Abstract:
Objective To observe the feasibility and security of the embolization with medical adhesive on renal artery in rab‐bits by animal experiments ,and explore the effectiveness of different concentration of embolic agents on the process and the effect of embolization for vascular ,and provide guidance for clinical application of medical adhesive .Methods A mixture of different ratios of lipiodol and medical adhesive were used to embolize the renal artery in 18 rabbits ,the usage and effects of embolization were ob‐served .Results Embolic agents were seen under the fluoroscopy ,easy to control and inject transcatheter ,also repeated injected by one micro‐catheter safety and effectively .Angiography review showed a reliable embolization ,no vascular recanalization and no spill‐over of contrast agent .Optical microscope ,after HE staining in postoperative pathological examination ,showed irregular shaped embolic agents or branch like refractive index of transparent material in the embolized artery .In 5∶1 group and 4∶1 group ,arteri‐ole and small artery were mainly embolized ,there was no significant difference between the two groups(P>0 .05);Whereas medium sized artery was mainly embolized in 3∶1 group ,compared with the 5∶1 group and 4∶1 group ,the differences was statistically significant(P<0 .05) .After operation ,renal function was transient damage ,leukocyte was transient increasing ,one week later ,both of renal function and leukocyte were recovered ,and there was no significantly renal function anomaly .Conclusion It is feasible ,safe and effective for medical adhesive to embolize rabbits renal artery ,the different concentration of the embolic agents can embolize the different branches of rabbit renal artery .
