A new catheter was used in an attempt to re-establish coronary flow in six patients with acute occlusion after angioplasty and prior to emergency coronary artery bypass surgery. All patients suffered from severe chest pain, and the electrocardiogram showed signs of acute transmural ischemia. A reperfusion catheter manufactured by Advanced Cardiovascular Systems (ACS) has 36 side holes spirally arranged along the distal 10 cm. It is introduced over an exchange wire. After the catheter was positioned across the occlusion, five patients had complete relief of chest pain, and another patient had partial relief. The electrocardiogram normalized in all six patients (in one only initially). Two patients developed a limited myocardial infarction, but four did not. The time between introduction of the reperfusion catheter and aorta cross clamping varied between 1.5 and 6.5 hours, and there were no complications related to its use. We conclude that the ACS reperfusion catheter is useful in re-establishing coronary blood flow after failed angioplasty and prior to emergency coronary artery bypass surgery.
一种新型导管被用于尝试在6例血管成形术后急性闭塞且在紧急冠状动脉搭桥手术前的患者中重建冠状动脉血流。所有患者均患有严重胸痛，且心电图显示急性透壁性缺血迹象。由先进心血管系统公司（ACS）制造的再灌注导管在其远端10厘米处有36个螺旋排列的侧孔。它通过交换导丝引入。在导管跨过闭塞部位定位后，5例患者胸痛完全缓解，另1例患者部分缓解。所有6例患者的心电图均恢复正常（仅1例最初即恢复正常）。2例患者发生局限性心肌梗死，但4例未发生。再灌注导管引入至主动脉交叉钳夹之间的时间在1.5至6.5小时之间，且未出现与使用该导管相关的并发症。我们得出结论，ACS再灌注导管在血管成形术失败后及紧急冠状动脉搭桥手术前重建冠状动脉血流方面是有用的。
