Abdominal trauma.

Traumatic injuries are the leading cause of death in people aged<45 years, and abdominal trauma is a source of significant morbidity and mortality and high economic costs. Imaging has a fundamental role in abdominal trauma, where CT is a fundamental tool for rapid, accurate diagnosis that will be key for patients' clinical outcomes.

Mortalidad en pacientes con hemorragia intracerebral asociada a anticoagulación oral. Eficacia de un protocolo de reversión y seguimiento clínico (proyecto HIC-ACO) / Mortality in patients with intracerebral haemorrhage associated with oral anticoagulation. Efficacy of a reversal protocol and clinical follow-up (ICH-OAC project)

Introducción: La hemorragia intracerebral espontánea asociada a anticoagulantes orales (HIC-ACO) presenta una elevada mortalidad. La aparición de nuevos fármacos anticoagulantes y protocolos de reversión aumenta el interés por esta entidad. Objetivos: El objetivo principal es determinar la tasa de mortalidad en pacientes con HIC-ACO (precoz, hospitalaria, global) en nuestra área sanitaria y analizar las principales variables relacionadas. El objetivo secundario es determinar la eficacia de las terapias de reversión de la anticoagulación (TRA), reflejada por la expansión radiológica del hematoma y el pronóstico funcional. Pacientes y métodos: Estudio prospectivo observacional que introdujo un protocolo dirigido al manejo de pacientes con HIC-ACO. Incluyó medidas generales y neuromonitorización, administración individualizada de TRA, tomografía craneal y seguimiento durante seis meses. Se recogieron los fármacos prescritos en el área durante este período, mortalidad y pronóstico funcional. Se diseñó un estudio bivariante y regresión logística para investigar variables relacionadas con la mortalidad. Resultados: Se incluyó a 49 pacientes durante tres años; de ellos, un 71,4% recibió TRA. La mortalidad fue del 16,3% (primeras 24 horas), el 53,1% (ingreso) y el 61,2% (180 días). Se observó una menor supervivencia entre pacientes con puntuaciones basales mayores en la National Institutes of Healt Stroke Scale (NIHSS) (p < 0,0001), valor de creatinina (p = 0,02), índice internacional normalizado (p = 0,048), volumen hemorrágico (p = 0,008), hidrocefalia (p = 0,015) y toma de acenocumarol (p = 0,030). Los pacientes que no recibieron TRA tuvieron una mayor mortalidad precoz (p = 0,003). La única variable relacionada con la mortalidad global de forma independiente fue la puntuación en la NIHSS basal (odds ratio = 1,282; intervalo de confianza al 95%: 1,023-1,608; p = 0,031)...(AU)

Introduction: Spontaneous intracerebral haemorrhage associated with oral anticoagulants (ICH-OAC) has a high mortality rate. The emergence of new anticoagulant drugs and reversal protocols increases interest in this entity. Objectives: The main objective is to determine the mortality rate in patients with ICH-OAC (early, in-hospital, global) in our health area and to analyse the main variables related to it. The secondary objective is to determine the efficacy of anticoagulation reversal therapies (ART) as reflected by radiological expansion of the haematoma and the functional prognosis. Patients and methods: A prospective observational study that introduced a protocol aimed at the management of patients with ICH-OAC. It included general measures and neuromonitoring, individualised administration of ART, cranial tomography and a six-month follow-up. Data on the drugs prescribed in the area during this period, mortality and functional prognosis were collected. A bivariate and logistic regression study was designed to investigate mortality-related variables. Results: Forty-nine patients were included over three years; of these, 71.4% received ART. Mortality was 16.3% (first 24 hours), 53.1% (admission) and 61.2% (180 days). Lower survival was observed among patients with higher baseline scores on the National Institutes of Health Stroke Scale (NIHSS) (p < 0.0001), creatinine value (p = 0.02), International Normalised Index (p = 0.048), bleeding volume (p = 0.008), hydrocephalus (p = 0.015) and acenocoumarol intake (p = 0.030). Patients who did not receive ART had a greater rate of early mortality (p = 0.003). The only variable independently related to overall mortality was the baseline NIHSS score (odds ratio = 1.282; 95% confidence interval: 1.023-1.608; p = 0.031)...(AU)

CONCLUSIONS: ICH-OAC has a high mortality rate, related to the use of acenocoumarol and regardless of the initial clinical situation. A lower rate of early mortality was found among patients who received ART.

Cerebrovascular disease in patients with COVID-19: neuroimaging, histological and clinical description.

Since the appearance of the first case of coronavirus disease 2019 (COVID-19) a pandemic has emerged affecting millions of individuals worldwide. Although the main clinical manifestations are respiratory, an increase in neurological conditions, specifically acute cerebrovascular disease, has been detected. We present cerebrovascular disease case incidence in hospitalized patients with SARS-CoV-2 infection. Patients were confirmed by microbiological/serological testing, or on chest CT semiology. Available data on co-morbidity, laboratory parameters, treatment administered, neuroimaging, neuropathological studies and clinical evolution during hospitalization, measured by the modified Rankin scale, were analysed. A bivariate study was also designed to identify differences between ischaemic and haemorrhagic subtypes. A statistical model of binary logistic regression and sensitivity analysis was designed to study the influence of independent variables over prognosis. In our centre, there were 1683 admissions of patients with COVID-19 over 50 days, of which 23 (1.4%) developed cerebrovascular disease. Within this group of patients, cerebral and chest CT scans were performed in all cases, and MRI in six (26.1%). Histological samples were obtained in 6/23 cases (two brain biopsies, and four arterial thrombi). Seventeen patients were classified as cerebral ischaemia (73.9%, with two arterial dissections), five as intracerebral haemorrhage (21.7%), and one leukoencephalopathy of posterior reversible encephalopathy type. Haemorrhagic patients had higher ferritin levels at the time of stroke (1554.3 versus 519.2, P = 0.004). Ischaemic strokes were unexpectedly frequent in the vertebrobasilar territory (6/17, 35.3%). In the haemorrhagic group, a characteristic radiological pattern was identified showing subarachnoid haemorrhage, parieto-occipital leukoencephalopathy, microbleeds and single or multiple focal haematomas. Brain biopsies performed showed signs of thrombotic microangiopathy and endothelial injury, with no evidence of vasculitis or necrotizing encephalitis. The functional prognosis during the hospital period was unfavourable in 73.9% (17/23 modified Rankin scale 4-6), and age was the main predictive variable (odds ratio = 1.5; 95% confidence interval 1.012-2.225; P = 0.043). Our series shows cerebrovascular disease incidence of 1.4% in patients with COVID-19 with high morbidity and mortality. We describe pathological and radiological data consistent with thrombotic microangiopathy caused by endotheliopathy with a haemorrhagic predisposition.

Embolismo arterial gaseoso paradójico tras una herida incisa craneal directa / Paradoxical arterial gas embolism following a direct incisive injury to the skull

Introducción. El embolismo arterial gaseoso se define como la presencia de aire en la circulación arterial. Se trata de una causa extremadamente rara de ictus que se ha descrito en multitud de escenarios clínicos, generalmente relacionados con procesos yatrógenos. Se aporta un caso clínico en el que el embolismo arterial gaseoso sucedió tras un traumatismo craneoencefálico, y se revisan los aspectos más relevantes del diagnóstico y la etiopatogenia. Caso clínico. Mujer de 52 años que presentaba herida incisa craneofacial tras una agresión con un hacha. La tomografía computarizada inicial objetivó fractura en los arcos cigomático, esfenoidal y maxilar izquierdos, así como neumoencéfalo en los senos cavernosos y el canal carotídeo derecho. Una hora más tarde, la paciente mostró un déficit neurológico hemisférico derecho, por lo que se solicitó de forma urgente una nueva tomografía computarizada craneal con estudio vascular multimodal, que objetivó la movilización del neumoencéfalo y descartó una oclusión arterial de gran vaso. Un estudio de shunt mediante Doppler transcraneal y ecocardiografía comprobó la presencia de un foramen oval permeable como causa de comunicación arteriovenosa que justificaba un embolismo arterial gaseoso. La tomografía computarizada de control a las 48 horas confirmó la aparición de una lesión isquémica parietal derecha. Conclusión. En este caso queda reflejada la presencia simultánea de aire en la circulación cerebral arterial y venosa y la comunicación periférica a través de un foramen oval permeable. Este mecanismo de producción está escasamente documentado en la bibliografía

Introduction. An arterial gas embolism is defined as the presence of air in the arterial circulation. This is an extremely rare cause of stroke that has been described in a multitude of clinical scenarios, generally related to iatrogenic processes. A clinical case is reported in which the arterial gas embolism occurred after a traumatic brain injury, and the most relevant aspects of diagnosis and aetiopathogenesis are reviewed. Case report. We report the case of a 52-year-old woman with an open craniofacial wound resulting from an attack with an axe. The initial CT scan found fractures in the left zygomatic, sphenoidal and maxillary arches, as well as pneumocephalus in the cavernous sinuses and the right carotid canal. One hour later, the patient showed a neurological deficit in the right hemisphere, and so a new cranial computed tomography scan with multimodal vascular study was urgently requested, which revealed the mobilisation of the pneumocephalus and ruled out a large vessel arterial occlusion. A shunt study using transcranial Doppler and echocardiography showed the presence of a patent foramen ovale to be the cause ofarteriovenous communication that justified an arterial gas embolism. The follow-up CT scan at 48 hours confirmed the appearance of a right parietal ischaemic lesion. Conclusion. This case reflects the simultaneous presence of air in the arterial and venous circulation of the brain, as well as the peripheral communication through a patent foramen ovale. This production mechanism is poorly documented in the literature
