目的分析研究主动脉壁内血肿采取多层面螺旋CT诊断的临床应用价值。方法对在我院高度疑似主动脉病理变化的患者一共有46例，对46例患者采取多层面螺旋CT扫描，同时诊断为主动脉壁内血肿。2名有丰富临床经验的放射科医师根据CT标准给予诊断，采取64排多层面螺旋CT获得1.25mm层厚图像。结果46例患者主动脉壁内血肿当中，A型一共有2例，B型一共有44例；B型壁当中血肿，但是累及降主动脉的16例，胸腹主动脉受累22例，局限在腹主动脉一共有6例；22例壁内血肿伴有主动脉穿透溃疡，当中4例进行带膜内支架治疗。结论对主动脉壁内血肿采取多层面螺旋CT进行诊断，可以使临床诊断准确率明显提高，为制定临床治疗方案提供重要依据，具有临床推广价值。“,”Objective To study the clinical application value of multi slice spiral CT in the diagnosis of aortic wall hematoma.Methods A total of 46 patients with suspected aortic pathological changes in our hospital,46 cases of patients with multi slice spiral CT scan,while the diagnosis of aortic wall hematoma.A rich clinical experience of the radiologists according to standard CT gives the diagnosis and 1.25 mm slice thickness images obtained by 64 row multi slice helical CT.Results 46 cases of patients with aortic wall hematoma,a type of a total of 2 cases,type B a total of 44 cases;B type wall hematoma,but involvement of the descending aorta in 16 cases,22 cases of thoracic and abdominal aorta were involved in limited in the abdominal aorta,a total of 6 cases;22 cases of intramural hematoma with associated penetrating aortic ulcer,4 cases were with metallic stents in the treatment of membrane.Conclusion The diagnosis of aortic wall hematoma by multi slice spiral CT can significantly improve the accuracy of clinical diagnosis and provide an important basis for the development of clinical treatment programs.
