Abstract:
Objective To explore the value of interventional therapy in unruptured intracranial aneurysms combined with brain arteriovenous malformations (BAVM).Methods Data of 23 patients with unruptured aneurysms combined with BAVM were retrospectively analyzed.All patients were treated with interventional embolization,and the embolization methods were choosen according to the Redekop classification.The proximal or distal hemodynamic aneurysms were embolized with coils,and the intranidal aneurysms were embolized with Onyx.The outcome was assessed by the Glasgow outcome score (GOS) one week after treatment.DSA scan was used to observe whether there was recurrence during 3-6 months after embolization.Results Totally there were 36 aneurysms in 23 patients,including 8 intranidal aneurysms,16 proximal flow-related aneurysms,11 distal flow-related aneurysms and 1 unrelated aneurysm.Embolizations of 16 proximal hemodynamic aneurysms and l0 distal hemodynamic aneurysms were done with coils.And embolization of 8 intranidal aneurysms were done with Onyx.One distal hemodynamic aneurysm was not embolized due to the difficulty of embolization and the regular shap of aneurysm;and the patient died of cerebral hernia caused by intracranial hemorrhage on the sixth day after embolization.Because it was more suitable for surgical clipping,1 unrelated hemodynamic aneurysm was not embolized.In 23 cases,BAVM were completely embolized in 7 cases and incompletely embolized in 16 cases.A week after operation,the GOS score were 5 in 19 cases and 4 in 3 cases.The GOS score was not evaluated in the dead case.Except for 1 cases of death,the other 22 cases were followed up after embolization.No recurrence and intracranial hemorrhage occurred.Conclusion Interventional treatment of unruptured intracranial aneurysms combined with BAVM is safe and effective.Making treatment plan according to the hemodynamic characteristics of lesions and completely embolizing all lesions to prevent postoperative bleeding is helpful to improve the prognosis of patients.
