Two weeks: Traditionally if an angiogram wasn't done at the time of the event, we usually waited about 14 days for the vasospasm to cease. Of course it was always at the discretion of the neurosurgeon and neurologists involved. Not all cerebral aneurysms will be at the circle of Willis . Close discussions with the treating doctors is really need. Best wishes
