摘要
目的评价三维增强MR血管成像(3D CE-MRA)在主动脉瘤诊治中的临床价值。材料与方法 925例主动脉瘤患者行3D CE-MRA检查,工作站上三维重建,探讨图像在制定治疗方案中的作用。结果 925例主动脉瘤中,真性动脉瘤479例(胸段138例,胸腹段29例,腹段312例),主动脉夹层407例(Stanford A型84例,B型232例,主动脉壁内血肿91例),假性动脉瘤39例(胸段21例,腹段18例)。3D CE-MRA立体显示各种动脉瘤类型、形态、部位、病变细节及其与邻近动脉分支的关系,与行腔内隔绝术的DSA比较,3D CE-MRA所测参数与DSA高度一致(P>0.05),对临床治疗方案的制定具有重要指导作用。925例中,352例行腔内隔绝术(真性动脉瘤195例,主动脉夹层126例,假性动脉瘤31例),115例行手术治疗(真性动脉瘤47例,主动脉夹层63例,假性动脉瘤5例)。结论 3D CEMRA能无创、快速、有效诊断主动脉瘤,为手术或腔内隔绝术提供较为全面的信息,可作为主动脉瘤患者,尤其是伴有肾功能不全患者的首选诊断方法。
Objective： To assess the clinical value of three-dimensional dynamic contrast-enhanced MR angiography（3D CE-MRA） in the diagnosis and treatment of aortic aneurysms.Materials and Methods： Nine hundred and twenty five patients underwent 3D CE-MRA with three-dimensional reconstruction on workstation.The clinical role was evaluated for treatment planning.Results： In 925 patients with aortic aneurysms,aortic real aneurysms were 479 cases（thoracic 138,thoracoabdominal 29,and abdominal 312）,aortic dissection 407 cases（Stanford type A 84,type B 232,and intramural hematoma 91）,and aortic pseudoaneurysms 39 cases（thoracic 21,and abdominal 18）.3D CE-MRA clearly demonstrated the type,morphology,location,detail of aortic aneurysm,and 3D relationship with adjacent arteries.The parameters at 3D CE-MRA coincided well with those at DSA in all cases with endovascular graft exclusion（P0.05）.3D CE-MRA was very helpful for surgery and endovascular treatment.Among them,352 cases were perfumed with endovascular graft exclusion（aortic real aneurysms 195,aortic dissection 126,and aortic pseudoaneurysms 31）,115 cases with surgery（aortic real aneurysms 47,aortic dissection 63,and aortic pseudoaneurysms 5）.Conclusions： 3D CE-MRA is a fast,noninvasive and efficient technique in diagnosis and treatment of aortic aneurysms.It can provide reliable information for surgery and endovascular treatment,and could be used as the first choice of patients with renal insufficiency.
