Endovascular embolization in treatment of brain arteriovenous malformation combined with aneurysms / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the value of endovascular embolization in treatment of brain arteriovenous malformation (BAVM) combined with aneurysms. Methods Totally 46 patients with brain arteriovenous malformation combined with aneurysm were enrolled. Patients with Redekop type Ⅱa and III BAVM were embolized with Onyx combined with coils (group A), while with Redekop type and Ⅱb BAVM were embolized with Onyx combined with coil or only Onyx (group B). Then the effect of embolization was evaluated using Glasgow outcome scale (GOS) score. Cerebral angiography was reviewed 3 months after treatment to observe whether the lesions recurred or not. Results: The postoperative GOS of group A was 4.70±0.47. In group B, GOS of patients embolized with Onyx combined with coil (4.75±0.45) was significantly higher than those with only Onyx (4.33±0.49; t=2.159, P=0.042). One patient died, 45 patients underwent cerebral angiography after 3 months, and no recurrence was found. Conclusion:Endovascular embolization is effective for brain arteriovenous malformation with aneurysms, and embolization using Onyx combined with coil is better than only Onyx embolization.
