Abstract: Objective To investigate the correlation between topographic patterns of different location and vascular lesions and prognosis in patients with pons infarction. Methods 111 patients with pons infarction who were admitted in 2003 were enrolled in this study. All the patients were evaluated using NIHSS, MRS on admission, and were evaluated MRS again on day 30 and day 90 after the onset of the illness. The location and responsible vessel of lesions were evaluated systematically and the multivariate logistic regression analysis of the prognosis at the time of 6 months and the correlative factors were analysed. Results Patients with pons, proximal, and distal territory involvement(OR=6.02, P<0.05), multiple intracranial territory involvement(OR=6.60, P<0.01), in basilar artery acute occlusion(OR=6.10, P<0.001) , were more likely to have the poorest outcome. Conclusion Its found that pons infarction consists of a variety of different stroke topographic patterns and vascular lesions, with various prognosis.
