64排螺旋CT血管造影对主动脉夹层的诊断价值研究

Diagnostic Value of 64 slice spiral CT Angiography in Aortic Dissection

目的探讨64排螺旋CT血管造影对主动脉夹层的诊断价值进行探讨和分析。方法对2010年3月至2012年12月期间我院使用64排螺旋CT治疗的50例主动脉夹层患者临床资料进行回顾性分析总结。结果根据Debakay分类标准,在50例主动脉夹层患者中,Ⅰ型患者为15例,Ⅱ型患者为11例,Ⅲ型患者为24例。所有患者都可以清晰看到清晰破口、真假双腔以及低密度线样内膜瓣影,假腔直径最大为47mm,真腔直径最小为5mm,有21例患者可以看到在假腔内有附壁血栓形成。此外,在50例主动脉夹层患者中,有5例患者动脉夹层累及头臂干,4例患者累及左锁骨下动脉,6例患者累及腹腔干,5例患者累及肠系膜上动脉,14例患者累及髂总动脉及其分支。结论 64排螺旋CT血管造影对主动脉夹层的评价具有较高的准确性,可作为诊断筛查疑似主动脉夹层的一种首选影像诊断方法。

Objective To investigate the value of 64 Multi-Slice Spiral CT angiography in the diagnosis of aortic dissection and analyze. Methods During the period from 2010 March to 2012 December in our hospital 64 row helical CT in treatment of 50 cases of aortic dissection in patients with clinical data were retrospectively analyzed and summarized. Results According to Debakay classification, 50 patients with aortic dissection, 15 cases of type I patients, patients with type II 11 cases, type III patients of 24 cases. All patients can clearly see clear break, true and false cavity and low density linear intimal flap, false lumen diameter is 47ram, the true lumen diameter minimum 5ram, 21 patients can see the mural thrombus in the false lumen. In addition, in 50 patients with aortic dissection, 5 patients with aortic dissection involving the brachiocephalic trunk, 4 cases involving the left subclavian artery, 6 cases involving the celiac trunk, 5 patients with superior mesenteric artery, 14 cases involving the common iliac artery and its branches. Conclusion Evaluation of aortic dissection 64 row helical CT angiography has high accuracy, a preferred imaging method can be used as a diagnostic screening suspected aortic dissection.
