Non-compressible torso hemorrhage (NCTH) remains a significant cause of morbidity and mortality in the field of trauma and emergency medicine. In recent times, there has been a resurgence in the adoption of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) for patients who present with NCTH. Like all medical procedures, there are benefits and risks associated with the REBOA technique. However, in the case of REBOA, these complications are not unanimously agreed upon with varying viewpoints and studies. This article aims to review the current knowledge surrounding the complications of the REBOA technique at each step of its application.

In a current scenario where trauma injury and its consequences account for 9% of the worlds causes of death, the management of non-compressible torso hemorrhage can be problematic. With the improvement of medicine, the approach of these patients must be accurate and immediate so that the consequences may be minimal. Therefore, aiming the ideal method, studies have led to the development of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA). This procedure has been used at select trauma centers as a resuscitative adjunct for trauma patients with non-compressible torso hemorrhage. Although the use of this technique is increasing, its effectiveness is still not clear. This article aims, through a detailed review, to inform an updated view about this procedure, its technique, variations, benefits, limitations and future.

Since January 2017, there have been at least 1563 suspected cases of Yellow Fever, 629 confirmed cases and 232 confirmed deaths. Yellow fever is a viral hemorrhagic disease endemic to the tropical parts of Africa and South America. At the present time, it has presented a significant increase in its incidence in Brazil, with important repercussions and impacts on the public health. This review paper outlines the causes of yellow fever, as well as the disease epidemiology, progression, diagnosis, treatment and prevention. We conclude by reporting on the current epidemic in Brazil and future directions for research. Method: Data from Pubmed, SciELO, Medline and government sources concerning Yellow Fever were used, dating from 2002 to 2018. In the collection of the data the following descriptors were used: Yellow-fever, Aedes, Arbovirus and Flavivirus.
