ObjectiveTo compare the effect of salt bag compression and arterial compressor haemostat for patients after cerebral angiography.Methods Four hundred and ninety-five patients undergoing cerebral angiography were divided into two groups according to the methods of arterial compression:salt bag compression group (243 cases) and arterial compressor haemostat group (252 cases) in which 131 patients used the YM-GU-1229 arterial compressor haemostat and 121 patients used the NZ-1 arterial compressor haemostat.The associated complications within 3 days were recorded.ResultsThe incidence of complications in salt bag compression group was 3.70％(9/243),in arterial compressor haemostat group was 9.92％ (25/252),and there was significant difference between the two groups(P ＜ 0.01 ).The incidence of complications in YM-GU-1229 arterial compressor haemostat was 12.21％ ( 16/131 ),in NZ-1 arterial compressor haemostat was 7.44％(9/121 ),and there was no significant difference between the two arterial compressor haemostats (P ＞ 0.05).ConclusionThe incidence of complications of arterial compressor haemostat is higher than that of salt bag compression.
