Endovascular Instead of Open Surgical Repair of Axillosubclavian Artery Injuries: An Evolving Paradigm Shift

Axillosubclavian injuries (ASI) comprise a small proportion of vascular injuries, yet their morbidity and mortality is high. This is often attributable to non-compressible bleeding in the apical thorax, hemodynamic instability, and the anatomically challenging location of these vessels making them difficult to access and control quickly. While the traditional management of ASI was with open surgical repair (OSR), recent years have seen an evolution towards less invasive endovascular repair (EVR). In patients with these injuries, EVR may be a safer alternative that achieves similar immediate results with significantly lower complication and mortality rates than the highly morbid open surgical option. In this article, we review and compare the two approaches, providing an overview of patient selection, anatomic considerations, techniques, postoperative management, and outcomes. With the advent of EVTM and more trauma team members capable of endovascular management of vascular trauma, a paradigm shift towards EVR for ASI is taking place.

Current Standards for and Clinical Impact of Emergency Radiology in Major Trauma

In industrialized countries, high energy trauma represents the leading cause of death and disability among people under 35 years of age. The two leading causes of mortality are neurological injuries and bleeding. Clinical evaluation is often unreliable in determining if, when and where injuries should be treated. Traditionally, surgery was the mainstay for assessment of injuries but advances in imaging techniques, particularly in computed tomography (CT), have contributed in progressively changing the classic clinical paradigm for major traumas, better defining the indications for surgery. Actually, the vast majority of traumas are now treated nonoperatively with a significant reduction in morbidity and mortality compared to the past. In this sense, another crucial point is the advent of interventional radiology (IR) in the treatment of vascular injuries after blunt trauma. IR enables the most effective nonoperative treatment of all vascular injuries. Indications for IR depend on the CT evidence of vascular injuries and, therefore, a robust CT protocol and the radiologist’s expertise are crucial. Emergency and IR radiologists form an integral part of the trauma team and are crucial for tailored management of traumatic injuries.

Prehospital Tourniquet Use Should be a Trauma Team Activation Criterion.

Purpose Prehospital tourniquet application is not a standard trauma team activation (TTA) criterion recommended by the ACS COT. Tourniquet use has seen a resurgence recently with associated risks and benefits of more liberal usage. Our institution added tourniquet application as TTA criterion in January 2019. This study aimed to evaluate the effect this would have on patient care and overtriage. Methods A prospective analysis was conducted for all TTA associated with tourniquets placed during 2019. An overtriage analysis was conducted utilizing a modified Cribari method as described in Resources for the Optimal Care of the Injured Patient, comparing patients that met standard TTA criteria (TTA-S), to those who met criteria due to tourniquet placement (TTA-T). Results During the study, there were 46 TTA with tourniquets. Mean prehospital tourniquet time was 80 minutes. Median ISS was 10, 8 (17%) had an ISS >15. Urgent operative intervention was needed in 74%, with 23% and 21% requiring orthopedic and vascular procedures, respectively. Tourniquets were correctly placed in 80% and clinically appropriate in 57%. Of these subjects, 25 (54%) were TTA-S and 21 TTA-T. Overtriage analysis was performed. Overtriage for TTA-T was 33.3%. Overtriage among TTA-S was 4%. Conclusion Patients with prehospital tourniquets are frequently severely injured. The immediate presence of a trauma surgeon can have significant impacts in these cases. This is particularly important in a rural environment with long tourniquet times. Prehospital tourniquet application as a TTA criteria does not result in excessive overtriage.

Perioperative Management of Polytrauma Patients with Severe Traumatic Brain Injury Undergoing Emergency Extracranial Surgery: A Narrative Review

Managing the acute phase after a severe traumatic brain injury (TBI) with polytrauma represents a challenging situation for every trauma team member. A worldwide variability in the management of these complex patients has been reported in recent studies. Moreover, limited evidence regarding this topic is available, mainly due to the lack of well-designed studies. Anesthesiologists, as trauma team members, should be familiar with all the issues related to the management of these patients. In this narrative review, we summarize the available evidence in this setting, focusing on perioperative brain protection, cardiorespiratory optimization, and preservation of the coagulative function. An overview on simultaneous multisystem surgery (SMS) is also presented.

Trauma Computed Tomography in the Modern Era: Not Always Quick and Safe

Background Computed tomography (CT) has emerged as the diagnostic modality of choice in trauma patients. Recent studies suggest its use in hemodynamically unstable patients is safe and potentially lifesaving; however, the incidence of adverse events (AE) during the trauma CT scanning process remains unknown. Study Design Over a 6-month period at a Level 1 trauma center, data on patients undergoing trauma CT (whole-body CT (WBCT) +/− additional CT studies) were prospectively collected. All patients requiring a trauma team activation (TTA) were included. Adverse events and specific time intervals were recorded from the time of TTA notification to the time of return to the resuscitation bay from the CT suite. Results Of the 94 consecutive patients included in the study, 47.9% experienced 1 or more AE. Median duration away from the resuscitation bay for all patients was 24 minutes. Patients with AE spent a significantly longer time away from the resuscitation bay and had longer scan times. Vasopressor support and ongoing transfusion requirement at the time of CT scanning were associated with AE. Conclusion Adverse events of varying clinical significance occur frequently in patients undergoing emergent trauma CT. A standard trauma CT protocol could improve the efficiency and safety of the scanning process.
