Single puncture approach guided by transesophageal echocardiography for atrial ...
Oliveira, M; Sousa, L; Trindade, A; da Silva, NBackground: Atrial septal defect (ASD) is associated with a risk of developing atrial fibrillation (AF) higher than in the general population, even after percutaneous or surgical septal closure. Catheter ablation is an effective treatment strategy for preventing recurrences and reducing the AF burden. However, electrophysiologists are faced with technical difficulties and the risk of complications with the left...

Diurnal variability of inner-shelf circulation in the lee of a cape under upwel...
Lamas, L; Peliz, A; Dias, J; Oliveira, PB; Angélico, MM; Castro, JJ; Fernandes, JN; Trindade, A; Cruz, TThe nearshore circulation in the lee of a cape under upwelling conditions was studied using in-situ data from 3 consecutive summers (2006–2008). Focus was given to a period between 20 July and 04 August 2006 to study the diurnal variability of the cross-shelf circulation. This period was chosen because it had a steady upwellingfavourable wind condition modulated by a diurnal cycle much similar to sea breeze. Th...
Central neurocytomas.
Pimentel, J; Nunes, J F; Távora, L; Trindade, A; Ferreira, A GCentral neurocytomas are a well-characterized group of neuronal tumors usually arising in the supratentorial ventricular cavities. We describe the anatomical and clinical study of seven of these neoplasms. Patients were in the first four decades of life, and tumors were usually located in one of the lateral ventricles. Surgical resection was subtotal in 6 cases. Light microscopic examination revealed predominan...
Neuroradiology in the physiopathologic diagnosis of subarachnoid hemorrhage--ce...
Campos, J G; Gomes, L B; Almeida, A; Fernandes, A; Coutinho, D; Afonso, J G; Ferro, J; Trindade, A; Antunes, J LThe clinical importance of the cerebral aneurismatic lesion in well known. In Portugal we still do not have reliable statistics regarding the occurrence of the subarachnoid hemorrhage, however we can make a comparison through Kassel's and Drake's studies where they refer that annually 28,000 North-Americans suffer from subarachnoid hemorrhage attributed to the rupture of the cerebral aneurysm. This is a clinica...
Nimodipine in subarachnoid hemorrhage.
Ferro, J M; Canhão, P; Melo, T P; Campos, J G; Trindade, A; Antunes, J LThe efficacy of nimodipine in decreasing mortality and morbidity of subarachnoid haemorrhage (HSA) is evaluated in 51 patients admitted to the Neurological and Neurosurgery Departments of the Santa Maria Hospital. Reductions of 2 x (0.65, 6.39) of the incidence of ischemia in the total group and of 2.1 x (0.58, 7.79) of mortality in the sub-group with initial severity of less than 4 points of the Hunt score wer...
Intravascular therapy of giant cerebral aneurysm.
Campos, J G; Gomes, L B; Almeida, A; Coutinho, D; Pereira, R; Antunes, J L; Trindade, A; Baeta, E; Pavão, IThe endovascular therapy in cerebral aneurysms has met significant technical progress, specially related with new microcatheters and different types of detachable balloons. Reviewing seven cases of giant cerebral aneurysms treated by intra arterial approach, the authors present their results pointing out and discussing the different angiosurgical therapy that can actually be used.; The endovascular therapy in c...
