摘要： 目的探讨64层螺旋CT三维重建技术在主动脉夹层介入术前评估中的价值。方法选择2023年7月—2024年5月在潜江市中心医院诊治的主动脉夹层疑似患者96例为研究对象,所有患者均进行64层螺旋CT三维重建技术检查,记录成像参数。所有患者在64层螺旋CT三维重建后进行介入治疗,以介入检查结果为金标准,判断64层螺旋CT三维重建技术在主动脉夹层介入术前评估中的价值。结果在96例患者中,64层螺旋CT三维重建联合判断为主动脉夹层60例,其中Ⅰ型32例、Ⅱ型20例、Ⅲ型8例,其中再现（VR）、最大密度投影（MIP）及多平面重建（MPR）分别判断为主动脉夹层56例、54例、56例。在96例患者中,64层螺旋CT三维重建检查的破口层面主动脉平均直径（3.08±0.25）cm、破口至左锁骨下平均距离（4.05±0.26）cm,与介入治疗检查（3.05±0.36）cm、（4.06±0.14）cm,对比差异无统计学意义（t=0.671,P=0.503;t=0.332,P=0.740）。64层螺旋CT三维重建联合、VR、MIP、MPR对主动脉夹层的诊断灵敏度分别为98.33%、93.22%、89.83%、94.92%,特异度分别为97.30%、97.30%、97.30%、100.00%,准确率分别为98.96%、94.79%、92.71%、96.88%。结论 64层螺旋CT三维重建技术在主动脉夹层介入术前评估中具有很高的灵敏度、特异度与准确率。

Abstract: Objective To explore and analyze the value of 64-slice spiral CT three-dimensional reconstruction technology in the preoperative assessment of aortic dissection（AD）intervention．Methods From July 2023 to May 2024,96 cases of patients suspected of aortic dissection treated in our hospital were selected as the research subjects．All patients underwent 64-slice spiral CT three-dimensional reconstruction technology examination,and imaging parameters were recorded．After the 64-slice spiral CT three-dimensional reconstruction,all patients were given interventional treatment,and the results of the interventional examination were used as the “gold standard” to evaluate the value of 64-slice spiral CT three-dimensional reconstruction technology in the preoperative assessment of aortic dissection intervention．Results Among the 96 patients,64-slice spiral CT three-dimensional reconstruction combined diagnosis identified 60 cases of aortic dissection,including 32 type I,20 type II,and 8 type III cases．volume rendering（VR）,maximum intensity projection（MIP）,and muhiplanar reconstrudion（MPR） identified 56,54,and 56 cases of aortic dissection,respectively．In 96 patients,the mean aortic diameter at the lacerated level and the mean distance from the lacerated to the left subclavicular level were（3.08±0.25）cm and（4.05±0.26）cm respectively in 64-slice spiral CT three-dimensional reconstruction examination,compared with（3.05±0.36）cm and（4.06±0.14）cm in interventional examination．There was no difference in comparison（t=0.671,P=0.503;t=0.332,P=0.740）．The sensitivity,specificity,and accuracy of the 64-slice spiral CT three-dimensional reconstruction combined,VR,MIP,and MPR for the diagnosis of aortic dissection were 98.33%,93.22%,89.83%,94.92%,specificity were 97.30%,97.30%,97.30%,100%,accuracy were 98.96%, 94.79%,92.71%,96.88%．Conclusions Technology of 64-slice spiral CT three-dimensional reconstruction has high sensitivity,specificity,and accuracy in the preoperative assessment of aortic dissection intervention and is worth promoting and applying clinically．
