Objective:To assess the safety and success of the transradial approach and transfemoral approach for diagnostic cerebral arteriography.Methods:We reviewed the medical records of 153 cerebral angiographic studies were performed by use of a transradial and Transfemoral approach between May 2002 and October 2001. Before transradial procedure

we confirmed the collateral blood supply to the hand from the ulnar artery using a modified Allen test;Before transfemoral procedure

we confirmed impulse of femoral artery.after operations

we analysis X-ray exposure time(min)、constrast medium dose、operative procedure time(min)、angei-complications、self-care ability in 24 hours after operations with statistics. Results:The mean time to initial clinical follow-up was 1.5 months.the difference of age、X-ray exposure time、constrast medium dose、operative procedure time is not statistically significant.However

transradial approach is better than transfemoral approach in angei-complications and self-care ability in 24 hours.Conclusion:Compared with transfemoral and transbrachial approaches. transradial approach for selective Cerebral Angiography is safety、efficacy and less invasive for selective cerebral angiography and may warrant consideration as a standard procedure.
