摘要

本文对31例主动脉夹层患者进行了磁共振成像(MRI)检查,以评价其在诊断真、假腔间连通口位置和是否存在逆行夹层中的价值。MRI显示,15例患者中有12例(80%)的图像显示进入部位为内膜皮瓣缺损。8例患者中有6例(75%)可以确定腹主动脉真腔和假腔之间的连通口的位置。3例逆行性夹层MRI诊断成功。根据真管腔位置对腹主动脉进行横断面分析发现,当真管腔位于腹主动脉前部时,腹腔动脉和肠系膜上动脉往往发源于真管腔。当真腔位于前外侧时,左、右肾动脉起源于真腔。综上所述,MRI是主动脉夹层的有效诊断方法,尤其是确定胸主动脉的入口位置。假腔内信号强度的变化为定位真腔和假腔之间的连通口和诊断逆行性夹层提供了有用的信息。腹主动脉解剖的横断面分析有助于预测主动脉从真腔或假腔的分支。

[Magnetic resonance diagnosis of aortic dissection: with special reference to the communicating orifice between the true and false lumens].

Magnetic resonance imaging (MRI) was performed in thirty-one patients with aortic dissection to evaluate its usefulness in diagnosing the site of communicating orifice between the true and false lumens and the presence of retrograde dissection. MRI revealed the site of the entry as a defect in the intimal flap in the images of 12 of 15 patients (80%). The site of the communicating orifice between the true and false lumens in the abdominal aorta could be determined in six of eight patients (75%). MRI diagnosis of retrograde dissection was successful in three patients. Cross-sectional analysis of the abdominal aorta based on the location of the true lumen revealed that the celiac and superior mesenteric arteries tended to arise from the true lumen when the latter was situated in the anterior part of the abdominal aorta. The right and left renal arteries arose from the true lumen when it was positioned anterolaterally. In conclusion, MRI was a useful diagnostic method for aortic dissection, especially for determining the site of entry in the thoracic aorta. The changes in signal intensity in the false lumen provided useful information for locating the communicating orifice between the true and false lumens and for diagnosis of retrograde dissection. Cross-sectional analysis of dissection in the abdominal aorta was useful for predicting the branching of the main arteries from the true or false lumen.
