64排(多层)螺旋CT血管成像在主动脉夹层累及动脉分支的机理及动力学探讨

64 Rows (multi-layer) of Spiral CT Angiography in Aortic Dissection Involving the Arterial branch and Its Kinetics and Mechanism StudyAortic Dissection Involving the Arterial Branches

目的探讨64排多层螺旋CT血管成像技术在主动脉夹层累及主动脉分支机理。方法选取我院CT检查典型主动脉夹层共38例,观察AD分型、主动脉受累分支及破口情况;结果 38例AD患者中,A型22例,B型16例;主动脉累及分支111支,其中完全来源于假腔70支,完全来源于真、假腔40支;显示内膜破口40个;结论主动脉受累分支与内膜破口表现出相关性,可能与脉动血压有关。

Objective Discussion of 64 Multi-Slice Spiral CT angiography in aortic dissec- tion involving the aortic bifurcation of mechanism. Method Select our hospital CT examina- tion of classic aortic dissection of 38 cases, observation of the AD typing, aortic branches involvement and crevasse situation. Result In 38 AD patients,22 cases of type A, type B in 16 cases： aortic involvement of branchl 11, which is derived entirely from the false lumen70, is derived entirely from the true, false lumen showed intimal40：40 show the intimal tear. Conclusion Aorta branch and intimal demonstrate the relevance, may be associated with pulsatile blood pressure related,
