O Tribunal Penal Internacional
Authors: Velloso Ricardo Ribeiro
Published: September 2017

A criação de tribunais para julgar ações que afetam a humanidade como um todo, já vem se tornando uma constante desde a Segunda Guerra Mundial e do Tribunal de Nuremberg, mesmo que esses atos sejam praticados por nacionais, dentro do território de seus países.Dentro desse espírito foi criado em Julho de 1998, pelo Tratado de Roma, o Tribunal Penal Internacional, que tem como função o julgamento de crimes contra a humanidade, quais sejam, genocídio, crimes de guerra, dentre outros.A idéia de um Tribunal Penal Internacional já foi acatada por 138 Estados, sendo necessário para sua entrada em vigor que, no mínimo, 60 países ratificassem seu Estatuto, o que já aconteceu. A Corte Internacional terá sede em Holanda, e será composta por 18 países. Com o início dos trabalhos do TP1 não será mais necessário a criação de Tribunais ad hoc, terminando com as discussões em torno da legitimidade desses tribunais.

We present the successful utilization of resuscitative endovascular balloon occlusion of the aorta (REBOA) in a case of penetrating abdominal aortic injury. This allowed for hemorrhagic control and exposure of a large aortic defect at the level of the celiac access, which otherwise would have been diffi cult to control in an open fashion. Although use in this specifi c injury pattern in the literature is limited, REBOA can be a life-saving maneuver.

Published: September 2017

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is currently evolving and being used worldwide for trauma management. Smaller sheath devices for REBOA and new advances in endovascular resuscitation methods suggest the potential for the procedure to be utilized in hemodynamically unstable non-traumatic patients.Methods: We describe five adult patients that underwent hemodynamic control using the 7 Fr sheath ER-REBOA™ catheters for non-traumatic hemorrhagic instability at Örebro University Hospital between February 2017 and June 2017. Results: The ER-REBOA™ catheter was inserted and used successfully for temporary blood pressure stabilization as part of an endovascular resuscitation process.Conclusion: The ER-REBOA™ catheter for endovascular resuscitation may be an additional method for temporary hemodynamic stabilization in the treatment of non-traumatic patients. Furthermore, the ER-REBOA™ catheter may be a potential addition to advanced cardiac life support in the management of non-traumatic cardiac arrest.
Trauma Pan-Scan in Resuscitative Endovascular Occlusion: A Novel Strategy for Hemodynamically Unstable Polytrauma Patients
Authors: Matsumura Yosuke , Matsumoto Junichi
Published: September 2017

The trauma pan-scan (TPS) offers particular benefits in trauma care. Resuscitative endovascular balloon occlusion of the aorta (REBOA) may provide an opportunity to scan hemodynamically unstable (HU) polytrauma patients; however, the benefits and risks of REBOA-TPS remain unknown. The rationale for TPS in HU patients is to choose the best intervention and to quickly achieve hemostasis rather than directly initiating surgery without scanning. TPS would most greatly benefit geriatric trauma patients and those with coagulopathies with unidentified bleeding sources, particularly noncavitary hemorrhage in blunt trauma and accompanying brain injury, because TPS may predict unexpected physiological collapse via anatomical imaging. Computed tomography (CT) is a common cause of flow disruption, but specific trauma team training was shown to reduce the time spent in the CT room from 16.8 to 7.3 minutes (P < 0.001). While REBOA-TPS cannot be utilized widely or indiscriminately, its appropriate use may increase the number of salvageable trauma patients.

Hemorrhage is the second leading cause of death in trauma and non-compressible torso hemorrhage is the leading cause of preventable death within this population. Vascular injuries to the pelvis and lower extremity junctional zone may be difficult to control with direct pressure and complex to approach with open surgery. Endovascular interventions such as balloon occlusion, stenting, and embolization are potential alternatives or adjuncts to traditional open surgery in patients with blunt or penetrating vascular injuries to the pelvis. This review of the literature will outline contemporary endovascular management strategies for iliac and junctional zone injuries.
