*6.3.5 Palliative embolization*

Infrequently, cAVMs may cause focal neurological deficits as a result of vascular steal or local venous hypertension. In these situations, decreased venous hypertension and steal by embolisation of select, high-flow feeders may improve focal neurological deficit and quality of life. However, there is no substantial evidence to support this approach and further studies are needed [23, 34, 35].
