摘要
目的探讨多层螺旋CT血管造影(MSCTA)在诊断内脏动脉瘤中的临床价值。方法回顾性分析42例内脏动脉瘤患者的CT增强扫描资料,采用容积重组(VR)"血管生长"技术(AV)、多平面重建(MPR)行血管重建。结果 42例患者中,共发现58个动脉瘤,均清晰显示动脉瘤与载瘤动脉的关系,其中脾动脉瘤27个(46.6%),肝动脉瘤6个(10.3%),肾动脉瘤10个(17.2%),肠系膜动脉瘤7个(12.1%),腹腔动脉瘤8个(13.8%),3个破裂(5.2%),8个合并显示载瘤动脉狭窄(13.8%)。结论 MSCTA能准确诊断内脏动脉瘤及伴发或继发性改变。
Objective To evaluate the diagnostic value of multi-slice spiral CT angiography （MSCTA） in visceral aneurysm. Methods Unenhanced and contrast-enhanced CT scans in 42 cases of visceral aneurysm were retrospectively analyzed. Volume rendering and multiplanar reconstruction were performed to reconstruct the vascular images. Results The relationship between parent arteries and 58 aneurysms found in 42 patients were displayed clearly. The aneurysms arose from the splenic artery （27, 46.6%）, hepatic artery （6, 10.3%）, renal artery （10, 17.2%）, mesenteric artery （7, 12.1%）, celiac artery （8, 13. 8%）. Three of the aneurysms were ruptured （5.2%） and 8 were associated with parent artery stenosis （13.8%）. Conclusion MSCTA clearly depict visceral aneurysm and complications.
