5. Interventional PFO closure. Consensus document of the German Workgroup of Interventional Cardiology (AGIK) of the German Cardiac Society (DGK) in cooperation with the German Society of Neurology (DGN) and the German Stroke Foundation (DSG)

Abstract

Almost every second patient with cryptogenic stroke has apatent foramen ovale (PFO). This consensus document firstly provides an evidence-based overview on the diagnostics of PFO, current studies, interventional closure, and medical therapy in terms of platelet aggregation inhibitors and anticoagulation. Secondly, the risk-benefit balance of interventional versus antithrombotic therapy with and without oral anticoagulants in patients with cryptogenic stroke and PFO is discussed based on recent findings of randomized controlled clinical trials (RCTs) and meta-analyses. Ultimately, the consented recommendations and levels thereof are indicated. The published data demonstrate the superiority of interventional PFO closure. There is asignificant reduction of recurrent strokes in patients with an interventional PFO closure device compared to medical therapy. The complication rate of the interventional therapy is low and particularly younger patients with cryptogenic stroke benefit from interventional PFO closure. In summary, interventional PFO closure is superior to medical treatment in patients with cryptogenic stroke aged <60years.

Abstract

Purpose: To determine the impact of collateral vessel status on clinical and imaging outcomes in patients undergoing endovascular therapy (EVT) for proximal middle cerebral artery (MCA) occlusion., Materials and Methods: There were 160 patients with proximal MCA occlusion at six centers in this institutional review board-approved multicenter EVT registry. Angiograms were analyzed at a blinded core laboratory, and collateral vessel status was assessed by using the American Society of Interventional and Therapeutic Neuroradiology (ASITN)/Society of Interventional Radiology (SIR) collateral vessel grading system, while reperfusion was assessed by using the Thrombolysis in Cerebral Infarction (TICI) scale. Good outcome was defined as a modified Rankin Scale score of 0-2 at follow-up. Binary logistic regression analysis was performed by using parameters with P < .2 in univariate analysis., Results: Good clinical outcome was attained in 62 (39%) of the 160 patients, and TICI 2b-3 reperfusion was achieved in 94 (59%) patients. Nineteen patients had ASITN/SIR collateral vessel grades of 0 or 1, 63 patients had a grade of 2, and 78 patients had grades of 3 or 4. Better collateral vessels were associated with higher reperfusion rates (21%, 48%, and 77% for ASITN/SIR grades of 0 or 1, 2, and 3 or 4, respectively; P < .001), a higher proportion of infarcts smaller than one-third of the MCA territory (32%, 48%, and 69% for ASITN/SIR grades of 0 or 1, 2, and 3 or 4, respectively; P < .001), and a higher proportion of good clinical outcome (11%, 35%, and 49% for ASITN/SIR grades of 0 or 1, 2, and 3 or 4, respectively; P = .007). At multivariable analysis, collateral vessel status independently predicted reperfusion, final infarct size, and clinical outcome. Within an onset-to-treatment time (OTT) of 0-3 hours, collateral vessel status predicted final infarct size and reperfusion. Within an OTT of 3-6 hours, it additionally predicted clinical outcome, with 53% of patients with ASITN/SIR grades of 3 or 4 having a good outcome, as compared with 0% of patients with grades of 0 or 1 and 27% of patients with a grade of 2 (P = .008)., Conclusion: In this patient population, collateral vessel status independently predicted the pivotal outcome parameters of reperfusion, infarct size, and clinical outcome. These data underscore the utility of patient selection for EVT on the basis of collateral vessel status.
