Portable gamma-camera for the diagnosis of brain death diagnosis

ConclusionsA portable gamma-camera could be a useful and feasible tool for the diagnosis of BD.ResumenObjetivoEvaluar la factibilidad del empleo de la minigammacámara portátil Sentinella®, para el diagnóstico de muerte encefálica (ME).DiseñoEstudio observacional, prospectivo, de factibilidad.ÁmbitoUnidad de cuidados intensivos de un hospital de tercer nivel.PacientesDesde enero a diciembre de 2017 se registraron de forma consecutiva los pacientes mayores de edad que tras su ingreso en unidad de cuidados intensivos fueron diagnosticados de ME según criterios clínicos.IntervencionesEl procedimiento se realizó a la cabecera del paciente tras la administración intravenosa de tecnecio 99 metaestable-hexametil-propilen-amino-oxima. La ausencia de perfusión a nivel de hemisferios cerebrales y fosa posterior se describía como patrón compatible con ME. Se correlacionó el diagnóstico con doppler transcraneal y/o electroencefalograma.ResultadosCincuenta y seis pacientes presentaron exploración física compatible con ME. Un 66,1% fueron hombres con una mediana de edad de 60 (RIQ: 51-72) años. La causa más frecuente que precipitó la ME fue el ictus hemorrágico en el 48,2% (27) seguido por traumatismo craneoencefálico grave en el 30,4% (17), ictus isquémico en el 10,7% (6) y encefalopatía anóxica tras parada cardio...

AbstractLeft ventricular assist devices (LVAD) are widely applied for patients with severe heart failure as a bridge to heart transplantation as well as destination therapy. Patients with implanted LVAD have an increased risk of cerebral thrombosis and computed tomographic perfusion (CTP) has the potential to be performed for early diagnosis and treatment of acute ischemic stroke (AIS), including interventional thrombectomy. Here, we report our series of CTP examination in patients having suspected AIS after LVAD implantation. We retrospectively investigated 33 contrast-enhanced CTPs from January 2017 to December 2018 whic...

Abstract Regional cold perfusion and hemoglobin-based oxygen carrier administration both exert neuroprotective effects against cerebral ischemia reperfusion injury. We herein investigated whether the combination of these two therapies leads to stronger neuroprotective effects. Combination therapy was performed with the regional perfusion of cold HemoAct, a core-shell structured hemoglobin-albumin cluster, in a rat transient middle cerebral artery occlusion model. The effects of combination therapy, the intra-arterial administration of 10°C HemoAct (10H) initiated at the onset of reperfusion, were compared with...

In this study, 5% of VF arrest was due to PE: V fib is initial rhythm in PE in 3 of 60 cases. On the other hand, if the presenting rhythm is PEA, then pulmonary embolism is likely.  When there is VF in PE, it is not the initial rhythm, but occurs after prolonged PEA renders the myocardium ischemic.--Another study by Courtney and Kline found that, of cases of arrest that had autopsy and found that a presenting rhythm of VF/VT had an odds ratio of 0.02 for massive pulmonary embolism as the etiology, vs 41.9 for PEA.    ===================================MY Comment by KEN ...

Abstract BACKGROUND: Early neurologic deterioration (END) may occur in patients with anterior circulation ischemic stroke (ACIS) after receiving endovascular treatment (EVT). Hemodynamic insufficiency, re-occlusion, and post-re-canalization hyper-perfusion are likely to play a critical role in END. We hypothesized that hemodynamic changes can predict END in patients with ACIS post-successful EVT using trans-cranial Doppler (TCD). METHODS: We utilized a prospectively maintained database of ACIS patients treated with EVT between September 2016 and June 2018 at the Xuanwu Hospital, Capital Medical University. TC...

This study aims to reveal factors associated with HT in patients with ischemic onset manifestation and to assess the outcome of these patients.Methods: A total of 683 surgically managed patients with onset ischemic manifestation were included. The clinical variables of the HT and non-HT groups were compared, and risk factors were analyzed using logistic regression analysis. Recurrent stroke events (including hemorrhagic and ischemic) during the follow-up were documented. The cumulative incidence rate of stroke events was generated via Kaplan–Meier survival analysis. Outcomes were compared between HT and non-HT groups...

Conclusion: Direct compression of ICA is rare complication of pituitary apoplexy, which caused cerebral ischemia. Conventional angiography should be necessary for accurate diagnosis and prompt surgical decompression should be the treatment of choice. PMID: 32494388 [PubMed]

Conclusion: Compared to pCT, DECT within 36 h after IV thrombolysis for acute ischemic stroke, changes the radiological diagnosis of post-treatment ICH to “CS only” in a small proportion of patients. Studies are warranted of whether the altered radiological reports have an impact on patient management, for example initiation timing of antithrombotic secondary prevention.

Objective: To evaluate clinical and radiological outcomes after revascularization of hemorrhagic moyamoya disease (MMD).Materials and Methods: We retrospectively collected patients with hemorrhagic MMD who received revascularization from January 2011 to June 2018 at a high-volume stroke center. Rebleeding, ischemic stroke, modified Rankin Scale (mRS) and death after revascularization were used to evaluate long-term clinical outcome. Poor neurological outcome was defined as a mRS>2. The changes of original and revascularization collaterals were used to evaluate radiological outcome. The clinical and radiological outcomes...

Abstract RATIONALE: Large decreases in PaCO2 that occur when initiating extracorporeal membrane oxygenation (ECMO) in patients with respiratory failure may cause cerebral vasoconstriction and compromise brain tissue perfusion. OBJECTIVES: To determine if the magnitude of PaCO2 correction upon ECMO initiation is associated with an increased incidence of neurological complications in patients with respiratory failure. METHODS: We conducted a multicenter international retrospective cohort study using the Extracorporeal Life Support Organization (ELSO) Registry, including adults with respiratory failure on a...
