- Five-Year Outcome in Stroke Patients Submitted to ThrombolysisPublication . Machado, C; Pinho, J; Alves, JN; Santos, AF; Ferreira, MC; Abreu, MJ; Oliveira, L; Mota, J; Fontes, JR; Ferreira, CBACKGROUND AND PURPOSE: Little is known on long-term follow-up after thrombolysis in ischemic stroke patients because the majority of studies evaluated outcome at 3 to 12 months. We aimed to assess 5-year outcome after intravenous thrombolysis (IVT). METHODS: Cohort study based on the prospective registry of all consecutive ischemic stroke patients submitted to IVT in our Stroke Unit. Five-year outcome, including living settings, functional outcome, stroke recurrence, and mortality, was ascertained by telephonic interviews and additional review of clinical records. Multivariate analyses were performed to identify predictors of outcome and mortality. Excellent outcome was defined as modified Rankin scale 0 to 1. RESULTS: Five-year outcome was available for 155/164 patients submitted to IVT. At 5 years, 32.9% of patients had an excellent outcome (95% confidence interval (CI) =25.5-43.3) and mortality was 43.9% (95%CI=36.1-51.7). Increasing age (odds ratio =0.93, 95% CI =0.90-0.97) and increasing National Institute of Health Stroke Scale (NIHSS) 24 h after thrombolysis (odds ratio =0.81, 95% CI =0.74-0.90) were independently associated with a lower likelihood of an excellent 5-year outcome. Age (hazards ratio =1.07, 95% CI =1.03-1.11) and excellent functional outcome 3 months after thrombolysis (hazards ratio =0.28, 95%CI=0.12-0.66) were independently associated with mortality during follow-up. CONCLUSIONS: One third of ischemic stroke patients have excellent 5-year outcome after IVT. Younger age, lower NIHSS 24 h after IVT, and excellent 3-month functional outcome are independent predictors of excellent 5-year outcome.
- Hypertrophic olivary degeneration and cerebrovascular disease: movement in a triangle.Publication . Santos, AF; Rocha, S; Varanda, S; Pinho, J; Rodrigues, M; Ramalho Fontes, J; Soares-Fernandes, J; Ferreira, CHypertrophic olivary degeneration is a rare kind of trans-synaptic degeneration that occurs after lesions of the dentatorubro-olivary pathway. The lesions, commonly unilateral, may result from hemorrhage due to vascular malformation, trauma, surgical intervention or hypertension, tumor, or ischemia. Bilateral cases are extremely rare. This condition is classically associated with development of palatal tremor, but clinical manifestations can include other involuntary movements. We describe 2 cases: unilateral hypertrophic olivary degeneration in a 60-year-old man with contralateral athetosis and neurologic worsening developing several years after a pontine hemorrhage and bilateral hypertrophic olivary degeneration in a 77-year-old woman with development of palatal tremor, probably secondary to pontine ischemic lesions (small vessel disease).

- Orolingual angioedema after thrombolysis is not associated with insular cortex ischemia on pre-thrombolysis CTPublication . Pinho, J; Alves, JN; Oliveira, L; Pereira, S; Barros, JN; Machado, C; Amorim, JM; Santos, AF; Ribeiro, M; Ferreira, COrolingual angioedema (OA) is a well known early complication of treatment with alteplase in ischemic stroke patients. Our aim was to study risk factors for OA in these patients, namely insular cortex ischemia.

- Stroke and Cardiac Papillary Fibroelastoma: Mechanical Thrombectomy after Thrombolytic TherapyPublication . Santos, AF; Pinho, J; Ramos, V; Pardal, F; Rocha, J; Ferreira, CWe describe a case of a 34-year-old man with a sudden development of right hemiparesis and aphasia because of infarction of the left middle cerebral artery that was submitted to intravenous (IV) recombinant tissue plasminogen activator and mechanical thrombectomy. Transesophageal echocardiogram showed a small mass on the anterior leaflet of the mitral valve. Cardiac surgery was performed, and histological examination of the removed material was consistent with cardiac papillary fibroelastoma (CPF). Experience in using IV thrombolysis for the treatment of embolic stroke because of CPF is limited. To the best of our knowledge, only 3 patients are reported in literature in whom acute ischemic stroke and associated CPF were treated with thrombolytic therapy. A discussion of the efficacy of IV thrombolysis and the possible superiority of mechanical thrombectomy is included.
