摘要
目的探讨多层螺旋CT动脉成像对骨盆骨折动脉损伤的诊断价值。方法对25例骨盆骨折患者行多层螺旋CT动脉造影(M SCTA)检查,将图像在工作站上用容积重建(VR)、最大密度投影(M IP)及多平面图像重建(M PR)进行后处理,分析骨折周围的血管走行和损伤情况。结果扫描图像双侧髂总动脉,双侧髂内髂外动脉及其分支均显示清晰,轴位及多种方法重建后见32处骨折周围血肿内中小动脉旁造影剂漏出影,1例髂内动脉截断影,均经手术证实。结论多层螺旋CT血管造影能较好显示骨盆骨折后骨盆血管的损伤情况,对骨折造成的动脉损伤具有很高的诊断价值;缺点是费用较高。
[Objective] To evaluate the diagnostic value of multi-slice spiral CTA in pelvic arterial injuries with pelvic fractures. [Methods] 25 patients with pelvic fractures were examined with MSCTA. The raw data was performed with VR.MIP and MPR in workstation. We analyzed the CTA images to find the injured arterials around pelvic fractures. [Results] In the axial and reconstruction images, we can observe the iliac arterial branches clearly. We can find the extravasation of contrast material within a hematoma around 32 fracture sites and one internal iliac arterial truncated. All of the results were proved by operation. [Conclusions] MSCTA is valuable for diagnosis of injured arterial around the pelvic fracture.
