Analysis on pathogeny and clinical features of 103 young patients with cerebral infarction

Objective To analyse the causes, and clinical features of young patients with cerebral infarction. Methods Retrospective study of chnieal data of 103 youth patients with cerebral infarction was carried out. Results Ninety-four patients had definite pathogeny （ 91.26% ）, Nine patients had unclear pathogeny （ 8. 74% ）.
