The influence of the manual thrombus aspiration on the short term effectiveness of the percutaneous revascularization in patients with coronary artery thrombosis

Introduction: Percutaneous coronary intervention (PCI) is one of the main issues in treatment of acute coronary syndrome with ST segment elevation (STEMI). The manual thrombus aspiration was believed to improve the results of intervention especially in patients with coronary thrombosis. The aim: To explore the influence of manual thrombus aspiration on the short-termed prognosis after PCI in patients with STEMI and visible coronary thrombosis. Materials and methods: 50 patients with STEMI and visible coronary thrombosis were included for exploration. Main group (MG) consists of 25 patients to whom manual thrombus aspiration was performed and comparison group (CG) of 25 patients whom were performed just conventional PCI. Results: In the 84% patients of the MG and in 72% CG was gained ТІМІ 3 flow grade after the procedure (р=0.5). MBG 3 was reached in similar number of patients from both groups ( р=0.37). Comparison of the ejection fraction of the LV and its' wall motion score brought the same results. The trend to better indexes of glomerular filtration rate was observed in the patients of the MG (р=0.18). Need of the balloon angioplasty before stenting was the unique index improved by the manual thrombus aspiration (р=0.02). Conclisions: No significant advantages of the manual thrombus aspiration usage weren't revealed compearing to conventional PCI in our study in the patients with STEMI and visible coronary thrombosis. At the same time few insignificant trends were reveled. So the more powerful trial is needed to solve this problem.
