Gastrointestinal bleed with clopidogrel and aspirin

Area of Science:

• Cardiovascular Medicine
• Pharmacology

Background:

• Anti-platelet drugs are crucial for preventing thrombosis in systemic-to-pulmonary artery shunts.
• Aspirin is the traditional anti-platelet agent, with clopidogrel emerging as a potential alternative or adjunct therapy.

Purpose of the Study:

• To report a case of severe gastrointestinal bleeding in a patient with a shunt on dual anti-platelet therapy.
• To highlight the potential risks associated with combining aspirin and clopidogrel in this patient population.

Main Methods:

• Case report detailing a near-fatal gastrointestinal bleed.
• Review of existing literature on anti-platelet drug combinations for shunt management.

Main Results:

• A patient on combined aspirin and clopidogrel therapy for shunt thrombosis prophylaxis experienced a life-threatening gastrointestinal hemorrhage.
• The combination of aspirin and clopidogrel is associated with an increased risk of significant bleeding events.

Conclusions:

• Caution is strongly recommended when prescribing combined aspirin and clopidogrel for patients with systemic-to-pulmonary artery shunts.
• Further prospective studies are needed to thoroughly evaluate the safety and efficacy of dual anti-platelet therapy in this context.
