Aneurysms and pseudoaneurysms of coronary arteries and saphenous vein coronary artery bypass grafts: a case report and literature review.

Aneurysms or pseudoaneurysms of the native coronary arteries or bypass grafts are uncommon and represent a pathology with high morbidity and mortality. We report the diagnosis of an aneurysm of a saphenous vein coronary artery bypass graft with an atypical presentation and review incidence, modes of presentation, aetiology and proposed mechanisms of formation of this and similar entities. Complications, diagnostic clues and therapeutic options are also discussed.
