Etiology dependent: This depends on the cause of your first subarachnoid hemorrhage. If it was aneurysmal, and the aneurysm was clipped or coiled and there are no others--then unlikely. This assumes you manage your blood pressure and there are no genetic risk factors.If it was traumatic and you suffer no further trauma-- unlikely. There are occasional subarachnoid hemorrhages where no cause is found.

Provided original answer
It would be very unlikely that you would suffer a second event given there are no residual aneurysms and you have no genetic pre-disposition for aneurysm formation.

In literature, benign paroxysmal idopathic subarachnoid hemorrhage means we have no answer and can find no bleeding vessel. These comprise about 10-15% of all subarachnoid hemorrhages. Best of luck to you.

Clipped or coiled: Referring to aneurysmal subarachnoid hemorrhage, these are treated either surgically with a clip or endovascularly with coils. The size of the mouth of the aneurysm dictates the type of procedure. Very wide mouthed aneurysms are typically approached surgically, narrow mouth aneurysms, endovascularly. Traumatic sah is treated medically, there may be surgical intervention for other brain injury.
