目的 探讨多层螺旋CT血管造影(MSCTA)及其三维重建在主动脉夹层动脉瘤的CT表现及诊断价值.方法 收集72例行主动脉64排螺旋CT增强扫描的主动脉夹层动脉瘤患者的临床资料,将MSCTA原始数据在ADW4.4工作站进行最大密度投影、多平面重建、曲面重建、容积再现的主动脉血管重建处理,并将获取的资料进行综合分析,完成诊断.结果 全部病例均很好地显示了主动脉全程及其主要分支血管,清晰地显示夹层动脉瘤的部位、范围、真腔、假腔、内膜片等,其中主动脉壁增厚钙化51例及附壁血栓39例也清晰显示.6例主动脉夹层患者经内支架置入术后复查,其支架位置、形态、膨胀程度及真假腔情况也得到满意显示.结论 MSCTA可清晰地显示主动脉夹层及主要分支血管的改变,为临床选择合理的治疗提供有价值的依据,是诊断夹层动脉瘤有效的检查方法,具有较高的临床应用价值.
目的 探討多層螺鏇CT血管造影(MSCTA)及其三維重建在主動脈夾層動脈瘤的CT錶現及診斷價值.方法 收集72例行主動脈64排螺鏇CT增彊掃描的主動脈夾層動脈瘤患者的臨床資料,將MSCTA原始數據在ADW4.4工作站進行最大密度投影、多平麵重建、麯麵重建、容積再現的主動脈血管重建處理,併將穫取的資料進行綜閤分析,完成診斷.結果 全部病例均很好地顯示瞭主動脈全程及其主要分支血管,清晰地顯示夾層動脈瘤的部位、範圍、真腔、假腔、內膜片等,其中主動脈壁增厚鈣化51例及附壁血栓39例也清晰顯示.6例主動脈夾層患者經內支架置入術後複查,其支架位置、形態、膨脹程度及真假腔情況也得到滿意顯示.結論 MSCTA可清晰地顯示主動脈夾層及主要分支血管的改變,為臨床選擇閤理的治療提供有價值的依據,是診斷夾層動脈瘤有效的檢查方法,具有較高的臨床應用價值.

Objective To investigate the CT Manifestations andi diagnostic value of multislice spiral CT angiography (MSCTA) and its 3D-restruction in dissecting aneurysm of aorta.Methods 64-slice spiral CT enhancing scan of dissecting aneurysm of aorta was performed in 72 patients,and the data was transferred to ADW4.4 workstation for aortic vascular reconstruction image post processing including the maximum density projection (MIP),multiple planar reconstruction (MPR),curved planar reconstruction (CPR) and volume rendering (VR),the data of MSCTA were done and analyzed.Results The whole aorta and branches in 72 patients were displayed well by MSCTA.The location,extend,true lumen,false lumen and intimal flap of dissecting aneurysm were showed in all patients satisfactorily.In the 72 cases,thickening and calcification of the aortic wall were 51cases,intraluminal thrombus were 39cases.The results of postoperative review in 6 cases of patients with aortic stent placement dissection revealed that the location and shape of stent,the dilatation degree,the true and false lumen were also displayed satisfactorily.Conclusions MSCTA can clearly display the aortic dissecting aneutysm and its branches,and is a valuable tool in the assessment and diagnosis of aortic dissections,it has important clinical application value.
