Neurointerventional tools and techniques for coronary thrombus removal. A case-based review

Published:September 09, 2022DOI:


      Due to the negative results of randomized aspiration thrombectomy studies, its role in myocardial infarction has been limited to high thrombus burden and/or failed vessel recanalization, with little technological advancement over the last years. In contrast, there has been rapid progress in mechanical thrombectomy in stroke, which is understandable as most ischemic cerebrovascular accidents have an embolic etiology.
      We present three transradial procedures wherein neurointerventional catheters were used as a first-line device for en bloc removal of large clots lodged distally in tortuous coronary anatomy. First-pass reperfusion was achieved in all the cases, without dissection, distal embolization, or the no reflow phenomenon.

      Learning objective

      In the case of large clots, where coronary aspiration devices fail, neurointerventional catheters may be considered as a rescue strategy. They provide large aspiration lumen and excellent trackability with atraumatic design. Many other neurointerventional techniques can be easily adopted into the coronary armamentarium, possibly increasing the safety and efficacy of thrombus aspiration.
