Catalunya General University Hospital offers dedicated Endovascular surgery for AVM supported by experienced neurointerventional specialists, advanced angiography systems, and modern catheterization facilities. Established in 1984, the ISO accredited hospital is situated in Barcelona, Spain and has 300 beds supporting specialized cerebrovascular treatment.

Endovascular Surgery for AVM involves accessing the abnormal vascular network from within the blood vessels rather than through an open brain operation. Under real-time imaging guidance, the specialist advances a microcatheter toward selected feeding arteries and introduces an embolic agent to reduce or eliminate blood flow through the AVM. The goal may be to reduce the size or vascularity of the malformation and make subsequent treatment safer or more effective. Detailed angiographic assessment is essential for treatment planning.
