From the Guidelines
Management of a patient with a cerebral vascular accident (CVA) that has undergone hemorrhagic conversion requires immediate discontinuation of all anticoagulant and antiplatelet medications and careful control of blood pressure, typically maintaining systolic pressure below 140-160 mmHg. The management approach should prioritize preventing further bleeding and reducing intracranial pressure, with considerations for intracranial pressure monitoring and interventions such as head elevation, mild hyperventilation, osmotic therapy, and in severe cases, surgical decompression 1. Key aspects of care include:
- Discontinuing anticoagulant and antiplatelet medications
- Controlling blood pressure with IV medications like labetalol, nicardipine, or clevidipine
- Considering intracranial pressure monitoring and interventions
- Initiating seizure prophylaxis with levetiracetam
- Managing temperature and glucose levels
- Early neurosurgical consultation for potential hematoma evacuation
- Initiating rehabilitation with physical, occupational, and speech therapy. Intracranial pressure monitoring may be necessary, with the decision to use a ventricular catheter or a parenchymal catheter device based on whether there is a need to drain cerebrospinal fluid to treat hydrocephalus or elevated ICP, as evidenced by the guidelines for the management of spontaneous intracerebral hemorrhage 1.
From the Research
Management Approach for CVA with Hemorrhagic Conversion
The management of a patient with a cerebral vascular accident (CVA) that has undergone hemorrhagic conversion is complex and requires a multidisciplinary approach.
- The treatment of hemorrhagic conversion includes blood pressure management, reversing coagulopathy, and managing its complications including increased intracranial pressure 2.
- Reversing coagulopathy is crucial in limiting hematoma expansion and improving outcomes in patients with antithrombotic-associated intracranial hemorrhage 3.
- The use of vitamin K, fresh frozen plasma, and platelet transfusion has been shown to be effective in arresting the progression of intracranial hemorrhage in patients taking anticoagulant and antiplatelet agents 4.
- Temporary interruption of anticoagulation therapy may be safe for patients with intracranial hemorrhage and mechanical heart valves, but without previous evidence of systemic embolization 5.
- The risk of embolization may be greater for patients with atrial fibrillation, cage-ball valves in the mitral position, and reduced ventricular function 5.
- The management of anticoagulant-related hemorrhage requires a careful balance between the risk of thromboembolism and the risk of hemorrhage, and the use of antagonists such as protamine sulfate, vitamin K1, and antifibrinolytic drugs may be necessary in treating hemorrhagic events 6.
Reversal of Antithrombotics
- The Neurocritical Care Society and Society of Critical Care Medicine have developed an evidence-based practice guideline for the reversal of antithrombotics in intracranial hemorrhage 3.
- The guideline provides recommendations for reversal of vitamin K antagonists, direct factor Xa antagonists, direct thrombin inhibitors, unfractionated heparin, low-molecular weight heparin, heparinoids, pentasaccharides, thrombolytics, and antiplatelet agents in the setting of intracranial hemorrhage 3.
- The use of specific reversal strategies, such as vitamin K and fresh frozen plasma, may be effective in reversing coagulopathy and limiting hematoma expansion 4, 3.
