valve and proximal aorta are the anatomical origin of the systemic circulation and pathology in this area can be catastrophic. Despite this, there is limited knowledge of the pathophysiology of …

Spontaneous rhythmic contractions in the coarcted aorta of hypertensive rats
… which had undergone a complete occlusion of the aorta between the origin of the renal arteries. Eight days post-occulsion, measurements in awake rats showed that arterial pressure in the thoracic aorta (pressure-loaded region) was 168.35 $\pm$ 1.28 mm Hg (n = 104), while in the abdominal aorta …

Histopathologische Untersuchungen von Aneurysmen der Aorta ascendens in Abhängigkeit von Aortenklappenvitien
… at the concave curvature of the ascending aorta. AS-AAAs present significant higher mean GMC deposits than AR-AAAs. Combined with a bicuspid morphology of the aortic valve, GMC deposition in AAAs is elevated in comparison to AAAs with TAV morphology. Therefore AS-AAAs with BAV have the …
