Abstract: 【Abstract】Objective: To Study the correlation between lesions of deglutition center and acute Cerebral Infarction by OCSP classification of stroke. Methods: The clinical data of 848 patients into groups in order with acute cerebral were retrospectively analyzed. Cerebral infarction by OCSP classification of stroke were divided into the following 4 groups: TACI for the whole anterior circulation infarction, PACI for the partial anterior circulation infarction,POCI for the posterior circulation infarction and LACI for the lacunar infarction. Cerebral infarction by water swallow test were divided into the following 2 groups: dysphagia and non- dysphagia. Data related were collected and analyzed through statistics. Results: Dysphagia incidence of acute Cerebral Infarction by OCSP classification of stroke were significantly different(P＜0.05). Dysphagia incidence on TACI 、POCI –type and PACI 、LACI-type were significantly different(P＜0.05). Dysphagia incidence on TACI 、PACI 、LACI-type and brain of One-tailed or Double side were significantly different(P＜0.05). Dysphagia incidence on POCI-type and brain of One-tailed or Double side weren′t significantly different(P＞0.05). Dysphagia incidence on TACI-type and brain of One-tailed were significantly different(P＜0.05).Dysphagia incidence on PACI 、LACI-type and brain of Double side were significantly different(P＜0.05). Conclusion：Dysphagia incidence on TACI 、POCI –type of OCSP classification of stroke were high. There were relevant TACI-type of OCSP classification of stroke and lesions of brain of One-tailed. There were relevant PACI、 LACI-type of OCSP classification of stroke and lesions of brain of Double side．Lesions of brain of One-tailed　or Double side can lead dysphagia of POCI-type of OCSP classification of stroke.
