摘　　要：目的：探讨多层螺旋CT血管成像（MSCTA）对主动脉夹层的诊断及术后随访的价值。方法：对46例主动脉夹层（其中11例有术前及术后对照）患者进行了MSCTA胸腹联合检查，将原始数据初步重建后传到工作站进行多平面重建（MPR）、最大密度投影（MIP）及容积再现（VR）等后处理。结果：46例均满意地显示了主动脉夹层的部位和范围，真腔、假腔、内膜片及撕裂口均能得到清楚显示；11例术后显示管腔复张及支架位置良好，4例再发其他部位夹层。结论：MSCTA对主动脉夹层的术前诊断及术后随访均具有较高的临床应用价值，可作为诊断主动脉夹层的首选检查方法。Objective To investigate the diagnostic and postoperative follow-up survey value of muhislice spiral CT angiography（MSCTA） for aortic dissections. Methods MSCTA study was performed in 46 patients with aortic dissections, in which 11 cases were contrasted by preoperative and postoperative data. After primary reconstruction in scanstation, the volume data was transferred to workstation for image post-processing including MPR, MIP and VR. Results The location and extend of aortic dissections in 46 patients were demonstrated well by MSCTA, and the truelumen, falselumen, intimalflap and chasm were showed satisfactorily in all patients. To the postoperative group, the aortic diastole and the location of stands of the 11 patients were showed in good condition. However, recrudescence of aortic dissections were oberserved in other location of 4 patients. Conclusion MSCTA has highly clinic value for the diagnosis of aortic dissections and the postoperative follow-up survey. Therefor, it can be used as the preferred mothed for this disease.
