Acute coronary dissection remains a limitation of percutaneous transluminal coronary angioplasty. For the management of acute coronary dissection, a new adjustable temporary stent catheter that can be positioned to the lesion, deployed, and retrieved at a later stage was developed. This catheter has at its distal end a spiral stent that can be reduced and expanded in a controlled fashion by external manipulations. The adjustable temporary stent catheter was applied in three clinical cases with acute coronary dissection during balloon angioplasty. In all cases, the adjustable temporary stent catheter restored blood flow when it was expanded to the lesion for 60 min and this restoration was maintained after device removal. It is envisioned that this temporary stent device may prove a useful means for the treatment of acute coronary dissection during percutaneous transluminal coronary angioplasty.
急性冠状动脉夹层仍然是经皮腔内冠状动脉成形术的一个局限性。为了处理急性冠状动脉夹层，研发了一种新型的可调节临时支架导管，该导管能够定位至病变部位，在后期进行展开及回收。此导管远端有一个螺旋支架，通过外部操作可对其进行可控的缩小和扩张。该可调节临时支架导管应用于3例球囊血管成形术期间发生急性冠状动脉夹层的临床病例。在所有病例中，当可调节临时支架导管在病变部位展开60分钟时恢复了血流，并且在移除该装置后血流得以维持。可以预想，这种临时支架装置可能会被证明是在经皮腔内冠状动脉成形术期间治疗急性冠状动脉夹层的一种有用方法。
