Long-term antiplatelet treatment for innominate vein aneurysm.

Aneurysms of thoracic veins are rare lesions and their therapeutic management is not clearly determined. We present a 60-year old man with an asymptomatic right innominate vein aneurysm. The patient had been operated on 10 years ago for coronary artery bypass and was under antiplatelet treatment. In a retrospective inspection of his chest X-rays, we found that the aneurysm had been existent for at least 10 years. We suggested conservative treatment and over a 5-year follow-up, the patient has remained asymptomatic. Our patient is alive 15 years with thoracic vein aneurysm and antiplatelet treatment.
