主动脉壁内血肿的多层面螺旋CT诊断研究(1)
摘要: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。

Abstract: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

主动脉夹层在临床当中属于一种急性主动脉综合征,其中主动脉壁血肿属于其一种变异类型,其危险性以及致死率非常高。根据相关实践研究表明[1],其相关症状与主动脉夹层非常相似,可是主动脉壁当中血肿在病理以及影像上与其有所不同。目前,CT、磁共振以及TEE(经食道超声)都能够作为诊断主动脉壁内血肿的非创影像手段,特别多层面螺旋CT的发展,应用范围以及薄层扫描成为可能,对主动脉壁内血肿的诊断以及病变范围的判断具有重要意义[2]。本研究做了相关探讨,现报道如下。
1 资料与方法
1.1一般资料 对2014年3月~2016年3月在我院高度疑似主动脉病理变化的患者一共有46例,当中男38例,女8例。年龄在38~76岁,平均为(50.3±2.8)岁。
1.2方法 采取美国GE公司生产的LightSpeed64多层面螺旋CT扫描机,电压为120kV,110~250mAs,层厚1.25mm,重建间隔1mm,pitch为1.75:1,床进速为35mm/r。采取高压注射器将100ml非离子造影剂通过手背静脉或者肘部静脉注入,延迟20~25s以后进行扫描和胸腹主动脉联合扫描。横轴位图像在工作站给予后处理重建,得到MPR(多平面重建)、CPR(曲面重建)、MIP(最大密度投影)以及VR(容积再现)图像。
1.3临床诊断标准 主动脉壁内血肿平扫为同心圆型或者新月型高密度主动脉壁增厚;增强扫描主动脉腔内没有明确的内膜片显示,不增强的主动脉壁增厚在5mm以上。IMH的分型与主动脉夹层相同,累及升主动脉为A型,不累及升主动脉为B型。主动脉穿透性溃疡增强扫描表现为增厚的主动脉壁内部有造影剂充盈的龛影[3]。, 百拇医药(李小兰)
