Re: Comparison of the Surgical Approaches for Frontal Traumatic Intracerebral Hemorrhage
( Luis Rafael Moscote-salazar ),( Ezequiel Garcia-ballestas ),( Pradeep Chouksey ),( Amit Agrawal ) 대한외상학회 2020 大韓外傷學會誌 Vol.33 No.1
Dear editor, in an interesting article, Park et al. [1] report their experience with minimally invasive surgery for the management of frontal traumatic intracranial hematomas. We all know that cerebral contusions are dynamic lesions and the size of the lesions and peri-lesional edema can increase over a period of time. The management of these lesions not only aims to remove radiologically visible lesions (parenchymal hematoma and/or contused brain), but also to reduce the intracranial pressure. The literature suggests that techniques that require minimal access may not be a good option in non-elderly patients if the size of the contusion is moderate or massive or follow-up imaging suggests an increase in lesion size [2]. Thus, it is important that while planning the evacuation of these lesions, we should make sure that there will also be a sufficient reduction in intracranial pressure [2]. Additionally, as an alternative to the burr hole as a minimally invasive approach, trephination has been suggested as a surgical procedure that can be used to evacuate intracerebral hematoma, particularly in elderly patients [3]. We suggest that if the surgical approach presented by Park et al. [1] could be supplemented with intracranial pressure monitoring to show that the minimally invasive approach is safe and effective for evacuating the intracerebral hematoma/ contusion and also reduces the intracranial pressure, then it will be a good adjunct in the neurosurgical armamentarium.
Obesity and Stroke: Does the Paradox Apply for Stroke?

Historically, obesity has been identified as one of the most important risk factors for developing cardiovascular diseases including stroke; however, a theory called “The Obesity Paradox” has been recently considered. The paradoxical theory is that obese or overweight patients (according to body mass index score) can have better outcomes compared to leaner or malnourished patients. The paradox was initially discovered in patients with heart failure. The purpose of this manuscript was to investigate whether this paradox also applies to stroke patients, according to information available in the current literature.
Penetrating Cardiac Injury and Traumatic Pericardial Effusion Caused by a Nail Gun
( Willem Guillermo Calderon Miranda ),( Edgardo Jimenez Fuentes ),( Nidia Escobar Hernandez ),( Luis Rafael Moscote Salazar ),( Paul M. Parizel ) 대한외상학회 2017 大韓外傷學會誌 Vol.30 No.1
Penetrating cardiac injury caused by nail gun is an uncommon life-threatening condition characterized by a rapidly severe hemodynamic status compromise. We report non-contrast-enhanced CT findings of a right ventricle myocardium injury leading to a fluid collection in the pericardial space with the same attenuation as blood. The CT findings well depicted the pathological feature of a significant cardiac injury and may be helpful for the surgical management. [ J Trauma Inj 2017; 30: 21-23 ]
Utility of medical simulation in neurovascular critical care education

Simulation has shown good results in medical scenarios in which the patient’s problem can be solved by following protocols previously established in clinical practice guidelines. Therefore, the implementation of simulation programs in neurocritical care improves the outcomes of patients at clinical centers because a properly trained professional will be able to provide the most effective care in the shortest time possible, safeguarding the patient’s life. Some learning and simulation models that can be included in medical education to improve neurocritical vascular care include task trainers, full-body mannequins, standardized patients, and computer-based simulation. Specifically, medical simulation in academic training programs in health sciences has a great impact on the development of specific skills, which could potentially reduce medical-legal and economic issues, improve care, and result in the management of clinical events. Simulation is established as an essential educational tool, allowing the instruction of knowledge from an interactive perspective and offering a broader vision when it comes to medical practice. The objective of this article is to present evidence related to the usefulness and impact of medical simulation in neurovascular critical care education.

Flow diverters have become a critical instrument for complex aneurysms treatment. However, limited data are currently available regarding short and long-term outcomes for the Silk flow diverter. The objective of the study is to determine neurological prognosis and mortality rates for the Silk flow diversion device used in intracranial aneurysms. A systematic review with meta-analysis was performed using databases. The following descriptors were used for the search: “SILK”, “Flow Diverter”, “Mortality”, and “Prognosis”. The following data were extracted: mortality, good functional outcome, Glasgow outcome scale, complete or near-complete occlusion rates, rate of retreatment, and complications (thromboembolic and hemorrhagic complications). A total of 14 studies were selected. Among the 14 studies, 13 were retrospective observational cohort studies and 1 was a prospective observational cohort study. The mortality rate was 2.84%. The clinical good outcomes rate was 93.3%. The poor outcome rate was 6.6%. The overall thromboembolic complication rate was 6.06% (95% confidence interval [CI] 0.00–6.37, P=0.12, I2=3.13%). The total hemorrhagic complication rate was 1.62% (95% CI 0.00–5.34, P=0.28, I2=1.56%). The complete aneurysm occlusion rate was 80.4% (95% CI 8.65–9.38, P<0.0001, I2=9.09%). The Silk diverter device has a good safety and efficacy profile for treating intracranial aneurysms with high complete occlusion rates.
Brain-lung interaction: a vicious cycle in traumatic brain injury

The brain-lung interaction can seriously affect patients with traumatic brain injury, triggering a vicious cycle that worsens patient prognosis. Although the mechanisms of the interaction are not fully elucidated, several hypotheses, notably the “blast injury” theory or “double hit” model, have been proposed and constitute the basis of its development and progression. The brain and lungs strongly interact via complex pathways from the brain to the lungs but also from the lungs to the brain. The main pulmonary disorders that occur after brain injuries are neurogenic pulmonary edema, acute respiratory distress syndrome, and ventilator-associated pneumonia, and the principal brain disorders after lung injuries include brain hypoxia and intracranial hypertension. All of these conditions are key considerations for management therapies after traumatic brain injury and need exceptional case-by-case monitoring to avoid neurological or pulmonary complications. This review aims to describe the history, pathophysiology, risk factors, characteristics, and complications of brain-lung and lung-brain interactions and the impact of different old and recent modalities of treatment in the context of traumatic brain injury.
