| 目的探讨创伤性动脉瘤(PA)、动静脉瘘(tAVF)在CDFI、CTA、MRA、DSA表现上的特点。方法 用显微外科技术在40只新西兰白兔股部建立PA、tAVF模型,模型建成后行CDFI、CTA、MRA及DSA检测。结果 在20个手术部位建成16个PA模型,在30个手术部位建成26个tAVF模型,成功率分别为80％和87％,模型在CDFI、CTA、MRA、DSA上的表现各具特点。结论 显微外科技术建立兔股部PA,tAVF模型,方法切实可行;在各检测手段上,其表现各具特点,互相补充,根据需要选用,可提高诊断治疗水平。 |

| Objective To explore the possibility of establishment of experimental femoral pseudoaneurysm (PA) and traumatic arteriovenous fistula (tAVF) models in 40 rabbits and its related study. Methods Experimental PA and tAVF models were established in rabbit with microsurgical anastomosis technique. Models were checked by color Doppler flow imaging (CDFI), examined by computed tomography angiography (CTA), magnetic resonance angiography (MRA) and digital subtraction angiography (DSA). Results Sixteen femoral PA in 20 rabbits (80%) and 26 tAVF in 30 rabbits (87%) were successfully anastomosed and were confirmed by related examination methods. Conclusion It is possible to establish PA and tAVF experimental models in rabbits with microsurgical technique and each one of the above examination methods has its own characteristics. A combination of these examination methods may improve the diagnostic accuracy and treatment ability clinically. |
