Clinical differences of ischemic stroke related to lenticulostriate arteries and paramedian pontine arteries caused by intracranial branch atheromatous diseases / 中华神经医学杂志

ABSTRACT

Objective To investigate the clinical differences and the mechanism of ischemic stroke related to intracranial branch atheromatous diseases.Methods All 213 consecutive patients diagnosed with ischemic stroke related to intracranial branch atheromatous diseases by using diffusion-weighted imaging (DWI),admitted to our hospital from January 22,2008 to October 13,2011,were studied.These patients were classified into paramedian pontine arteries group (PPA group,n=56)and lenticulostriate arteries group (LSA group,n=157) according to the DWI findings.The clinical characteristics were compared between the two groups.Results The differences on the mean length of hospital stay and white matter degeneration were statistically significant between PPA group and LSA group (t=-2.044,P=0.045; x2=6.832,P=0.009).In univariate logistic regression analysis,the odds ratio (OR) of concomitant white matter degeneration comparing with the opposite was 11.652,95％CI was (1.483-91.529) and P value was 0.020.Conclusion The ischemic stroke related to intracranial branch atheromatous diseases usually accompanies with concomitant white matter degeneration,and the characteristics are different resulting from different blood supplies.
