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.
