    Abstract: 〈 i 〉 Background: 〈 /i 〉 The optimal management of patients with cryptogenic ischemic stroke found to have a patent foramen ovale (PFO) at diagnostic workup remains unclear. The aims of this observational multicenter study were to evaluate: (1) the risk of recurrent cerebrovascular events in patients with cryptogenic minor ischemic stroke or transient ischemic attack (TIA) and PFO who either underwent percutaneous PFO closure or received only medical treatment, and (2) the risk factors associated with recurrent events. 〈 i 〉 Methods: 〈 /i 〉 Consecutive patients (aged 55 years or less) with first-ever cryptogenic minor ischemic stroke or TIA and PFO were recruited in 13 Italian hospitals between January 2006 and September 2007 and followed up for 2 years. 〈 i 〉 Results: 〈 /i 〉 238 patients were included in the study (mean age 42.2 ± 10.0 years; 118 males); 117 patients (49.2%) received only antithrombotic therapy while 121 patients underwent percutaneous PFO closure (50.8%). Stroke as the qualifying event was more common in the medical treatment group (p = 0.01). The presence of atrial septal aneurysm and evidence of 20 bubbles or more on transcranial Doppler were more common in the PFO closure group (p = 0.002 and 0.02). Eight patients (6.6%) experienced a nonfatal complication during PFO closure. At the 2-year follow-up, 17 recurrent events (TIA or stroke; 3.6% per year) were observed; 7 of these events (2.9% per year) occurred in the percutaneous PFO closure group and 10 events (4.2% per year) in the medical treatment group. The rate of recurrent stroke was 0.4% per year in patients who underwent percutaneous closure (1 event) and 3.4% per year in patients who received medical treatment (8 events). On multivariate analysis, percutaneous closure was not protective in preventing recurrent TIA or stroke (OR = 0.1, 95% CI = 0.02–1.5, p = 0.1), while it was barely protective in preventing recurrent stroke (OR = 0.1, 95% CI = 0.0–1.0, p = 0.053). 〈 i 〉 Conclusions: 〈 /i 〉 The results of this observational, nonrandomized study suggest that PFO closure might be superior to medical therapy for the prevention of recurrent stroke. Periprocedural complications were the trade-off for this clinical benefit. Controlled randomized clinical trials comparing percutaneous closure with medical management are required.

    Abstract: The beneficial effect of intravenous thrombolytic therapy in patients with acute ischemic stroke attributable to internal carotid artery (ICA) occlusion remains unclear. The aim of this study was to evaluate the efficacy and safety of intravenous recombinant tissue-type plasminogen activator in these patients. Methods— ICARO was a case-control multicenter study on prospectively collected data. Patients with acute ischemic stroke and ICA occlusion treated with intravenous recombinant tissue-type plasminogen activator within 4.5 hours from symptom onset (cases) were compared to matched patients with acute stroke and ICA occlusion not treated with recombinant tissue-type plasminogen activator (controls). Cases and controls were matched for age, gender, and stroke severity. The efficacy outcome was disability at 90 days assessed by the modified Rankin Scale, dichotomized as favorable (score of 0–2) or unfavorable (score of 3–6). Safety outcomes were death and any intracranial bleeding. Results— Included in the analysis were 253 cases and 253 controls. Seventy-three cases (28.9%) had a favorable outcome as compared with 52 controls (20.6%; adjusted odds ratio (OR), 1.80; 95% confidence interval [CI], 1.03–3.15; P =0.037). A total of 104 patients died, 65 cases (25.7%) and 39 controls (15.4%; adjusted OR, 2.28; 95% CI, 1.36–3.22; P =0.001). There were more fatal bleedings (2.8% versus 0.4%; OR, 7.17; 95% CI, 0.87–58.71; P =0.068) in the cases than in the controls. Conclusions— In patients with stroke attributable to ICA occlusion, thrombolytic therapy results in a significant reduction in the proportion of patients dependent in activities of daily living. Increases in death and any intracranial bleeding were the trade-offs for this clinical benefit.
