Despite advancements in mechanical thrombectomy (MT) in the treatment of large vessel occlusions, failure to achieve recanalization remains a challenge in 10 – 30% of patients. Several underlying pathologies have been postulated in refractory MT, including intracranial atherosclerotic stenosis, intracranial dissection, and recalcitrant emboli. Rescue strategies to maximize recanalization rates, such as alternative access routes, local thrombolysis, stent-assisted angioplasty, and acute “rescue” stenting, have been proposed. Considered an emerging treatment strategy for refractory MT, rescue stenting (RS) has been shown in non-randomized observational studies as a safe and effective strategy for increasing reperfusion rates and consequently improving clinical outcomes. The effective use of RS approach requires consideration of patient-specific characteristics, clot characteristics, and lesion anatomy. This review provides an overview of the understanding of refractory MT, epidemiology, pathophysiology, current evidence supporting RS in the anterior and posterior circulation, stents used, endovascular techniques, patient selection criteria, antithrombotic use, risks, and complications.
