The use of aortic balloon occlusion in traumatic shock : first report from the ABO trauma registry
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique for temporary stabilization of patients with non-compressible torso hemorrhage. This technique has been increasingly used worldwide during the past decade. Despite the good outcomes of translational studies, clinical studies are divided. The aim of this multicenter-international study was to capture REBOA-specific data and outcomes. REBOA practicing centers were invited to join this online register, which was established in September 2014. REBOA cases were reported, both retrospective and prospective. Demographics, injury patterns, hemodynamic variables, REBOA-specific data, complications and 30-days mortality were reported. Ninety-six cases from 6 different countries were reported between 2011 and 2016. Mean age was 52 +/- 22 years and 88% of the cases were blunt trauma with a median injury severity score (ISS) of 41 (IQR 29-50). In the majority of the cases, Zone I REBOA was used. Median systolic blood pressure before balloon inflation was 60 mmHg (IQR 40-80), which increased to 100 mmHg (IQR 80-128) after inflation. Continuous occlusion was applied in 52% of the patients, and 48% received non-continuous occlusion. Occlusion time longer than 60 min was reported as 38 and 14% in the non-continuous and continuous groups, respectively. Complications, such as extremity compartment syndrome (n = 3), were only noted in the continuous occlusion group. The 30-day mortality for non-continuous REBOA was 48%, and 64% for continuous occlusion. This observational multicenter study presents results regarding continuous and non-continuous REBOA with favorable outcomes. However, further prospective studies are needed to be able to draw conclusions on morbidity and mortality.Peer reviewe
Pre-hospital CPR and early REBOA in trauma patients-results from the ABOTrauma Registry
Publisher Copyright: © 2020 The Author(s).Background: Severely injured trauma patients suffering from traumatic cardiac arrest (TCA) and requiring cardiopulmonary resuscitation (CPR) rarely survive. The role of resuscitative endovascular balloon occlusion of the aorta (REBOA) performed early after hospital admission in patients with TCA is not well-defined. As the use of REBOA increases, there is great interest in knowing if there is a survival benefit related to the early use of REBOA after TCA. Using data from the ABOTrauma Registry, we aimed to study the role of REBOA used early after hospital admission in trauma patients who required pre-hospital CPR. Methods: Retrospective and prospective data on the use of REBOA were collected from the ABOTrauma Registry from 11 centers in seven countries globally between 2014 and 2019. In all patients with pre-hospital TCA, the predicted probability of survival, calculated with the Revised Injury Severity Classification II (RISC II), was compared with the observed survival rate. Results: Of 213 patients in the ABOTrauma Registry, 26 patients (12.2%) who had received pre-hospital CPR were identified. The median (range) Injury Severity Score (ISS) was 45.5 (25-75). Fourteen patients (54%) had been admitted to the hospital with ongoing CPR. Nine patients (35%) died within the first 24 h, while seventeen patients (65%) survived post 24 h. The survival rate to hospital discharge was 27% (n = 7). The predicted mortality using the RISC II was 0.977 (25 out of 26). The observed mortality (19 out of 26) was significantly lower than the predicted mortality (p = 0.049). Patients not responding to REBOA were more likely to die. Only one (10%) out of 10 non-responders survived. The survival rate in the 16 patients responding to REBOA was 37.5% (n = 6). REBOA with a median (range) duration of 45 (8-70) minutes significantly increases blood pressure from the median (range) 56.5 (0-147) to 90 (0-200) mmHg. Conclusions: Mortality in patients suffering from TCA and receiving REBOA early after hospital admission is significantly lower than predicted by the RISC II. REBOA may improve survival after TCA. The use of REBOA in these patients should be further investigated.Peer reviewe
Pelvic trauma : WSES classification and guidelines
Complex pelvic injuries are among the most dangerous and deadly trauma related lesions. Different classification systems exist, some are based on the mechanism of injury, some on anatomic patterns and some are focusing on the resulting instability requiring operative fixation. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic impairment of pelvic ring function and the associated injuries. The management of pelvic trauma patients aims definitively to restore the homeostasis and the normal physiopathology associated to the mechanical stability of the pelvic ring. Thus the management of pelvic trauma must be multidisciplinary and should be ultimately based on the physiology of the patient and the anatomy of the injury. This paper presents the World Society of Emergency Surgery (WSES) classification of pelvic trauma and the management Guidelines.Peer reviewe
Complete endovascular renal and visceral artery revascularization and exclusion of a ruptured type IV thoracoabdominal aortic aneurysm
PURPOSE: To present a technique for renal and visceral revascularization allowing complete endovascular treatment of a ruptured type IV thoracoabdominal aneurysm using devices already stocked in most centers performing endovascular aneurysm repair. TECHNIQUE: Open arterial access is obtained to both common femoral arteries and the left subclavian artery (LSA). Access to the visceral and renal arteries is obtained through separate 8-F sheaths for each visceral and renal branch. Both visceral arteries (celiac trunk and superior mesenteric artery) are accessed through 2 separate sheaths placed into the LSA, and both renal arteries are accessed through 2 separate sheaths placed into the left common femoral artery. Corresponding covered stents are introduced and positioned in the celiac trunk, superior mesenteric artery, and both renal arteries but not deployed. The aortic stent-graft is then introduced and deployed through the right common femoral artery. Once the aneurysm exclusion is completed, the stent-grafts to the branches are deployed so that they are positioned between the aortic wall and the aortic stent-graft. Finally, the branch stent-grafts as well as the aortic stent-graft are fully expanded with balloon catheters inflated simultaneously as in the kissing balloon technique. CONCLUSION: To our knowledge, no one has reported using this technique to successfully treat a ruptured thoracoabdominal aneurysm and revascularize all 4 major renovisceral arteries. A main advantage of this technique over use of branched stent-grafts is that it can be performed even in the emergency setting with devices that are in stock in most institutions performing endovascular aneurysm exclusion

Thoracic Endovascular Aortic Repair of Aortic Arch Pathologies with the Conformable Thoracic Aortic Graft: Early and 2 year Results from a European Multicentre Registry
Objective: To assess safety, effectiveness and clinical outcome of the conformable thoracic aortic endograft (CTAG) in the treatment of aortic arch pathologies. Methods: Between October 2009 and December 2010, 100 consecutive patients (65 men; mean age 65 years) with aortic arch pathologies were treated with the CTAG device in five European centres. Indications were thoracic aortic aneurysm (n = 57), Type B dissection (n = 24), intramural haematoma (n = 4), penetrating aortic ulcer (n = 9), and traumatic transection (n = 6). Emergency procedures were performed in 33%.The proximal landing zone (LZ) was LZ 0 in 7%, LZ 1 in14%, LZ 2 in 43%, and LZ 3 in 36%. Data were collected prospectively and analysed for technical and clinical success. Conformability and deployment accuracy were analysed on intra-operative angiography and postoperative computed tomography. Mean follow up was 24 +/- 19 months (range, 0.3-36 months). Results: The 30 day, 1 and 2 year survival rates were 90%, 81%, and 74% respectively. The 2 year survival was 80% in the elective and 62% in the emergency groups (p = .20). The major 30 day complication rate was 34%: primary Type la endoleak affected 1%, retrograde dissection in 1%, and the paraplegia and stroke rates at 30 days were 4% and 11%. Age > 70 years was an independent predictor for mortality and complications. The primary technical success rate was 92%; device deployment was successful in 100% and accurate in 99%. Conformability to the aortic arch was achieved in 95%. Conclusion: The CTAG stent graft shows high deployment accuracy, good conformability, and clinical effectiveness in the treatment of aortic arch pathologies. However, thoracic endovascular aortic repair in the arch is associated with a relatively high stroke rate. Further studies with more patients and longer follow up are needed to evaluate the long-term results. (C) 2016 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved
Complete replacement of open repair for ruptured abdominal aortic aneurysms by endovascular aneurysm repair: a two-center 14-year experience
OBJECTIVE: : To present the combined 14-year experience of 2 university centers performing endovascular aneurysm repair (EVAR) on 100% of noninfected ruptured abdominal aortic aneurysms (RAAA) over the last 32 months.
BACKGROUND: : Endovascular aneurysm repair for RAAA feasibility is reported to be 20% to 50%, and EVAR for RAAA has been reported to have better outcomes than open repair.
METHODS: : We retrospectively analyzed prospectively gathered data on 473 consecutive RAAA patients (Zurich, 295; Ă–rebro, 178) from January 1, 1998, to December 31, 2011, treated by an "EVAR-whenever-possible" approach until April 2009 (EVAR/OPEN period) and thereafter according to a "100% EVAR" approach (EVAR-ONLY period).Straightforward cases were treated by standard EVAR. More complex RAAA were managed during EVAR-ONLY with adjunctive procedures in 17 of 70 patients (24%): chimney, 3; open iliac debranching, 1; coiling, 8; onyx, 3; and chimney plus onyx, 2.
RESULTS: : Since May 2009, all RAAA but one have been treated by EVAR (Zurich, 31; Ă–rebro, 39); 30-day mortality for EVAR-ONLY was 24% (17 of 70). Total cohort mortality (including medically treated patients) for EVAR/OPEN was 32.8% (131 of 400) compared with 27.4% (20 of 73) for EVAR-ONLY (P = 0.376). During EVAR/OPEN, 10% (39 of 400) of patients were treated medically compared with 4% (3 of 73) of patients during EVAR-ONLY. In EVAR/OPEN, open repair showed a statistically significant association with 30-day mortality (adjusted odds ratio [OR] = 3.3; 95% confidence interval [CI], 1.4-7.5; P = 0.004). For patients with no abdominal decompression, there was a higher mortality with open repair than EVAR (adjusted OR = 5.6; 95% CI, 1.9-16.7). In patients with abdominal decompression by laparotomy, there was no difference in mortality (adjusted OR = 1.1; 95% CI, 0.3-3.7).
CONCLUSIONS: : The "EVAR-ONLY" approach has allowed EVAR treatment of nearly all incoming RAAA with low mortality and turndown rates. Although the observed association of a higher EVAR mortality with abdominal decompression needs further study, our results support superiority and more widespread adoption of EVAR for the treatment of RAAA
