About Treatment ProceduresIt is the youngest off shoot of Neurosciences and can also be called a Neurosciences sub-specialty of the 21st century.
It is a form of neurological surgery in which various forms of strokes (hemorrhagic or ischemic) or other forms of vascular disease in the brain are approached from within the lumen of the vessel (usually an artery but can be a vein) by a needle puncture in the groin rather than craniotomy (an operation where skull bone is cut open) and brain disease is treated from outside. It involves the use of miniature catheters (called microcatheters) and wires for the treatment of various complex neurovascular diseases. In fact the treatment of stroke has seen a paradigm shift with the evolution of this modality.
It is one of the complex and intricate types of neurological surgery where in a surgeon manipulates his instruments (in this case miniature wires, catheters and balloons) from a distance under the image guidance. These small devices are used in the brain arteries to either stop blood flow to an abnormal structure (aneurysm / AVM / tumor), establish flow in a blocked vessel (stroke).
Neuro-intervention is not exactly a new therapy; it has evolved itself from cerebral angiography which was first done in 1926 for diagnosis of brain disorders. This particular treatment option got a major boost in 2002 after publication of major trial called ISAT trial which established safety of this form treatment over open surgery. Since then it often represents a viable alternative to surgery”
