The study was carried out on 10 swine of 20-30 kg body weight. Five animals were assigned to each of 2 groups. An aneurysm of the abdominal aorta was created experimentally in animals from the first and second study group. After 4 weeks, animals from the second group were subject to aneurysm repair using an aortic prosthesis. During the experiment, we measured the myoelectric activity of the mu...

BACKGROUND Several percutaneous circulatory support systems have been recently introduced into clinical practice for the treatment of cardiogenic shock or refractory nontolerated ventricular tachycardia, in support of high-risk catheter interventions and, occasionally, cardiopulmonary resuscitation. To date, however, a direct comparison of the available systems has not been performed. METHODS...

Between 1972 and 1978, 31 patients underwent replacement of the ascending aorta, with or without aortic valve surgery, at the Wessex Regional Cardiac Centre. The commonest indications for operation were aneurysmal dilatation of the ascending aorta causing aortic regurgitation and acute dissection of the ascending aorta. Eleven of the 31 patients had features of Marfan's syndrome. The overall ho...

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...

This paper describes a novel approach to an objective measurement of aorta samples of rats and a quantitative evaluation of aorta-related drugs. Two-photon fluorescence microscopy is used for recording image sequences of deforming aorta. Time sequence snake models are used to track the structural deformations of aorta walls caused by drug stimulation of the elastic lamina in the aorta. Several ...

Chronic hyperinsulinemia is suspected of enhancing the development of arterial diseases. However, direct metabolic effects of insulin on the inner arterial wall are poorly documented. To assess the possible influence of variations in smooth muscle phenotype, we measured lipogenesis from glucose by rat thoracic aortas that had been injured with a balloon catheter. Aortas were exposed to insulin ...

We previously showed by qualitative en face autoradiography that after 24 hours of circulation, I-labeled low density lipoprotein (LDL) injected in tracer amounts accumulated focally at the edges of regenerating endothelial islands in the balloon catheter-deendothelialized aorta of the normocholesterolemic rabbit In the present study with the same animal model, we have used quantitative autorad...

Stenosis of the aorta observed after descending aorta replacement for traumatic aortic injury was managed by a placement of a bypass between the left subclavian artery and the distal descending aorta with success.

PURPOSE We aimed to perform intraindividual comparison of computed tomography (CT) parameters, image quality, and radiation exposure between standard CT angiography (CTA) and high-pitch dual source (DS)-CTA, in subjects undergoing serial CTA of thoracoabdominal aorta. METHODS Eighteen subjects with thoracoabdominal CTA by standard technique and high-pitch DS-CTA technique within 6 months of e...

BACKGROUND The temporal variation of the hemodynamic mechanical parameters during cardiac pulse wave is considered as an important atherogenic factor. Applying non-Newtonian blood molecular viscosity simulation is crucial for hemodynamic analysis. Understanding low density lipoprotein (LDL) distribution in relation to flow parameters will possibly spot the prone to atherosclerosis aorta regions...
