摘要
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.
