Progression of bilateral internal carotid artery dissection during antiplatelet therapy

Area of Science:

• Neurology
• Vascular Medicine
• Stroke Research

Background:

• Bilateral internal carotid artery dissection (ICAD) is an uncommon yet significant cause of stroke, particularly in younger populations.
• Current treatment guidelines for ICAD often recommend anticoagulation or antiplatelet therapy for stroke prevention, but evidence supporting these interventions is limited and controversial.
• The comparative efficacy of anticoagulation versus antiplatelet therapy in managing ICAD remains inadequately defined.

Observation:

• A 30-year-old male patient presented with progressive bilateral ICAD.
• The patient was undergoing treatment with antiplatelet agents at the time of presentation.
• Despite antiplatelet therapy, the dissection showed signs of progression.

Findings:

• The case highlights a potential adverse effect of antiplatelet therapy in the context of ICAD.
• It raises the possibility that both antiplatelet and anticoagulant medications could contribute to the enlargement of intramural hematomas in ICAD.
• This observation challenges the established treatment paradigms for ICAD.

Implications:

• Further research is warranted to investigate the role and safety of antiplatelet and anticoagulant agents in managing ICAD.
• Clinical practice guidelines for ICAD may need re-evaluation based on emerging evidence regarding medication risks.
• This case underscores the importance of considering medication effects on dissection progression and patient outcomes.
