Ultrasound in the diagnosis of aortic dissection of the role


Layer separation tends to occur in the thoracic aorta ,ralph lauren deutschland, abdominal aorta can be extended to most of dissection of DeBakeyI type (involving the ascending aorta , aortic arch , descending aorta and abdominal aorta ),moncler jacken, nlb -type ( confined to the descending aorta , extending to the abdominal aorta ) , a small part of DeBakey Ⅱ type ( lesions confined to the aortic arch ) and ma -type ( confined to the descending aorta ) . Aortic dissection can be found in the tear , but also could not find the break . Identify true and false lumen dissection is important , but not complicated , by the following methods to determine : ( 1 ) to see the movement of intimal tear , intimal tear in the same direction with the movement of the false lumen wall , the relative motion true cavity wall ; (2 ) observed lesions of the aorta wall section and the continuity of the normal , and normal true lumen is continuous cavity ; (3 ) color Doppler , appear bright red high-speed flow is true lumen , appear dark blue blood or no blood flow shows false lumen , false lumen flow rate can be slow due to the emergence of more clots . Dissection with acute abdomen due to similar clinical symptoms , it needs to be identified , through the pulsating mass of the characteristic features and differences. The dissection and aortic aneurysm due to aortic dilatation similar clinical symptoms and the common expression , they will have to based on the differential presence or absence of hyperechoic band of light . Dissection distal intimal rupture , pain can be alleviated. If persistent or recurrent pain , you need to alert the outer wall of blood vessels may rupture . Dissection through the X-ray , CT,ugg pas cher, MR /, aortic angiography ,nike free run, DSA, ultrasound to diagnose , while ultrasound diagnosis because of its non-invasive, simple, rapid ,nike free run, economic, and image characteristics of clear and reliable , fully as dissection the preferred diagnostic method.
