Background:
The objective of this study was to assess the rate of symptomatic intracerebral hemorrhage (SICH) in patients given thrombolytic therapy for acute ischemic stroke (AIS) after recent transient ischemic attack (TIA).
Methods:
This was a multicenter study of patients with confirmed TIA within 7 days before an AIS that was treated with intravenous (IV), intra-arterial (IA), or mechanical thrombolysis. A total of 23 cases were identified.
Results:
The median time interval between index TIA and AIS was 9 hours. The median National Institutes of Health Stroke Scale score at the time of AIS was 12. The median time interval between stroke onset and thrombolytic treatment was 90 minutes. Thrombolytic therapies included IV thrombolysis (70%), IA thrombolysis (17%), IA and mechanical thrombolysis (9%), and IV followed by IA and mechanical thrombolysis (4%). The rate of postthrombolysis SICH in this group was 8.6% (2/23).
Conclusions:
The rate of SICH in our cohort appears similar to overall postthrombolysis hemorrhage rates.
