ABSTRACT
Objective To investigate the prevalence and severity of cerebral microbleeds (CMBs) in patients with different stroke classifications of cerebral infarction.Methods From October 2016 to December 2017,the clinical data of patients with acute cerebral infarction in the Second Affiliated Hospital of Xuzhou Medical University were collected through the prospective study.The SWI technique was used to screen the CMBs.According to the TOAST and OCSP classifications, the prevalence and severity of CMBs in patients with different stroke classifications of cerebral infarction were analyzed.Results A total of 254 patients with cerebral infarction were enrolled ,there were 136 patients(53.54%) in CMBs group and 118 patients(46.46%) in no CMBs group.The prevalence of CMBs in patients with different TOAST classifications was large artery atherosclerosis ( 54.29%), small -artery occlusion (64.15%), cardioembolism (40.43%), stroke of other determined etiology ( 33.33%), stroke of undetermined etiology(38.46%),and the difference was statistically significant (χ2 =12.206,P=0.016).The prevalence of CMBs in patients with different OCSP classifications was total anterior circulation infarcts ( 43.75%), partial anterior circulation infarcts ( 51.19%), posterior circulation infarcts ( 49.18%), lacunar infarcts ( 67.53%), and the difference was statistically significant(χ2 =8.944,P=0.030).The severity of CMBs in patients with different TOAST classifications was large artery atherosclerosis [mild(55.26%),moderate(26.32%),severe(15.79%)],small-artery occlusion[mild(25.00%),moderate (33.82%), severe (41.18%)], cardioembolism [ mild (57.89%), moderate (26.32%),severe(15.79%)),stroke of other determined etiology [ mild(50.00%),moderate (33.33%),severe (16.67%)],stroke of undetermined etiology [ mild(60.00%),moderate (20.00%),severe (20.00%)],and the difference was statistically significant (Fisher exact test,P=0.025).The severity of CMBs in patients with different OCSP classifications was total anterior circulation infarcts [mild(57.14%),moderate(28.57%),severe(14.29%)], partial anterior circulation infarcts [ mild (52.50%), moderate (32.50%), severe (15.00%)], posterior circulation infarcts[mild( 50.00%), moderate (33.33%), severe (16.67%)], lacunar infarcts [ mild (25.00%), moderate (32.69%),severe (42.31%)], and the difference was statistically significant ( Fisher exact test, P =0.023 ). Conclusion The prevalence and severity of CMBs in patients with different stroke classifications of cerebral infarction are variable.The prevalence of CMBs in small -artery occlusion and lacunar infarcts are the highest and give first place to severe CMBs (number of lesions≥10).We should pay attention to these two stroke classifications by early recognition and taking targeted clinical strategies.
