Síndrome de reel como causa del mal funcionamiento del marcapasos: A propósito de un caso

Implantation of cardiac electronic devices is an increasingly common technique and the possibility of device dysfunction caused by electrode displacement should be taken into account. We describe the case of an 88-year-old patient with syncopes several months after pacemaker implantation in which a pacem...

Lead-DBS: an additional tool for stereotactic surgery

SUMMARY OBJECTIVE: Use Lead-DBS software to analyze stereotactical surgical outcome of an operated population and demonstrate that small target deviations do not compromise the stimulation of desired structures, even with small amperages. METHODS: Image exams of patients submitted to deep brain stimu...

Landmarks for the Location of the Subthalamic Nucleus Using Magnetic Resonance Imaging

Arq. bras. neurocir; 39 (4), 2020
Deep brain stimulation has become an option for advanced Parkinson’s disease treatment since the 1990s, but the first reports are from Benabid’s team, a French neurosurgeon, in the 1980s. The subthalamic nucleus (STN), more specifically its dorsolateral portion, is the most commonly stimulated brain ...

Safety of transcranial direct current stimulation in a patient with deep brain stimulation electrodes

Arq. neuropsiquiatr; 77 (3), 2019
ABSTRACT Background: Transcranial direct current stimulation (tDCS) has been investigated in movement disorders, making it a therapeutic alternative in clinical settings. However, there is still no consensus on the most appropriate treatment protocols in most cases, and the presence of deep brain stimul...

Minimally Invasive Epicardial Pacemaker Implantation in Neonates with Congenital Heart Block

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Few studies have characterized the surgical outcomes following epicardial pacemaker implantation in neonates with congenital complete atrioventricular block (CCAVB). Objective: This study sought to assess the long-term outcomes of a minimally invasive epicardial approach using a su...

Bereitschaftspotential preceding eyelid blinks in Parkinson's disease

Arq. neuropsiquiatr; 75 (8), 2017
ABSTRACT The Bereitschaftspotential (BP) is a negative wave observed in EEG retrograde averaging, preceding a motor act. The objective was to study the BP preceding voluntary eyelid blinks in Parkinson's disease (PD) patients during off and on phases of levodopa. Methods Ten PD patients in stages 1 and...

Interferência eletromagnética documentada em monitor de eventos implantável

Monitores de eventos implantáveis estão cada vez mais presentes em nossa realidade. Este relato tem como foco o registro eletrocardiográ- fico obtido por monitor de eventos implantável durante ressonância magnética de paciente com síncope de repetição. O registro demonstra traçado interpretado ...

Rotura iatrogénica de electrodos de marcapasos permanente en la realización de esternotomía media: presentación de un caso

Med. UIS; 29 (3), 2016
RESUMEN La esternotomía media continúa siendo el gold-standart de abordaje quirúrgico en cirugía cardiaca. Aún realizada correctamente, la apertura media del esternón presenta complicaciones en el 1-5% de los casos que varían en su gravedad desde la infección de la herida quirúrgica a la lesión...
