Abstract  Objective：To explore risk factors of occurrence of pulmonary embolism in patients with intracerebral hemorrhage，and establish risk prediction model.Methods：213 patients with intracerebral hemorrhage accepted by our hospital from July 2017 to October 2019 were selected as modeling group，and 82 patients with intracerebral hemorrhage accepted by our hospital from November 2019 to November 2020 were selected as verification group.Clinical data of the patients were collected.Risk factors of occurrence of pulmonary embolism in patients with intracerebral hemorrhage were screened by univariate analysis and multi-factors analysis.And risk prediction model was established.Results：71 of the 295 patients with intracerebral hemorrhage occurred pulmonary embolism，the rate was 24.07%.Age≥65 years old，diabetes，bed time≥7 d，deep venous thrombosis，chronic lung disease，history of surgical surgery were independent risk factors of occurrence of pulmonary embolism in patients with intracerebral hemorrhage（P<0.05）.Based on above risk factors，risk prediction model of occurrence of pulmonary embolism in patients with intracerebral hemorrhage was built.Correct curve in modeling group and verification group were closer to the ideal curve.C-index of modeling group and verification group were 0.881［95%CI（0.858，0.904）］ and 0.843 ［95%CI（0.805，0.881）］，respectively.Conclusions：The incidence of pulmonary embolism in patients with intracerebral hemorrhage is higher.Age≥65 years old，diabetes，bed time≥7 d，deep venous thrombosis，chronic pulmonary disease，history of surgical surgery were independent risk factors of occurrence of pulmonary embolism in patients with intracerebral hemorrhage，with higher accuracy.
