【Abstract】
Background Instability of atherosclerotic plaques is associated with the occurrence of stroke. Microembolic signals (MESs) are anindicator of unstable plaque. A relationship between plasma osteoprotegerin (OPG) and ischemic stroke has already beenidentifified. The aim of this study was to investigate whether plasma OPG levels have a relationship with MESs and to evaluatethe feasibility of OPG as a biomarker of stroke severity and occurrence of MESs.
Methods Our study consisted of 127 patientswith large artery atherosclerosis stroke and 56 controls. Patients were classifified into subgroups based on stroke severity andthe occurrence of MESs. MES-monitoring was performed for 60 min using transcranial Doppler 【Delica EMS-9EB】within 72 h of strokeonset. Stroke severity at admission was assessed by the National Institutes of Health Stroke Scale.
Results Plasma OPGlevels were signifificantly associated with stroke, MESs, and stroke severity at admission (adjusted OR [95% CI]: 1.002[1.001–1.003] p < 0 001; 1.002 [1.001–1.003] p = 0 001; 1.001 [1.000–1.002] p = 0 028). When plasma OPG levels were used todetermine the stroke severity, the area under the receiver-operating characteristic curve (AUC) was 0.734 (95% CI: 0.625-0.843)based on a cutoffff value of 1998.44 pg/ml; the sensitivity and specifificity of this test were 80.6% and 65.6%, respectively.Furthermore, when the levels of OPG were used to distinguish the presence of MESs, the AUC was 0.766 (95% CI: 0.672-0.860);the cutoffff value was 2107.91 pg/ml. The sensitivity of this cutoffff value was 68.8% and the specifificity was 73.7%.
Conclusions Plasma OPG levels correlate with stroke severity and the occurrence of MESs.

OBJECTIVES: Reducing the rate of postoperative stroke after cardiac surgery remains challenging, especially in patients with occlusive cerebrovascular disease. Angioplasty in all patients with high-grade carotid artery stenosis has not been shown to be effective in reducing thepost-surgical stroke rate. In this study, we present the initial results of a different approach using selective carotid angioplasty only inpatients with poor intracranial collaterals.
METHODS: We conducted a single-centre study to assess the safety of this procedure. The postangioplasty complication rate of the studygroup was compared to that of patients who were scheduled for symptomatic carotid artery angioplasty. To determine the effectiveness ofthis procedure, the post-cardiac surgery complication rate of the study group was compared with that of the matched case controls.
RESULTS: Twenty-two patients were treated with selective carotid angioplasty without developing persistent major neurological complications. All patients except 1 patient subsequently underwent surgery without developing persistent major neurological disabilities. Twopatients died of cardiogenic shock within 30 days.
CONCLUSIONS: Selective carotid angioplasty prior to cardiac surgery in patients with a presumed high risk of stroke was relatively safeand effective in this study group. Although this strategy does not prevent stroke in these high-risk patients, data suggest that this approachshifts the postoperative type of stroke from a severe haemodynamic stroke towards a minor embolic stroke with favourable neurologicaloutcomes. Larger studies are needed to determine whether this strategy can effectively eliminate the occurrence of haemodynamic strokeafter cardiac surgery.
