Cerebral Revascularization is a highly specialized technique used for the treatment of complex brain aneurysms, cranial base tumors and cerebrovascular occlusive diseases.
It is the most modern and important surgical option for prevention of the cerebral ischemia.
The main goal of cerebral revascularization surgery is to make possible the more blood flow to areas of brain ischemia. It thereby improves inter cranial circulation. Brain ischemia or cerebral ischemia is a condition of insufficiency of blood flow to the brain. Adequate availability of oxygen will become difficult.
- Poor cerebral blood flow
- Moyamoya disease- It is an occlusive disease of brain in which certain arteries are getting constricted and consequently blocking smooth flow of blood. Revascularization surgery needs to be performed here to treat this. But sometimes, indirect vasculrization is much enough in case of adult patients as it considers cerebral blood flow measurement.
- Skull base tumors
- Cerebral ischemic attack
- Occluded common carotid artery- It is treated by subclavian to external carotid artery bypass followed by Superficial temporal Artery middle cerebral artery (STA-MCA) Bypass.
- Giant anterior circulation aneurysms- Treatment by definitive exclusion from the circulation by reconstructing and preserving all afferent and efferent branches of arteries in the cerebral aneurysm using clips. It is slightly a difficult task as it involves both parent artery and affected branches.
- A patient with Collateral circulation is marginal.
- Unclipable brain aneurysms- Use of radial artery grafts in treatment procedure. It needs to connect extra cranial vessel to intracranial vessel.
These procedures seem to be highly effective in relieving symptoms and they minimize the risks of cerebral and upper extremity revascularization.
