They included 827 patients, followed median 6 years (range, 0.5–13) after procedure. Propensity score matching multivariable cox regression analyses were used relate OSA presence postprocedure AF stroke. found that was highly prevalent, observed 27% patients. had an ≈20% loss surgical treatment, which maintained years. significantly higher (10.4% versus 3%, P<0.0001) (12.6% 2.8%, at compared those OSA. Of stroke, only 20% new diagnosed. Although limited its design, highlights importance recognizing relation risk, even significant reduction, need evaluate cause other than AF. See p 2266.Delayed StrokeTalavera al, study, based on multicenter prospective reperfusion registry consecutive anterior circulation ischemic treated endovascular thrombectomy, frequency predictors delayed neurological improvement (DNI) treatment. using standard clinical guidelines thrombectomy. Early defined as decrease ≥4 points baseline National Institutes Health Scale Score >4, 24-hour 0 1 if <4.

Among 66.5% (n=323) good 90-day outcome. Baseline lower mRS, male sex, no fibrillation, Scale, distal artery occlusion, use intravenous thrombolysis. who experience likely symptomatic parenchymal hematoma-type intracranial hemorrhages, cerebral edema midline shift ≥5 mm, respiratory infection. This there is substantial proportion functional recovery following some treatable factors during hospitalization may modify occurrence improvement. 2210.Fluid-Attenuated ThrombectomyAoki studied 227 thrombectomy also brain magnetic resonance imaging before treatment changes fluid-attenuated inversion (FLAIR) signal hemorrhage outcome 3 months. FLAIR evaluated area diffusion-weighted restriction. Magnetic acquired similar time from symptom onset between positive (62%) negative groups (38%).

In analyses, negativity associated better (odds ratio, 2.10 [95%CI, 1.02–4.31]). positivity intracerebral type ≥1c (parenchymal hematoma) interacted so when both present less outcomes one present. observations suggest assessed prognostic value. However, whether can inform patient selection needs evaluation trials. 2232. Previous Back top Next FiguresReferencesRelatedDetailsRelated articlesRisk ApneaAhmed Dalmar, al.
