Coronary artery dissection is a well-known complication of percutaneous coronary interventions. In this setting, coronary artery dissection is caused by mechanical injury of the arterial wall. However, dissection may also occur spontaneously. In both situations, an intimal tear or dissection allows blood entering and separating the layers of the coronary arterial wall. Despite percutaneous approach is still the preferred and the quickest way to restore coronary flow, it remains challenging. One of the main reasons for procedural failure is due to the difficult advancement of a guidewire into the true lumen. In such situation, the ideal wire should have a soft tip, high torque control, and excellent flexibility. Assuming that, the "new rope coil" composite core Suoh 0.3 guidewire, with its unique combination of characteristics, could allow better orientation insight into a dissected coronary artery increasing the chance of procedural success. We collected a case series of nine consecutive patients in which the Suoh 0.3 guidewire was able to gain the true lumen distally to a dissected segment.
冠状动脉夹层是经皮冠状动脉介入治疗的一种已知并发症。在这种情况下，冠状动脉夹层是由于动脉壁的机械损伤引起的。然而，夹层也可能自发发生。在这两种情况下，内膜撕裂或夹层都会导致血液进入并分离冠状动脉壁的各层。尽管经皮方法仍然是恢复冠状动脉血流的首选和最快方法，但仍然具有挑战性。手术失败的主要原因之一是导丝难以进入真腔。在这种情况下，理想的导丝应该具有柔软的尖端、高扭矩控制和出色的柔韧性。假设“新型绳索线圈”复合芯 Suoh 0.3 导丝具有独特的特性组合，可使导丝更好地进入夹层冠状动脉，增加手术成功的机会。我们收集了连续 9 例患者的病例系列，其中 Suoh 0.3 导丝能够在夹层段的远端获得真腔。
