MR types study of OCSP in acute young patients with ischemic stroke / 实用放射学杂志

Objective To evaluate the MRI and clinic types of oxfordshire community stroke project(OCSP)in the diagnosis of acute young ischemic stroke patients.Methods 1 64 young patients (18-45 years)and 228 old patients (>60 years)with acute ischemic stroke were analyzed retrospectively.There are four groups according to MR and clinic types of OCSP:total anterior circulation infarct (TACI),partial anterior circulation infarction (PACI),posterior circulation infarction(POCI)and lacunar infarction (LACI).Results Cerebral infarction showed a mild hypo-signal on T1 WI,hyper-signal on T2 WI,FLAIR and DWI.Among the 164 young patients,8 (4.88%)were classified as TACI,72 (43.90%)as PACI,30 (18.29%)as POCI and 54 (32.93%)as LACI.Young and old group image types comparison,χ2 = 1.221,P >0.05.Young stroke patients image and clinical types comparison,Kappa =0.525,P <0.05.Conclusion OCSP imaging types has a good consistency with clinical types,which helps to evaluate ischemic stroke objectively in youth.

Study on the relationship between extracranial carotid arterial stenosis and its severity and OCSP typing of acute cerebral infarction / 中国综合临床

Objective To study the relationship between extracranial carotid arerial stenosis and OCSP typing of acute cerebral infarction. Methods 188 patients with acute cerebral infarction were classified into TACI, PACI, POCI and LACI subtype by OCSP criteria. The lumen diameter, intima-media thickness, plaque, severity of ar-terystenosis of extraeranial carotid arteries in patients with acute cerebral infarction was studied by using HDI-5000 color Doppler ultrasound. Resnlts The prevalence of extracranial carotid arterial stenosis was higher in patients with TACI, POCI subtype than in patients with LACI subtype (X2 = 4.87, P < 0.05 ; X2 = 4.58, P < 0.05). The severity of extracranial carotid arterial stenosis were more prominent in patients with TACI,POCI subtype than in patients with LACI subtype(X2 =7.59,P <0.01 ;X2 =6. 96,P <0.01). Conclusion Extraeranial carotid arterial stenosis and its severity are related to TACI, POCI subtype of OCSP criteria in patients with acute cerebral infarction.

Correlation between modified TOAST classification and OCSP classification in ischemic stroke / 中国实用内科杂志

Objective To study the correlation between 2007 modified TOAST classification and OCSP classification.Methods Totally 177 patients were classified based on the 2007 modified TOAST and OCSP criteria.Analyze whether there was any correlation between the two typing.Results TACI and LACI had significant deviation on distribution of modified TOAST subtype(P
