Recently, tenecteplase (TNK) has been used for intravenous thrombolysis in acute ischemic stroke (AIS). Although spontaneous subarachnoid hemorrhage (SAH) following thrombolysis with tissue plasminogen activator has been reported, there is a lack of literature regarding TNK-induced nonaneurysmal spontaneous SAH. Our index case received intravenous TNK within an hour of symptom onset of AIS. Following deterioration of sensorium, repeat noncontrast computed tomography was performed, which showed diffuse SAH. Cerebral angiography did not reveal any aneurysm. Nonaneurysmal SAH can be a complication of TNK thrombolysis, which is not reported in literature. Knowledge of this possible adverse reaction is critical for appropriate counseling and management.
Key-words:
Stroke - subarachnoid hemorrhage - tenecteplase - thrombolysis
