Intramural Hemorrhage of the Thoracic Aorta Diagnostic and Therapeutic Implications

摘要: Background Intramural hemorrhage (IMH) was recently identified at necropsy and anecdotally in vivo as a unique aortic syndrome (without entry with no flap-like intraluminal component, such overt dissection). However, little is known about diagnosis, prognosis, outcome of IMH.

Among 195 syndromes, 25 (12.8%) diagnosed have IMH thoracic aorta evidence primary intimal tear, flap, by multiple noninvasive imaging modalities, including magnetic resonance (n=12), contrast-enhanced computed tomography (n=14), transesophageal echocardiography (n=3) random order.
