Carotid Artery Dissection with Low Bleeding Risk and High-Risk Radiological Features
Clinical Scenario
This protocol addresses cervical artery dissection in patients who have a low risk of bleeding but present with high-risk radiological features — findings recognised as significant predictors of ischemic stroke following dissection.
High-Risk Radiological Features
The following imaging findings define the high-risk radiological profile in this setting:
- Intraluminal thrombus
- Severe stenosis
- Occlusive dissection
These radiographic findings are known predictors of ischemic stroke after dissection. In the context of low bleeding risk, their presence directly informs the management strategy.
Management Approach
Anticoagulant therapy is the cornerstone of the approach for this scenario. The full regimen — including the specific agents, sequence, and duration — is available in the complete protocol.

- The presence of radiographic high-risk features that are known predictors of ischemic stroke after dissection (such as severe stenosis or occlusion, intraluminal thrombus) in patients with low risk of bleeding may warrant anticoagulation therapy.
- Parenteral followed by oral anticoagulation may be considered in particular in patients at low risk of intracranial hemorrhage (small infarct size, no intradural extension, and no intracranial hemorrhage) but at high risk for ischemic stroke (eg, intraluminal thrombus, occlusive dissection).
