〔Abstract〕 Objective To investigate the effect of intravascular interventional embolization on hemorrhage of Occult Cerebrovascular Malformation (OVMS). Methods 72 patients with ovms bleeding treated in Maoming people's Hospital from June 2019 to June 2021 were randomly divided into control group and observation group, with 36 cases in each group. The control group was treated with excision of abnormal blood vessels, and the observation group was treated with intravascular interventional embolization; The clinical effect, operation time, intraoperative bleeding and complications were observed. Results The total effective rate in the observation group was 97.22%, significantly higher than 80.56% in the control group (P < 0.05); The amount of intraoperative bleeding in the observation group was less than that in the control group, and the operation time was shorter than that in the control group (P < 0.05); After 3 months of follow-up, the incidence of complications was 5.56% in the observation group and 30.56% in the control group (P < 0.05). Conclusion Intravascular interventional embolization is effective in the treatment of ovms bleeding, which can effectively shorten the operation time, reduce the amount of intraoperative bleeding and reduce the incidence of complications.
