Notching Of The Ribs

	Notching Of The Ribs Notching of the ribs (or rib notching) is a radiologic sign where the surface of the rib is deformed. It can be characterized as unilateral or bilateral, and should be differentiated between affecting the upper (superior) or lower (inferior) surface of the rib. Causes Inferior rib notching can be associated with aortic coarctation (as a result of dilatation of intercostal arteries), superior vena caval obstruction, arteriovenous fistula, or following a Blalock Taussig shunt. Causes of inferior rib notching by etiology: ''Arterial'': aortic coarctation, aortic thrombosis, pulmonary-oligemia/arteriovenous malformation, Blalock Taussig shunt, Tetralogy of fallot (TOF), absent pulmonary artery, and pulmonary stenosis. ''Venous'': arteriovenous malformations of the chest wall, superior vena cava, or other central venous obstruction. ''Neurogenic'': intercostal neuroma, Neurofibromatosis type 1, poliomyelitis. ''Osseous'': hyperparathyroidism, thalassemia, Melnick–Needles syndro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon]
picture info	Radiologic Sign A radiologic sign is an objective indication of some medical fact (that is, a medical sign) that is detected by a physician during radiologic examination with medical imaging (for example, via an X-ray, CT scan, MRI scan, or sonographic scan). Examples * Double decidual sac sign * Face of the giant panda sign * Football sign * Golden S sign * Hampton's hump * Hilum overlay sign * Kerley lines * Mickey Mouse sign * Omental cake * Peribronchial cuffing * Pneumatosis intestinalis * Rigler's sign * Westermark sign In chest radiograph A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures.

picture info	Aortic Coarctation Coarctation of the aorta (CoA) is a congenital condition whereby the aorta is narrow, usually in the area where the ductus arteriosus (ligamentum arteriosum after regression) inserts. The word ''coarctation'' means "pressing or drawing together; narrowing". Coarctations are most common in the aortic arch. The arch may be small in babies with coarctations. Other heart defects may also occur when coarctation is present, typically occurring on the left side of the heart. When a patient has a coarctation, the left ventricle has to work harder. Since the aorta is narrowed, the left ventricle must generate a much higher pressure than normal in order to force enough blood through the aorta to deliver blood to the lower part of the body. If the narrowing is severe enough, the left ventricle may not be strong enough to push blood through the coarctation, thus resulting in a lack of blood to the lower half of the body. Physiologically its complete form is manifested as interrupted aortic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon]
	Intercostal Arteries The intercostal arteries are a group of arteries passing within an intercostal space (the space between two adjacent ribs). There are 9 anterior and 11 posterior intercostal arteries on each side of the body. The anterior intercostal arteries are branches of the internal thoracic artery and its terminal branchthe musculophrenic artery. The posterior intercostal arteries are branches of the supreme intercostal artery and thoracic aorta. Each anterior intercostal artery anastomose, anastomoses with the corresponding posterior intercostal artery arising from the thoracic aorta. Anterior intercostal arteries Origin The upper six anterior intercostal arteries are branches of the internal thoracic artery (anterior intercostal branches of internal thoracic artery). The internal thoracic artery then divides into its two terminal branches, one of which - the musculophrenic artery - proceeds to issue anterior intercostal arteries to the remaining 7th, 8th, and 9th intercostal spaces ...
