Would you use sumatriptan in a patient with a history of cerebral aneurysm rupture?  

Yes. There is no evidence that the use of triptan in patients with an unruptured cerebral aneurysm, or in those who have a history of ruptured aneurysm that have been coiled or clipped, increases the risk of serious adverse events. I would not use them in the setting of acute subarachnoid hemorrhage...
