"Dr. Roth recommends getting a CT and CT angiogram in patients with new onset of thunderclap headaches. Even when subarachnoid hemorrhage has been ruled out with a lumbar puncture, the angiogram may reveal RVCS."This may be the case for post party and pregnant patients. There is a section bias to this recommendation from the perspective of someone who only sees this population. This cannot be generalized to all comers in ER.
Further do you not think that for the CTA to show the pathology in discussion that it needs to be done during the symptoms? Are you going to see vasospasm when the pt is asymptomatic?
What you do matters.
