Thrombus Aspiration Complicated by Systemic Embolization in Patients With Acute Myocardial Infarction

Percutaneous coronary intervention (PCI) is the preferred treatment modality for patients with acute coronary syndrome, but the "no-reflow" phenomenon, primarily caused by distal embolism, has hampered the effectiveness of PCI as regards reperfusion of the myocardium. Thrombus aspiration is sometimes used to reduce the incidence of distal embolism, but potentially the procedure may be complicated by upstream thrombus migration and systemic embolism. Two cases of systemic embolism during thrombus aspiration are presented. One patient had embolism of the cerebral artery and the other embolism of the left radial artery. It is suggested that a large-lumen guiding catheter with a deep-seated position and gentle injection of contrast medium should be used for thrombus aspiration. (Circ J 2009; 73: 1356-1358)
