Objective:
We sought to report transarterial Onyx embolization of residual brain arteriovenous malformation (AVM) after surgical resection.
Methods:
From January 2017 to January 2019, 7 patients with residual AVM after surgery were treated by transarterial Onyx embolization. Demographics, angioarchitectural characteristics, complications, and results were retrospectively reviewed.
Results:
All patients presented initially with a ruptured AVM. Residual AVM was found on control angiograms within 1 month after surgery. All residual AVMs were cured by transarterial Onyx embolization. One patients experienced feeding artery perforation without adding new neurologic deficits.
Conclusions:
Complete obliteration of residual AVMs can be obtained by salvage transarterial Onyx embolization.

If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
