【摘要】 目的 评价多层螺旋CT血管成像(MSCTA)在体部动脉性病变诊治中的应用价值。方法 68例经手术病理证实的体部动脉病变患者行MSCTA检查,其中颈部35例,胸腹主动脉及其分支23例,双下肢动脉10例。应用多平面重建(MPR),曲面重建(CPR),最大密度投影(MIP),容积显示技术(VRT)以及血管分析(VA)软件进行图像重建及分析。结果 68例体部动脉病变中,CTA显示颈动脉钙化斑块伴狭窄25例,颈内动脉闭塞1例,颈总动脉假性动脉瘤1例,颈动脉鞘内神经源性肿瘤伴血管推移2例,椎动脉钙化狭窄5例,椎动脉瘤1例。胸、腹主动脉瘤5例,假性动脉瘤8例,主动脉夹层10例,双下肢动脉硬化性闭塞症9例及下肢血管动静脉瘘1例。结论 多层螺旋CT血管成像对体部动脉病变的临床诊治具有重要指导意义。更多还原

【Abstract】 Objective To evaluate the value of multislice spiral CT angiogrpahy(MSCTA) in diagnosis of arterial diseases in body.Methods MSCTA was performed in 68 patients with artery diseases proved by surgery-pathology,including neck in 35 cases,thoracic and abdominal aorta and it’s main branches in 23 cases and bilateral lower extremity artery in 10 cases.The lesions of arteriae were analysed with reconstructed images including MPR,CPR,MIP,VRT and VA.Results MSCTA demonstrated carotid artery calcification with stenosis in 25 cases,internal carotid artery occlusion in 1 case,false aneurysm of common carotid artery in 1case,neurogenic tumor of carotid sheath in 2 cases,vertebral artery calcification with stenosis in 5 cases,vertebral artery aneurysm in1 case,aneurysm of thoracic and abdominal artery in 5 cases,false aneurysm of thoracic and abdominal artery in 8 cases,dissection of thoracic and abdominal aorta in 10 cases,arteriosclerosis obliterans bilateral lower extremities in 9 cases and arteriovenous fistula of bilateral lower extremities vessels in 1 case.Conclusion MSCTA examination is of significant value in diagnosing artery lesions of body.更多还原
