Convexity Subarachnoid Hemorrhage Soon after Starting a Direct Oral Anticoagulant in 2 Patients with Acute Infarction

Convexity subarachnoid hemorrhage (cSAH) is typically due to head trauma, but various nontraumatic causes for cSAH are known also. Nontraumatic cSAH is most commonly associated with cerebral amyloid angiopathy (CAA) in the elderly or with reversible cerebral vasoconstriction syndrome in younger subjects,1 but cSAH rarely occurs subsequent to acute ischemic stroke.2 Direct oral anticoagulants (DOACs) are used to reduce the risk of ischemic stroke and systemic embolism in patients with non-valvular atrial fibrillation and have favorable bleeding profiles as compared with warfarin,3,4 but here we describe 2 cSAH patients who experienced acute cerebral infarction shortly after starting a DOAC.
