摘要
目的讨论16层螺旋CT血管造影在腹主动脉瘤诊断中的应用价值。方法20例腹主动脉瘤患者行16层螺旋CT血管造影(15例DSA证实,5例手术证实),采用多平面重组(multiplanar reformation,MPR)、最大密度投影(maximal intensity projevtion,MIP)、容积再现(volume rendering,VR)。结果20例中肾下型16例,近肾型2例,肾上型2例。瘤体近端最大瘤径8-57mm,最小瘤径6-15mm;最大直径55-75mm,最小直径31-38mm,瘤体最长118mm。15例伴瘤体内附壁血栓(1例合并主动脉夹层,2例合并髂总动脉瘤),其中囊状扩张4例,梭状扩张11例,囊梭状混合型5例;真性动脉瘤19例,假性动脉瘤1例。结论MSCTA可以快速、准确、无创诊断腹主动脉瘤,是最理想的检查方法之一。
Objective To explore the diagnostic value of abdominal aortic aneurysm （AAA） withl6 - slice spiral CT. Methods Twenty patients with AAA were examined with 16 slice spiral CT. Multiplanar reformation （ MPR）, maximal intensity projection （MIP） and volume rendering （VR）. Results Enter here the need for translation of which 16 cases of renal - type （ 80% ）, two cases of near Nephropathogenic （ 10% ）, and the type 2 cases of renal （ 10% ）. Tumor proximal largest tumor diameter 8mm -57mm, the smallest tumor diameter 6mm -15mm. Tumor maximum diameter of 55mm -75mm. Minimum diameter31mm -38mm. Tumor longest llSmm. 15 patients with tumors containing a mural thrombus, in which example 1 with aortic dissection, the two examples combined iliac aneurysms. Of which four cases of cystic dilatation, 11 cases of Clostridium expansion, capsule mixed five cases of Clostridium, 19 cases of true aneurysm, pseudoaneurysm in 1 case. MPR can show good tumor cavity containing the scope of mural thrombus. MIP showed calcification of aneurysm wall the best. Conclusion MSCTA can be rapid, accurate, and non - invasive diagnosis of abdominal aortic aneurysm, Abdominal aortic aneurysm is increasingly becoming the diagnosis, postoperative follow - up of the best method of examination.
