RESUMO
Hemoptysis in childhood is a common clinical manifestation whose severity depends on the rate at which hemoptysis occurs and the degree of bleeding.Hemoptysis occurs for a variety of reasons,among which hemopty-sis correlated with vessels is one of the factors.Although the incidence rate is not common,it is mostly the first cause of hemoptysis.Hemoptysis correlated with vessels exit a relatively backward diagnosis in clinical which due to the gradual process of the diagnosis,and its treatment and prognosis of the disease depends on the type,number,morphology of ab-normal vessels and degree of bleeding.It is important to earlier recognize hemoptysis correlated with vessels,develop a standardized diagnostic procedure,setup appropriate treatment plans and timing for medical staff so as to improve the diagnosis and treatment of the disease and reduce the incidence of complications and hemoptysis recurrence rate.
