摘要
目的探讨分析假性动脉瘤的多层螺旋CT血管造影(MSCTA)表现及其临床应用价值。方法对16例临床拟诊假性动脉瘤的患者行多层螺旋CT血管造影,获得三维容积数据在图像工作站上以多平面重建(MPVR)、最大强度投影(M IP)和容积再现(VR)等技术进行血管图像重建。结果16例假性动脉瘤MSCTA诊断均被手术(9例)或血管介入治疗(7例)证实。假性动脉瘤发生部位包括颈动脉2例,胸主动脉2例,腹腔脏器动脉5例,髂动脉2例,股动脉5例。16例中9例瘤颈得到清晰显示(56.3%),3例形成动静脉瘘(18.8%),6例对周围组织结构造成压迫推移(37.5%)。结论MSCTA是一项简便、微创而有效的影像检查技术,能够有效显示假性动脉瘤的形态学特征,对临床诊断和治疗有重要价值。
Objective To evaluate the diagnostic performance of muhislice spiral CT angiography (MSCTA) for detection and characterization of pseudo-aneurysms. Methods Sixteen patients with pseudoaneurysms were referred for MSCTA ( 16 of 16). Based on original images, multiple plane volume reconstruction (MPVR) , maxinum intensity projection(MIP) and volume rendering(VR), all images were reconstructed. Results MSCTA was successfully performed in all 16 patients with pseudoaneurysms in different locations( cervix n = 2, thoras n = 2, abdomen n = 5, lower limb n = 7). In terms of detection, the diagnostic accuracy of MSCTA was 100% (16/16). The necks of the pseudoaneurysms were correctly visualized in 56.3% of patients (9/16) on MSCTA. Arteriovenous fistula formation was present in 3 cases (18.8%), and mass effect over adjacent structures was found in 6 cases (37.5%). Conclusion MSCTA is a useful noninvasive technique that can accurately detect and characterize pseudoaneurysms as well as their anatomical relationships to the adjacent structures.
