Endovascular Thrombectomy

Non-vitamin K antagonist oral anticoagulants have provided an optimization of management of patients in the prevention of stroke in nonvalvular atrial fibrillation. The lack of an effective reversal agent has remained a challenge to these agents’ widespread utilization. Idarucizumab, a specific reversal agent for dabigatran, is approved in many countries including India. However, there is limited data for its use for Indian patients. We are reporting one of the cases of its use in India where it successfully reversed dabigatran prior to mechanical thrombectomy in acute ischemic stroke.

The most commonly used therapeutic option for the prevention of ischemic stroke in patients with atrial fibrillation is new- or old-generation oral anticoagulants. New oral anticoagulants are at least as effective as old-generation oral anticoagulants in the prevention of ischemic stroke, with a reduced risk of life-threatening hemorrhage. Moreover, the constant monitoring of these drugs in the patient’s blood is not required during routine use. However, ischemic stroke can still occur in these patients. Therefore, the aim of this study was to investigate the pattern of risk factors for ischemic stroke in patients with atrial fibrillation treated with new oral anticoagulants. Our multicenter retrospective study involved 2032 patients with acute ischemic stroke. The experimental group consisted of 256 patients with acute ischemic stroke and nonvalvular atrial fibrillation, who were treated with new oral anticoagulants. The control group consisted of 1776 ischemic stroke patients without coexisting atrial fibrillation. The results of our study show that patients with atrial fibrillation treated with new oral anticoagulants are more likely to display thrombotic, proatherogenic, and proinflammatory factors in addition to the embolic factors associated with atrial fibrillation. Therefore, solely taking new oral anticoagulants is insufficient in protecting this group of patients from ischemic stroke.

Abstract Background The optimal timing for starting anticoagulation after an acute ischemic stroke related to non-valvular atrial fibrillation (AF) remains a challenge, especially in patients treated with systemic thrombolysis or mechanical thrombectomy. Purpose We aimed to assess the rates of early recurrence and major bleeding in patients with acute ischemic stroke and AF treated with thrombolytic therapy and/or thrombectomy who received oral anticoagulants for secondary prevention. Methods We combined the dataset of the RAF and the RAF-NOACs studies, which were prospective observational studies carried out from January 2012 to March 2014 and April 2014 to June 2016, respectively. We included consecutive patients with acute ischemic stroke and AF treated with either vitamin K antagonists (VKAs) or new oral anticoagulants (NOACs). Primary outcome was the composite of stroke, transient ischemic attack, symptomatic systemic embolism, symptomatic cerebral bleeding, and major extracerebral bleeding within 90 days from the inclusion. Results A total of 2,159 patients were included in the RAF and RAF-NOACs trials, of which 564 patients (26%) were treated with urgent reperfusion therapy. After acute stroke, 505 (90%) patients treated with reperfusion and 1,287 out of the 1,595 (81%) patients not treated with reperfusion started oral anticoagulation. Timing of starting oral anticoagulation was similar in reperfusion-treated and untreated patients (13.5±23.3 vs 12.3±18.3 days, respectively, p=0.287). At 90 days, the composite rate of recurrence and major bleeding occurred in 37 (7%) of patients treated with reperfusion treatment and in 139 (9%) of untreated patients (p=0.127). Twenty-four (4%) reperfusion-treated patients and 82 (5%) untreated patients had early recurrence while major bleeding occurred in 13 (2%) treated and in 64 (4%) untreated patients, respectively. Seven patients in the untreated group experienced both an ischemic and hemorrhagic event. Figure 1 shows the risk of early recurrence and major bleeding over time in patients treated and not treated with reperfusion treatments. The use of NOACs was associated with a favorable rate of the primary outcome compared to VKAs (Odd ratio 0.4, 95% Confidence Interval 0.3–0.7). Conclusions Reperfusion treatment did not influence the risk of early recurrence and major bleeding in patients with AF-related acute ischemic stroke who started anticoagulant treatment.
