Abstract Traumatic descending thoracic aorta pseudo aneurysms have been treated traditionally with open surgery in the past, which have had noticeable rates of mortality and morbidity. A safer method of treatment for this disease is made possible with recent progress in endovascular treatment techniques. In this article, we present three cases of Traumatic descending thoracic aorta pseudo aneu...

The pharmacological properties and mechanism of the action of protopine on isolated rat thoracic aorta were examined. It inhibited norepinephrine (NE, 3 microM)-induced tonic contraction in rat thoracic aorta in a concentration-dependent manner (25-100 micrograms/ml). The phasic contraction caused by NE was inhibited only by a high concentration of protopine (100 micrograms/ml). At the plateau ...

aortic dissection begins with the formation of a tear in the aortic intima, and it directly exposes an underlying diseased medial layer to the driving force of the intraluminal blood. this blood penetrates the diseased medial layer and cleaves the media longitudinally, thereby dissecting the aortic wall. herein, we report the case of a 38-year-old woman, who presented with chest pain and dyspne...

background multiple classifications can be used to define the magnitude of aortic injury. the vancouver classification (vc) is a new and simplified computed tomography-based blunt aortic injury (bai) grading system correlating with clinical outcomes. objectives the objectives of this study are: 1) to describe the severity of aortic injury in a center with a predominantly surgical approach to ba...

conclusions troxerutin may reduce the vascular complications and tissue injuries induced by chronic diabetes in rat aorta through increasing the activity of tissue antioxidant system and reducing the level of lipid peroxidation. materials and methods male wistar rats were randomly divided into four groups (n = 8/each): control, control plus troxerutin, diabetic and diabetic plus troxerutin. dia...

Mycotic aneurysms are localized and irreversible dilatations of the arteries caused by weakening and damaging the arterial wall by an invasive organism establishing infective arteritis. Mycotic aneurysm of the thoracic aorta is a rare event; however, it can be fatal if not diagnosed early or not treated appropriately. Clinical findings are usually nonspecific; however, c...

The influence of estradiol upon incorporation of isotopes into the sulfated acid mucopolysaccharides of connective tissues of the rat has been studied. Administration of the hormone for 3 weeks significantly reduces the in vitro incorporation of S(35)-sulfate into cartilage and thoracic aorta without significantly altering the amount of hydrolyzable sulfate in these tissues. The reduction of su...

Helically cut thoracic aortic strips (from rats, rabbits, and guinea pigs) in a state of low to moderate tone and under the influence of alpha-receptor blockade relaxed in response to isoproterenol. Propranolol blocked these relaxations. Helically cut thoracic aortic strips from cats and abdominal aortic strips from rats, rabbits, and cats were not relaxed by isoproterenol. In addition, aortic ...

The influence of secretin (10(-10) - 10(-8) M), a gastrointestinal hormone, on the relaxing response of rat thoracic aorta rings preconstricted by 40 mM KCl was studied by measuring changes in isometric tension in intact and diabetic animals. Initial contraction of aorta rings was markedly decreased in diabetic state. Secretin administered at two higher doses (10(-9), 10(-8) M) caused significa...
