Simultaneously measurements of intra-arterial pressure and external diameter were recorded from the thoracic and abdominal aortas, the carotid, brachiocephalic, left subclavian, and femoral arteries of anesthetized dogs. Data were recorded under control conditions and during efferent vagal stimulation, and were used to compute values of wall geometry, mechanical properties, phase velocity, and ...

BACKGROUND If undetected, infrarenal Abdominal Aortic Aneurysm (AAA) growth can lead to rupture, a high-mortality complication. Some AAA patients exhibit inhomogeneous luminal contrast attenuation at first-pass CT angiography (CTA). This study assesses the association between this observation and aneurysm growth. METHODS Sixty-seven consecutive pre-repair AAA CTAs were included in this retros...

OBJECTIVE Pericardial adipose tissue (PAT), a regional fat depot adjacent to the myocardium, may mediate the complex relation between obesity and cardiac left ventricular (LV) abnormalities. We sought to evaluate the association of PAT with echocardiographic measures of LV abnormalities in the Jackson Heart Study (JHS). RESEARCH DESIGN AND METHODS A total of 1,414 African Americans (35% men; ...

This conducted Najran province (K.S.A), archival abdomin...

Background Hydatid cyst is caused by the tapeworm Echinococcus granulosus. The abdomen, specifically the liver, is the most common site affected. Objective Determine the presentation patterns, types of surgical management, and outcomes of patients operated for intra-abdominal hydatid cyst (IAHC). Methodology A retrospective descriptive study of patients admitted and operated for IAHC from S...

The static elastic properties of arterial tree (abdominal aorta and common carotid artery) were studied in 19 normal subjects and in 49 patients with myocardial infarction with an ultrasonic phase-locked echo-tracking system that allows continuous transcutaneous measurement of the arterial diameter. The stiffness index beta, which represented the mechanical properties in the arterial wall, was ...

The stifTness index (, which represented the mechanical properties in the arterial wall, was cal...

OBJECTIVE Most studies recommend repair of renal artery aneurysms (RAAs) >2 cm in diameter in asymptomatic patients, but other studies have suggested that their natural history may be more benign. We hypothesized that rupture and death in patients with asymptomatic RAAs is low and that current recommendations for RAA treatment at 2 cm may be too aggressive. METHODS Retrospective review of all...

OBJECTIVE We evaluated the association between patients' weight and abdominal cross-sectional dimensions and CT image quality. MATERIALS AND METHODS We prospectively evaluated 39 cancer patients aged more than 65 years with multislice CT scan of abdomen. All patients underwent equilibrium phase contrast-enhanced abdominal CT with 4 slices (from top of the right kidney) obtained at standard tu...
