Acute aortic dissection on CT: is D-dimer determination useful for a timely and correct diagnosis? A case reportdoi:10.1186/s12245-025-00811-9D-dimerThoracic Aorta DissectionChest PainsChest pain is a common reason patients are admitted to the hospital. The most clinically significant cases are ...
Dissection involving the ascending aorta has an extremely high mortality (up to 1% per minute, 60% in 60 minutes). Thus, time-consuming investigations that are not sufficiently sensitive or specific, such as computed tomography (CT), must be forsaken. Emergency surgery carries the only hope of...
Traumatic Forms of Aortic Dissection Traumatic Aortic Injury Although the majority of traumaticaortic injuriesare diagnosed by CT, the advantages of TEE for diagnosing traumaticaortic injuryare multiple: it is portable; can be performed at the bedside or in the operating room; can provide an immediat...
主动脉夹层(aortic dissection)指主动脉腔内的血液通过内膜的破口进入主动脉壁中层而形成的血肿,并非主动脉壁的扩张, … www.wiki8.com|基于584个网页 2. 主动脉剥离 又称主动脉剥离(aortic dissection)。因主动脉的管壁中层发生剥离,使得血液不断涌入管壁中因剥离所造成的空隙内所形成。
A predictive model was created and tested on an additional 120 CT scans from 115 patients. Statistically significant features of AAD included periaortic confluent soft tissue opacity, curved dissection flap, and highly mobile dissection flap, and features of CAD included thick dissection flap, false ...
TTE is most useful in ascending aortic dissections TEE is as sensitive and specific as CT and magnetic resonance imaging (MRI) TEE is strongly dependent on operator experience MRI: The most sensitive method for diagnosing aortic dissection Specificity is similar to that of CT [3] Aorto...
In an attempt to better define criteria for the diagnosis of atherosclerotic aneurysm (AA) and aortic dissection (AD) using CT the scans of 60 documented aortic lesions were reviewed. Hyperdensity of the aortic wall at multiple levels was found to be specific for AD. Central displacement of at...
急性AR可由主动脉夹层(Aortic dissection),主动脉瓣环扩张(Annulo-aortic ectasia)、感染性心内膜炎(Infective endocarditis)或胸部钝性创伤(Blunt trauma to the chest)引起。(表10.3)。 相关检查(Pertinent Investigations) 除了超声心动...

In one case the aortic dissection was made on CT and angiography but was not supported by MR which showed an aortic aneurysm, subsequently confirmed at surgery. Magnetic resonance, CT, and aortography differentiated between type A (nine patients) or B (20 patients) dissection in all cases ...
