Methods AMI patients presenting proximal coronary lesions with intracoronary thrombus were selected. We used the common coronary wire (0. 014') across the lesion after 7F guiding catheter to the ostium of coronary arteries. Aspiration catheter (Export, PercuSurge) was directly advanced over the wire to the lesion and manually aspirated the thrombus with a 20 - ml syringe at the same time. After thrombus disappeared and occluded arteries reopened, stents were directly implanted. Results 12 cases of AMI received the treatment. After aspiration, the thrombus disappeared in 8 cases, and decreased in another 4 cases. The total occluded artery was directly re- opened and the antegrade flow improved markedly after aspiration in 7 out of 8 cases. 9 patients achieved TIMI 3 flow and TMP 3 grade perfusion flow after stenting, and the other 3 cases were TMP 2. No major cardiac events took place during hospitalization. The LVEF was 64.1 ± 9. 3% before discharge. Conclusions Transcatheter aspiration of thrombus is a simple and effective method to manage the intracoronary thrombus in AMI patients.展开更多

Due to similar clinical presentations, it is very difficult to distinguish with pulmonary thromboembolism （PTE）, leading to inappropriate treatments such as anticoagulation and thrombolysis.2-5Although with improvement of imaging modalities, the diagnosis of PAIS is still based on pathological examination, and the majority of specimens are taken by surgery or autopsy.展开更多
