Objective To introduce the technical improvement for external carotid artery catheterization in rats,and to describe the operation details.Methods We use the inner groove of the dressing forceps to stablize the external carotid artery,incide the blood vessel longitudinally using bistoury,and insert polyethylene catheter into the artery cavity through the oblique cusp,then ligate the suture to fix the catheter.Results The successful rate was higher and the operation time was shorter using the improvement method of the rat carotid artery catheterization.Conclusion The operation is simple when using the dressing forceps fixation of the external carotid artery catheterization,and the special microsurgical instruments are not necessary.
