The presence of thrombus is independently associated with adverse outcomes during percutaneous coronary intervention (PCI), particularly in those cases involving a large thrombus burden such as in saphenous vein grafts (SVGs) or during primary PCI. Mechanical thrombectomy devices are used to reduce the thrombus burden in such high-risk procedures to reduce the risk of distal embolization and slow flow and no-reflow. Here we describe 3 cases of successful use of a stent delivery system with a wide-bore lumen, the "five-in-six" Heartrail catheter, as a thrombectomy device in SVG lesions and primary PCI following failure of conventional simple aspiration thrombectomy catheters.
血栓的存在与经皮冠状动脉介入治疗（PCI）期间的不良结局独立相关，尤其是在那些涉及大血栓负荷的病例中，如在大隐静脉桥血管（SVG）中或在直接PCI期间。机械血栓切除术装置用于在这类高风险手术中减轻血栓负荷，以降低远端栓塞以及慢血流和无复流的风险。在此，我们描述3例成功使用具有宽内腔的支架输送系统——“六合一”Heartrail导管，作为在传统简单抽吸血栓切除术导管失败后用于SVG病变和直接PCI的血栓切除术装置的病例。
