腹主动脉瘤超声造影表现与CT血管成像的比较

The value of contrast-enhanced ultrasonography in evaluating abdominal aneurysm and comparison by CT angiography

目的比较腹主动脉瘤超声造影与CT血管成像(CTA)的表现,探讨超声造影(CEUS)在腹主动脉瘤诊断及术后随访中的应用价值。方法采用超声造影检查对18例(术前检查10例,术后复查8例)腹主动脉瘤患者进行术前诊断或术后复查,所有患者均同时行CT血管成像检查。将两种方法诊断术前患者真性动脉瘤、夹层动脉瘤、假性动脉瘤及术后有无内漏情况进行对比研究。结果术前超声造影诊断为真性动脉瘤5例,夹层动脉瘤4例,假性动脉瘤1例;术后随访8例中支架置入及人工血管置换各4例,均未见内漏,与CTA结果一致。结论应用超声造影对腹主动脉瘤进行术前诊断及术后随访,结果和CTA一致,值得推广应用。

Objective To compare the capability of contrast-enhanced ultrasonograpby （CEUS） and CT angiography （CTA）in evaluating abdominal aortic aneurysm. Methods Both CEUS and CTA examinations were performed in 18 patients （diagnosis before surgery in l0 patients, surveillance after sur- gery in 8 patients）. The CEUS contrast agent was Sonovue. The diagnosis and the appearance about abdominal aortic aneurysm, dissecting aortic aneurysm, aortic pseudoaneurysm and the image after operation were compared. Results There were abdominal aortic aneurysm in 5 patients, dissecting aortic aneurysm in 4 patients and aortic pseudoaneurysm without operation in 1 patient. The 8 patients under surveillance after operation including endovascular abdominal aortic aneurysm repair in 4 patients and open repair with artificial vascular in 4 patients. Both CEUS and CTA had the same results. Conclusion The CEUS is comparable to CTA in diagnosing abdominal aortic aneurysm. The CEUS is worthy of application in abdominal aortic aneurysm.
