Thirteen patients, aged 3-31 years, with coarctation of the thoracic aorta were examined by magnetic resonance (MR) imaging (total of 14 studies). Eight studies were performed preoperatively and six postoperatively. Catheterization data were available on 12 patients for verification of MR imaging findings. Electrocardiographically gated sagittal and left anterior oblique images best depicted the coarctations; however, involvement of arch vessels was best evaluated on transaxial images. MR imaging readily identified all coarctations but one, their site and extent, and involvement of the arch vessels. In addition, MR images depicted poststenotic dilatation and dilated collateral vessels. In patients studied postoperatively, restenosis could be evaluated, and complications such as postoperative aneurysm and perianastomotic hematoma were identified. MR imaging provides excellent anatomic detail of coarctation of the aorta, potentially obviating the need for angiography.
13例年龄在3至31岁之间的胸主动脉缩窄患者接受了磁共振(MR)成像检查(共14次研究)。8次研究在术前进行,6次在术后进行。12例患者有导管检查数据,用于验证MR成像结果。心电门控矢状位和左前斜位图像能最佳显示缩窄情况;然而,弓部血管受累情况在横轴位图像上评估最佳。MR成像除1例缩窄外,能轻易识别所有缩窄及其部位和范围,以及弓部血管受累情况。此外,MR图像还能显示缩窄后扩张和扩张的侧支血管。对术后研究的患者,可评估再狭窄情况,并识别术后动脉瘤和吻合口周围血肿等并发症。MR成像能提供主动脉缩窄出色的解剖细节,可能无需进行血管造影。
