Thrombin injection successfully thrombosed all pseudoaneurysms without complication apart from patient 12* in whom arterial thrombus developed immediately after the injection. The thrombus dissolved spontaneously without any vascular intervention.
PTCA, percutaneous transluminal coronary angioplasty; IABP, intra-aortic balloon pump; A, aspirin; C, clopidogrel; H, heparin.
