[A case of spontaneous closure of left main coronary artery false aneurysm and stent thrombosis 11 years after coronary artery stenting].

This is the presentation of a case of formation of traumatic iatrogenic false aneurysm of left main coronary artery and its spontaneous closure combined with acute thrombosis of the stented segment of anterior interventricular artery (AIA) 11 years after initial procedure. False aneurysm was a consequence of dissection of arterial wall due to mechanical trauma by relatively stiff tip of guide wire and arterial wall hematoma extending to adventitia. Hematoma formation could be facilitated by thrombolytic therapy with streptokinase urgently carried out for acute AIA thrombosis after balloon angioplasty. Despite completion of processes of arterial wall repair at the implantation site confirmed by angiography 3.5 years after initial stenting development of novel atherosclerotic lesions and thromboses can occur in very remote period (after 11 years).
