    Carotid artery dissection: Endovascular treatment. Report of 12 patients
    (WILEY-LISS, 2008) Fava, Mario; Meneses, Luis; Loyola, Soledad; Tevah, Jose; Bertoni, Hernan; Huetel, Isidro; Mellado, Patricio
    Objective: The purpose of this article is to report our experience with endovascular treatment of internal carotid artery (ICA) dissection with the use of stents. Background: Carotid Dissection is an important cause of ischemic stroke in young and middle-aged patients. There are some patients in whom invasive management is recommended. Methods: Twelve patients (eight females, four males), mean age of 50 years (range 3580 years) with ICA dissection, were treated with the endovascular approach during a 24-month period. Patients included in this study underwent magnetic resonance (MR) and digital subtraction angiography (DSA) for diagnosis. Over this time period, 162 patients with ICA dissections were seen at our institution. Indications for endovascular treatment were: recurrent ischemic events despite adequate anticoagulant treatment in seven cases, contraindication to anticoagulation in four cases, and one case with significant mismatch between diffusion and perfusion weighted MR. Eleven dissections were spontaneous and one was traumatic. The follow-up was performed clinically with Doppler ultrasound (US) and MR at 6, 12, and 24 months. Results: Stent deployment was successful in all cases. Acute symptoms were resolved in 66.7% of patients. No patients deteriorated their neurological status. There were no new clinical events, stent stenosis or occlusion on 24 months follow-up. Conclusion: Our results showed an excellent clinical outcome of the treated patients. This suggests promising results with the use of endovascular treatment in selected patients. (c) 2008 Wiley-Liss, Inc.

    Natriuretic peptide type-B can be a marker of reperfusion in patients with pulmonary thromboembolism subjected to invasive treatment
    (2012) Andresen, Max; Gonzalez, Alejandro; Mercado, Marcelo; Diaz, Orlando; Meneses, Luis; Fava, Mario; Cordova, Samuel; Castro, Ricardo
    This study was intended to investigate changes in cardiac biomarkers and pulmonary hemodynamic effects of invasive treatment in patients with intermediate-risk (hemodynamic stability with evidence of right ventricle dysfunction and/or myocardial injury) pulmonary embolism. Also, to also evaluate if natriuretic peptide type-B (NT-proBNP) plasma levels are associated with right ventricle function and pulmonary arterial pressures. Interventional study: Fourteen normotensive adult patients with acute and radiologically massive pulmonary embolism plus positive biomarkers and evidences of right ventricle dysfunction underwent invasive pulmonary angiography for invasive treatment consisting on mechanical thrombus fragmentation and catheter-directed intrathrombus thrombolysis. Angiography was repeated after 12-24 h to reevaluate perfusion status. Plasma biomarkers were monitored before and 8-h after intervention. Biomarkers were initially elevated in all patients. Eleven patients (78.6%) exhibited significant angiographic reperfusion. NT-proBNP and mean pulmonary arterial pressure decreased significantly in all of them [3693 (1803, 8862) to 1951 (1309, 7918) pg/ml; P = 0.008) and 40.0 (24.0, 46.0) to 22.0 (14.0, 27.0) mmHg; P = 0.003, respectively]. No significant variation was observed in troponin-T levels. In patients with high-risk pulmonary embolism, NT-proBNP plasma levels experience rapid and significant reduction after successful invasive treatment. In pulmonary embolism, serial measurements of NT-proBNP could be useful as a tracking tool to assess the success or failure of the thrombolytic treatment.
