From the Guidelines
For a patient with basilar artery near total occlusion and atrial fibrillation, a Direct Oral Anticoagulant (DOAC) is generally recommended over warfarin for long-term management, as stated in the 2024 ESC guidelines for the management of atrial fibrillation 1. Among DOACs, the choice of specific medication should be based on patient-specific factors, including renal function, medication adherence capability, cost considerations, and drug interactions. The 2024 ESC guidelines recommend DOACs (apixaban, dabigatran, edoxaban, and rivaroxaban) over VKAs (warfarin and others), except in patients with mechanical heart valves and mitral stenosis 1. Key considerations include:
- Renal function: Regular monitoring is essential, particularly with dabigatran.
- Medication adherence: Patient capability to adhere to the prescribed regimen.
- Cost considerations: The cost of the medication and any associated monitoring.
- Drug interactions: Potential interactions with other medications the patient is taking. The recommendation for anticoagulation in this scenario stems from the high risk of recurrent cardioembolic stroke in patients with atrial fibrillation, particularly with existing cerebrovascular disease as evidenced by the basilar artery occlusion, as supported by the 2024 ESC guidelines 1. It is crucial to individualize anticoagulant therapy based on the risk of thromboembolism and bleeding, as well as the patient’s values and preferences, in line with the recommendations from the 2020 ACC expert consensus decision pathway for anticoagulant and antiplatelet therapy in patients with atrial fibrillation or venous thromboembolism undergoing percutaneous coronary intervention or with atherosclerotic cardiovascular disease 1.

Long-term Management Options
In a patient with basilar artery near total occlusion and a history of Atrial Fibrillation (AFib), the choice between a Direct Oral Anticoagulant (DOAC) and Dabigatran (Pradaxa) for long-term management depends on various factors.
- Efficacy and Safety: Studies have shown that DOACs, including apixaban, rivaroxaban, and dabigatran, are effective in preventing stroke and systemic embolism in patients with AFib 2, 3.
- Comparison of DOACs: A study found that dabigatran was more effective than warfarin in ischemic stroke prevention, especially in patients with a history of stroke or TIA 4.
- Valvular Heart Disease: Another study suggested that dabigatran, rivaroxaban, and apixaban may be safely used in AF patients with certain types of valvular heart disease, such as aortic stenosis, aortic regurgitation, and mitral regurgitation 5.
- Advantages of DOACs: DOACs have simplified long-term anticoagulant therapy and improved its safety, with the potential to reduce the global burden of thrombosis 6.
Considerations for Basilar Artery Near Total Occlusion
- Increased Risk of Ischemic Events: Patients with basilar artery near total occlusion are at increased risk of ischemic events, and the choice of anticoagulant should take this into account.
- Bleeding Risk: The bleeding risk associated with each anticoagulant should also be considered, as patients with a history of AFib are already at increased risk of bleeding.
