- The pathophysiology of traumatic hemorrhage is a phenomenon of vascular disruption and the symptom of bleeding represents one or more vascular injuries. In the Circulatory Trauma paradigm traumatic hemorrhage is viewed as injury to the circulatory system and suggests the underlying basis for endovascular hemorrhage control techniques. The question "Where is the patient bleeding?" is replaced by "Which blood vessels are disrupted?" and stopping bleeding becomes a matter of selective vessel access and vascular flow control. Control of traumatic hemorrhage has traditionally been performed via external access to the end organ that is bleeding followed by the application of direct pressure, packing, or clamping and repair of directly affected blood vessels. In the circulatory trauma paradigm, bleeding is seen as disruption to vessels which may be accessed internally, from within the vascular system. A variety of endovascular treatments such as balloon occlusion, embolization, or stent grafting can be used to control hemorrhage throughout the body. This narrative review presents a brief overview of the current role of endovascular therapy in the management of circulatory trauma. The authors draw on their personal experience combined with the last decade of published experiences with the use of endovascular techniques in trauma and present general recommendations for their evolving use. The focus of the review is on the use of endovascular techniques as specific vascular treatments using the circulatory trauma paradigm.

- © 2020 The Author(s). Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) could provide a survival benefit to severely injured patients as it may improve their initial ability to survive the hemorrhagic shock. Although the evidence supporting the use of REBOA is not conclusive, its use has expanded worldwide. We aim to compare the management approaches and clinical outcomes of trauma patients treated with REBOA according to the countries' income based on the World Bank Country and Lending Groups. Methods: We used data from the AORTA (USA) and the ABOTrauma (multinational) registries. Patients were stratified into two groups: (1) high-income countries (HICs) and (2) low-to-middle income countries (LMICs). Propensity score matching extracted 1:1 matched pairs of subjects who were from an LMIC or a HIC based on age, gender, the presence of pupillary response on admission, impeding hypotension (SBP ≤ 80), trauma mechanism, ISS, the necessity of CPR on arrival, the location of REBOA insertion (emergency room or operating room) and the amount of PRBCs transfused in the first 24 h. Logistic regression (LR) was used to examine the association of LMICs and mortality. Results: A total of 817 trauma patients from 14 countries were included. Blind percutaneous approach and surgical cutdown were the preferred means of femoral cannulation in HICs and LIMCs, respectively. Patients from LMICs had a significantly higher occurrence of MODS and respiratory failure. LR showed no differences in mortality for LMICs when compared to HICs; neither in the non-matched cohort (OR = 0.63; 95% CI: 0.36-1.09; p = 0.1) nor in the matched cohort (OR = 1.45; 95% CI: 0.63-3,33; p = 0.3). Conclusion: There is considerable variation in the management practices of REBOA and the outcomes associated with this intervention between HICs and LMICs. Although we found significant differences in multiorgan and respiratory failure rates, there were no differences in the risk-adjusted odds of mortality between the groups analyzed. Trauma surgeons practicing REBOA around the world should joint efforts to standardize the practice of this endovascular technology worldwide.

- Following advances in blood typing and storage, whole blood transfusion became available for the treatment of casualties during World War I. While substantially utilized during World War II and the Korean War, whole blood transfusion declined during the Vietnam War as civilian centers transitioned to blood component therapies. Little evidence supported this shift, and recent conflicts in Iraq and Afghanistan have renewed interest in military and civilian applications of whole blood transfusion. Within the past two decades, civilian trauma centers have begun to study transfusion protocols based upon cold-stored, low anti-A/B titer type O whole blood for the treatment of severely injured civilian trauma patients. Early data suggests equivalent or improved resuscitation and hemostatic markers with whole blood transfusion when compared to balanced blood component therapy. Additional studies are taking place to define the optimal way to utilize low-titer type O whole blood in both prehospital and trauma center resuscitation of bleeding patients.

- 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-trau-matic 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.

- BACKGROUND: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may improve Systolic Blood Pressure (SBP) in hypovolemic shock. It has, however, not been studied in patients with impending traumatic cardiac arrest (ITCA). We aimed to study the feasibility and clinical outcome of REBOA in patients with ITCA using data from the ABOTrauma Registry.METHODS: Retrospective and prospective data on the use of REBOA from 16 centers globally were collected. SBP was measured both at pre- and post-REBOA inflation. Data collected included patients' demography, vascular access technique, number of attempts, catheter size, operator, zone and duration of occlusion, and clinical outcome.RESULTS: There were 74 patients in this high-risk patient group. REBOA was performed on all patients. A 7-10Fr catheter was used in 66.7%, 58.5% were placed on the first attempt, 52.1% through blind insertion and 93.2% inflated in Zone I, 64.8% for a period of 30 to 60 minutes, 82.1% by ER doctors, trauma surgeons or vascular surgeons. SBP significantly improved to 90 mmHg following the inflation of REBOA. 36.6% of the patients survived.CONCLUSIONS: Our study has shown that REBOA may be performed in patients with ITCA, SBP can be elevated and 36.6% of the patients survived if REBOA placement is successful.

- Objective: Endovascular aneurysm repair (EVAR) has been increasingly performed for ruptured abdominal aortic aneurysms (rAAAs). However, multiple randomized trials have failed to demonstrate a survival benefit compared with open aortic surgery. During a 12-year period, 100% of patients without a history of aneurysm surgery had undergone EVAR for a rAAA at orebro University Hospital, with no emergent open aortic surgery performed. In the present study, we evaluated the mortality and technical success during this "EVAR-only" period.Methods: A single-center, retrospective observational study was conducted. We identified all patients who had presented to Orebro University Hospital with a rAAA between October 2009 and September 2021. Patients with isolated iliac artery, thoracic, and thoracoabdominal aortic ruptures were not included. Patients who had received previous aortic interventions (open or endovascular) and patients who had received palliative treatment instead of surgical intervention were also excluded. The patient characteristics, perioperative and postoperative data, and mortality rate were investigated.Results: EVAR had been performed in 100 patients. Preoperative hemodynamic instability had been present in 54 patients (54%), and 18 (18%) had undergone aortic balloon occlusion. The aneurysm location was infrarenal in 89 patients (89%). Bifurcated stent grafts had been used in 97 patients (97%), and adjunct endovascular techniques had been used for 27 patients (27%). Of 98 patients, EVAR had been performed with the patient under local anesthesia for 62 patients (63%). Peri-and postoperative complications at 30 days had occurred in 20 of 100 patients (20%) and 22 of 79 patients (28%), respectively. The overall mortality at 30 days was 27% (27 of 100 patients), and the mortality for those with an isolated infrarenal rAAA was 24% (21 of 89 patients). The overall mortality at 1 year was 39% (39 of 100 patients) and for those with an isolated infrarenal rAAA was 37% (33 of 89 patients). The presence of preoperative hemodynamic instability and the use of ABO were statistically significantly and independently associated with increased 30-day mortality on multivariate logistic regression analysis.Conclusions: All 100 patients who had undergone surgery for a rAAA had been treated using EVAR and endovascular adjuncts, with a relatively low mortality rate, thus continuing the "EVAR-only" approach. A low proportion of rAAA patients were considered surgically unsuitable. These findings support the applicability of EVAR for the treatment of all rAAAs at suitable centers.

- The usage of resuscitative endovascular balloon occlusion of the aorta, also known as aortic balloon occlusion, is an emerging method for bleeding control as a bridge to definitive treatment in trauma management. We describe a trauma case where resuscitative endovascular balloon occlusion of the aorta was used as part of the EndoVascular hybrid Trauma and bleeding Management concept to facilitate transient hemorrhage control and thereby to permit damage control surgery. The case is an illustration of the adoption of a multidisciplinary approach.

- Purpose: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is now performed in many trauma centers, it is used at more than 250 hospitals in the United States and there is an increase rate of publications with the experience in these centers, but there is a gap of knowledge regarding the use of REBOA in Latin-America. This paper endeavors to describe the utilization of REBOA at a high level Latin-American Trauma Center and the transition from a large caliber to a low-profile device with the concomitant reduction in the groin access complications.Methods: A prospective, observational, single-center study was conducted. We included all trauma patients who underwent REBOA. We recorded data from admission parameters, complications, and clinical outcomes.Results: Fifty patients were included. Most of the REBOA catheters were inserted in the operating room [47 (94%)], and the arterial access was done by surgical cutdown [40 (80%)]. All the complications were associated with the catheter of 11 Fr Sheath used in 36 patients [n = 8/36 (22%) vs. n = 0/14 (0%); P = 0.05].Conclusion: REBOA can be used safely in blunt or penetrating thoracic, abdominal, and pelvic trauma. The insertion of a 7 Fr Sheath was associated with lower complications, so its use should be preferred over larger calibers.

- Successful endovascular aortic repair is highly dependent on the quality of the iliac access vessels. Patients with poor access vessels can be turned down from endovascular aortic repair or thoracic endovascular aortic repair by the treating physician. Perioperative complications such as failure to deliver the device or iliac rupture can be addressed to improper access vessels. In this article, we describe a novel technique to access the common iliac artery when access vessels are poor in diameter or quality. This sutureless conduit-free access technique can be used in TEVAR or EVAR and requires less surgical exposure of the iliac arteries.
