In brain haemorrhage due to conditions like Aneurysm and Arterio-Venous Malformation (AVM), the main effort is towards sealing the leakage of blood. In a good number of cases, this can be achieved by a modality called ENDOVASCULAR TREATMENT which is done by a specialist doctor called NEURO-INTERVENTIONIST. The basic principle is to reach the sight of leakage with the help of DSA and put either a special kind of glue or special coils. If the sight of leakage cannot be reached by DSA, then it is done by surgery. Here, the specialised NEURO-VASCULAR SURGEONS come to the rescue.
