Management of Post-IVT Brain Hemorrhage
Immediately stop the alteplase infusion, obtain emergent non-contrast head CT, send coagulation labs (CBC, PT/INR, aPTT, fibrinogen, type and cross-match), and administer cryoprecipitate 10 units plus tranexamic acid 1000 mg IV or aminocaproic acid 4-5 g IV to reverse the coagulopathy. 1
Immediate Actions
Stop the infusion immediately if the patient develops severe headache, acute hypertension, nausea, vomiting, or neurological worsening during or after alteplase administration. 1
Laboratory Evaluation
- Send stat labs: Complete blood count, PT (INR), aPTT, fibrinogen level, and type and cross-match 1
- Obtain emergent non-contrast head CT to confirm and characterize the hemorrhage 1
Pharmacologic Reversal (Class IIb, LOE C-EO)
First-Line Hemostatic Agents
Cryoprecipitate (contains factor VIII): Administer 10 units infused over 10-30 minutes; onset occurs in 1 hour and peaks at 12 hours. Give additional doses if fibrinogen level remains <200 mg/dL. 1
Antifibrinolytic therapy (choose one):
- Tranexamic acid: 1000 mg IV infused over 10 minutes (peak onset in 3 hours) 1
- OR ε-aminocaproic acid: 4-5 g IV over 1 hour, followed by 1 g IV infusion until bleeding is controlled (peak onset in 3 hours) 1
Supportive Management
Blood Pressure Control
- Maintain strict BP control: Target systolic BP ≤180 mm Hg and diastolic BP ≤105 mm Hg 1
- Increase monitoring frequency if BP exceeds these thresholds 1
Additional Supportive Measures
- Manage intracranial pressure (ICP) and maintain adequate cerebral perfusion pressure (CPP) and mean arterial pressure (MAP) 1
- Control temperature and glucose levels 1
- Avoid placing nasogastric tubes, indwelling bladder catheters, or intra-arterial pressure catheters unless absolutely necessary 1
Specialist Consultation
Obtain immediate consultations:
Critical Monitoring
Neurological assessments:
- Every 15 minutes during the first 2 hours after hemorrhage detection 1
- Every 30 minutes for the next 6 hours 1
- Hourly until 24 hours post-event 1
Important Caveats
The evidence for reversal strategies is limited (Class IIb, LOE C-EO), meaning these recommendations are based on expert opinion and observational data rather than randomized trials. 1 However, the high mortality rate (75% in-hospital mortality for symptomatic ICH after thrombolysis) 2 justifies aggressive intervention despite limited evidence.
Continued bleeding occurs in approximately 40% of patients with symptomatic ICH after thrombolysis who have follow-up imaging, suggesting a critical window for intervention. 2 This underscores the importance of rapid reversal of coagulopathy.
Do not delay treatment to obtain all laboratory results if clinical suspicion is high—initiate reversal measures while awaiting confirmation. 1
Avoid antiplatelet and anticoagulant therapy for at least 24 hours after the hemorrhage, and only restart after repeat imaging confirms stability and clinical improvement. 1
