Abstract:
BACKGROUND: Aortic intramural hemorrhage (IMH), which presents clinical manifestations identical to acute aortic dissection, is suggested to have different pathology and pathophysiology. The purposes of this study were to diagnose IMH by transesophageal echocardiography (TEE) prospectively and to compare clinical and echocardiographic outcome of IMH with those of aortic dissection. METHODS: Between August 1991 and November 1996, 27 IMH and 73 acute aortic dissection were diagnosed using TEE in 202 consecutive patients with suspected aortic dissection. TEE diagnoses of IMH and aortic dissection were initially compared with computed tomography and magnetic resonance imaging and later confirmed by operative findings (n=39) or follow-up changes (n=12). RESULTS: In the 49 patients whose diagnosis was confirmed by operation or follow-up changes, the sensitivity and specificity for the diagnosis of IMH were 27 of 27 (100%) and 20 of 22 (91%), respectively. There were 11 deaths (15%) in acute aortic dissection and 1 death (4%) in IMH during follow-up of 1.7+/-1.5 years (p=NS). Stanford classification and types of treatment were not related to death in both groups. Complications were less frequently noted in IMH (3/27) than in acute aortic dissection (24/73) (p<0.001) and no death occurred in uncomplicated IMH who were medically treated. Follow-up study of 12 IMH patients showed 8 complete resolution, 3 regression, 1 progression. CONCLUSION: TEE is very useful in diagnosis of IMH and IMH has better outcome than the aortic dissection due to absence of communication and intimal tear.
