RESUMO

PURPOSE: Diagnostic cerebral digital subtraction angiography (DSA) is an invasive examination that involves catheterization of the major supra-aortic arterial trunks and evaluation of intracranial vessels for diagnostic purposes. Although considered the gold standard method for investigating cerebrovascular diseases, DSA carries measurable and potentially serious complication rates. This report describes the frequency of neurological and non-neurological complications of DSA performed in five hospitals in the state of São Paulo, Brazil, and analyzes them in different disease subgroups. It has a special focus on thromboembolic cerebral complications. METHODS: We retrospectively reviewed clinical records of all adult patients who underwent DSAs between January 2019 and December 2022. Demographic variables, DSA reports, CT/MRI reports, and clinical follow-up notes were reviewed. RESULTS: Twenty-four patients experienced some type of complication among 2,457 diagnostic DSAs (0.97%). Thromboembolic complications were recorded in 9 patients (0.36%), and access site hematomas larger than 5 cm were registered in six patients (0.24%). There was a statistical trend for thromboembolic complications in patients with cervical and/or intracranial atherosclerosis (p = 0.07), but age was not associated with them (p = 0.93). Patients who received heparin had lower rates of embolic complications than those who did not receive it, but there was no statistically significant difference (p = 0.17). Intravenous administration of heparin showed a trend toward significance with groin hematoma (p = 0.10). CONCLUSION: Diagnostic catheter DSAs have low complication rates.

RESUMO

While neurologic complications are frequently reported among patients with COVID-19 in the general population, they are unknown in pregnant women. This paper summarizes the case reports of pregnant women with confirmed SARS-CoV-2 infection plus a specified neurologic diagnosis. Until November 2021, 18 case reports were found. Both the central and peripheral nervous systems were equally affected: delirium (n = 1), posterior reversible encephalopathy syndrome (n = 4), cerebrovascular disease (n = 2), acute cerebral demyelinating disease (n = 1), acute necrotizing encephalopathy (n = 1), Guillain-Barré syndrome (n = 5), including one patient who also had vestibular neuritis, Bell's palsy (n = 3), and rhabdomyolysis (n = 1). The median maternal age was 32.5 (25-35) years, the median gestational age was 34 (30-36.5) weeks, and 38.9% presented previous medical conditions. Respiratory symptoms were reported in 76.5%, and 76.5% received immunotherapies to treat the COVID-19 or the neurologic complications. Half the women required admission to ICU and, more often, were those with central nervous system involvement (77.8% vs. 22.2%; Chi-square test, p = .018). For 64.7% of women, the most common method of delivery was surgical, although just one case was due to the neurologic complication. There were reports of one spontaneous abortion, two fetal deaths, and no maternal deaths. Only one case presented a poor neurologic outcome. It is possible that our findings are underestimated, considering that there are thousands of reports regarding neurologic complications in the general population with COVID-19.

RESUMO

Neurological complications in orthotopic heart transplantation represent a major cause of morbidity and mortality despite successful transplantation. The aim of our study was to evaluate neurological complications on the outcome of patients with heart transplantation. We retrospectively studied 193 adult patients (aged = 18 years) who underwent heart transplant at Hospital Italiano in Buenos Aires from November 2014 to August 2018. We evaluated demographic and clinical vari ables and outcome of patients with and without neurological complications. We included 193 patients with a mean age of 51 ± 12 years of which 74% (n = 143) were men. The two most frequent causes that led to heart transplantation were idiopathic cardiomyopathy in 34% (n = 65) and ischemic cardiomyopathy in 29% (n = 56). Hemodynamic instability was present at the moment of transplant in 92% (n = 176) of the cases. Central neurological complications in the first week post-transplant occurred in 12% (n = 23). The most frequent were: encephalopathy (5%), subdural hematoma (2%), subarachnoid hemorrhage (2%), seizures (2%) and ischemic stroke (1%). Peripheral neuropathy was observed in 4% of cases. Hospital mortality was 11% (n = 22) and 88% (n = 170) was discharged at home. Those who presented central neurological complications had higher in-hospital mortality compared to those who did not (32% vs. 9%, p = 0.002).


Las complicaciones neurológicas posteriores al trasplante cardíaco representan una causa importante de morbimortalidad. La meta del presente estudio fue evaluar las complicaciones neurológicas (CN) en la evolución clínica de pacientes sometidos a trasplante cardíaco. Se evaluaron retrospectivamente todos los trasplantados cardíacos en el Hospital Italiano de Buenos Aires de noviembre del 2014 hasta agosto del 2018. Se evaluaron variables demográficas y clínicas, y se compararon entre los pacientes con y sin CN. Se incluyeron 193 adultos (edad = 18 años). La edad media fue de 51 ± 12 años, y 74% (n = 143) fueron varones. Las dos causas más frecuentes que llevaron a la indicación de trasplante fueron la miocardiopatía idiopática en 34% (n = 65) y la isquémica en 29% (n = 56). El 92% (n = 176) presentó inestabilidad hemodinámica al momento del trasplante. El 12% (n = 23) presentó CN centrales en la primer semana post-trasplante. Las más frecuentes fueron encefalopatía (5%), hematoma subdural (2%), hemorragia subaracnoidea (2%), convulsiones (2%), y accidente cerebrovascular isquémico (1%). En 4% se observó neuropatía periférica. La mortalidad hospitalaria fue del 11%, y 88% de los pacientes fueron dados de alta a domicilio. Los que presentaron CN centrales tuvieron mayor mortalidad intrahospitalaria en comparación a quienes no las presentaron (32% vs. 9%, p = 0.002).

RESUMO

The disease caused by each of the four serotypes of dengue virus (DENV) have plagued humans since last century. Symptoms of dengue virus (DENV) infection range from asymptomatic to dengue fever (DF) to severe dengue disease (SDD). One third of the world's population lives in regions with active urban DENV transmission, and thousands of serologically naïve travelers visit these areas annually, making a significant portion of the human population at risk of being infected. Even though lifelong immunity to the homotypic serotype is achieved after a primary DENV infection. Heterotypic DENV infections may be exacerbated by a pre-existing immune memory to the primary infection and can result in an increased probability of severe disease. Not only, age, comorbidities and presence of antibodies transferred passively from dengue-immune mother to infants are considered risk factors to dengue severe forms. Plasma leakage and multiple organ impairment are well documented in the literature, affecting liver, lung, brain, muscle, and kidney. However, unusual manifestation, severe or not, have been reported and may require medical attention. This review will summarize and discuss the increasing reports of unusual manifestations in the clinical course of dengue infection.

RESUMO

The clinical focus after kidney transplantation often is centered on graft function. However, neurologic complications are a common, significant, and under-recognized contributor to patient morbidity and mortality. Neurologic syndromes can arise through exacerbation of pre-existing conditions or can be newly acquired in the setting of increased risk of infection and drug toxicity after transplantation. We present a comprehensive review of neurologic complications after kidney transplantation.

RESUMO

Neurologic alterations form part of the classical manifestations of megaloblastic anemias, with pernicious anemia being the prototype. Subacute combined degeneration of the spinal cord with involvement of the posterior and lateral columns, axonal or demyelinating sensorimotor neuropathy, Lhermitte's syndrome, neuropsychiatric manifestations and degeneration of the autonomic innervation of the bladder and the Auerbach and Meissner plexuses being among the most important features. Of great importance is the possible absence of macrocytosis or even anemia in cases of neurologic manifestations. Otherwise, the multisegmentation of neutrophils may be an important indication for the correct diagnosis, particularly when the serum levels of vitamin B12 and methylmalonic acid are not available.

RESUMO

Una de las más importantes pero la menos común de las manifestaciones de enfermedad autoinmune la constituye la vasculitis, la cual modifica la historia de la enfermedad, dependiendo del órgano afectado. Esta revisión incluye las más importantes manifestaciones y complicaciones de los sistemas nerviosos central y periférico que se desarrollan por vasculitis en las enfermedades reumáticas, ya sea como una primera manifestación de enfermedad o como acompañante de enfermedad sistémica. También hacemos una revisión de la inmunopatogénesis, los principales hallazgos radiológicos, hallazgos en las biopsias de tejido cerebral o de nervio periférico, en las biopsias de músculo, con los posibles diagnósticos diferenciales conocidos.


The vasculitis is one of the most common manifestations of autoimmune diseases, it will change the medical evolution depending on the affected organ. This review includes the most important manifestations and complications in the central and peripheral nervous system, due to vasculitis developed in the setting of rheumatic diseases, as a primary manifestation or as a part of other symptoms, as well. Also, an up date in immunopathogenesis, radiology, peripheral and central nervous biopsy, muscle biopsy findings, and differential diagnosis is made.
