急性心肌梗死是临床常见的危急重症,及时并完全开通梗死血管是挽救濒死心肌的关键。经皮冠状动脉介入术(percutaneous coronary intervention,PCI)是开通闭塞血管的最佳方法,然而部分患者PCI术后心肌灌注不理想,可能与梗死血管远端血栓负荷高导致微循环栓塞发生有关。血栓抽吸在祛除栓塞物质后理论上可改善心肌灌注,但多项临床试验显示血栓抽吸后患者能否获益尚存争议,本文就近年来关于血栓抽吸导管治疗急性心肌梗死效果的研究进展予以综述。
Acute myocardial infarction is a common clinical critically ill, timely and fully open the infarct blood vessels is the key to saving the dying myocardium. Percutaneous coronary intervention (PCI) is the best way to open the occluded blood vessels. However, some patients with perioperative myocardial perfusion is not ideal, which may be related to the occurrence of microcirculation embolism caused by the high load of distal thrombosis. Thrombus aspiration can theoretically improve myocardial perfusion after removing the embolic material. However, many clinical trials have shown that it is still controversial whether patients can benefit from thrombus aspiration. In this paper, recent advances in the study of thrombus aspiration catheters in the treatment of acute myocardial infarction To be reviewed.
