[Bilateral hemothorax secondary to combined antiplatelet therapy with clopidogrel and acetylsalicylic acid].

Clopidogrel is a platelet aggregation inhibitor that increases the risk of bleeding complications when combined with acetylsalicylic acid. We report a rare case of a 79-year-old male treated with clopidogrel and acetylsalicylic acid after coronary angioplasty and stenting to treat unstable angina. Two months after initiation of therapy, the patient presented with symptomatic bilateral pleural effusion.
