血管内治疗急性缺血性卒中已经成为一项标准的治疗技术。多重神经血管装置的结合使用可为技术的改良提供更多的可能性。我们描述了一种改良的取栓技术——使用远端颅内导管(distal intracranial catheter,DIC)在取栓之前半回收取栓装置。这项技术的成功运用包括回拉DIC使支架完全释放,前推DIC部分地回收支架,从而使支架在取栓之前形成锥形,更好地嵌合和固定血栓、缩短取栓行程,同时减少血管内皮损伤。该项技术可作为血栓切除术的一个良好选择,并可提高取栓效率。
Endovascular treatment of acute ischemic stroke has become a standard treatment technique. The combined use of multiple neurovascular devices may provide more possibilities for technical improvements. We describe an improved thrombectomy - using a distal intracranial catheter (DIC) to retrieve the thrombectomy device halfway before embolectomy. The successful use of this technology includes the complete release of the stent by pulling back the DIC and the partial pushing of the DIC by the forearm to form a tapered shape of the stent prior to thrombolysis to better fit and secure the thrombus to shorten the thrombectomy stroke while reducing Vascular endothelial injury. This technique is a good choice for thrombectomy and improves the efficiency of thrombectomy.
