目的：探讨多层螺旋CT血管成像( MSCTA)检查技术在主动脉夹层( AD)中的临床应用价值。方法回顾分析30例AD患者的MSCTA及数字减影血管造影(DSA)检查资料。结果 MSCTA检查发现AD破口26例(86．67%)及29个破口,破口至LSA根部左缘的距离≥15 mm者21个(72．41%)、<15 mm者8个(27．59%)；DSA检查发现AD破口28例(93．33%)及破口32个,破口至LSA根部左缘的距离≥15 mm者23个(71．88%)、<15 mm者9个(28．12%),差异无统计学意义(P>0．05)。 MSCTA检查显示破口平面主动脉直径(28．55±5．12)mm,DSA检查为(27．70±4．89)mm,差异无统计学意义( P>0．05)。 MSCTA与DSA检查显示夹层累及平面符合程度相似,差异无统计学意义( P>0．05)。MSCTA检查显示夹层假腔内有血栓者22例(73．33%)、动脉壁钙化6例(20．00%),而DSA无法显示夹层血栓及动脉壁钙化情况。结论 MSCTA在显示AD破口、累及范围等方面具有一致性,并且可以显示夹层假腔内血栓及动脉壁钙化,可重复性好,适用于AD的快速筛查、分型及术后随访。

Objective In order to investigate clinical application value of multi-slice spiral CT angiography( MSCTA) in-spection technique for aortic dissection( AD) . Methods Data from MSCTA and digital subtraction angiography( DSA) examination for 30 cases of AD patients were retrospectively analyzed. Results MSCTA examination showed that,26 cases(86. 67%) of pa-tients had AD crevasse,29 cases of patients had crevasse. 21 patients’ (72. 41%) distance from crevasse to left border of LSA (Left subclavian artery)root was not less than 15mm,and 8 patients’(27. 59%)distance from crevasse to left border of LSA root was less than 15mm. DSA examination showed that,28 cases(93. 33%)of patients had AD crevasse,32 cases of patients had cre-vasse. 23 patients’ (71. 88%) distance from crevasse to left border of LSA root was not less than 15mm,and 9 patients’ (28. 12%)distance from crevasse to left border of LSA root was less than 15mm,the differences had no statistical significance ( P>0. 05 ) . Aortic diameter of crevasse plane from MSCTA examination was ( 28. 55 ± 5. 12 ) mm, aortic diameter of crevasse plane from DSA examination was(27. 70 ± 4. 89)mm,the difference had no statistical significance(P>0. 05). Compliance degree of dissection involving plane from MSCTA examination was similar with data from DSA exaination,the difference had no statistical significance(P>0. 05). MSCTA examination showed that 22 cases(73. 33%)of patients had thrombus in dissection false lumens, 6 cases(20. 00%)of patients suffered from arterial wall calcification,DSA examination can not detect conditions of thrombus in dissection false lumens and arterial wall calcification. Conclusion MSCTA examination can accurately detect AD crevasse,dis-section involving scope and so on. Moreover,it can detect conditions of thrombus in dissection false lumens and arterial wall calci-fication. The method had good repeatability,so it is suitable for fast screening of AD,typing and postoperative follow-up.
