We conducted an up-to-date meta-analysis to assess the rate of success and complication of the TVE to conclude its efficacy and safety.

Material(s) and Method(s):

Literature was searched for relevant and potentially relevant studies from 1982 through February 2021. Studies that met our eligibility criteria and reported the main outcomes (endovascular occlusion and complication rates) were included.


Seven studies were finally selected. In total, 154 patients were reviewed with detailed BAVMs characteristics and endovascular TVE techniques. The weighted mean rate of immediate endovascular total occlusion, overall technical complication, and overall good functional outcome (mRs< 2) were 93% (95%CI=89.1-96.9%, I2=0%, P 0.487), 10.5% (95%CI=4.3-16.6%, I2=30.8%, P 0.193), and 90.9% (95%CI=85.3-96.6%, I2=26.6%, P 0.241) consecutively.


The results of TVE for BAVMs showed it is generally safe and effective in certain selected patients. However, the complementary role of TAE to TVE as a definitive endovascular treatment for BAVMs cannot be separated. More studies concerning this role need to be conducted.
