Blunt Traumatic Aortic Injury Management, a French TraumaBase Analytic Cohort. Eur J Vasc Endovasc Surg 2022; 63:401-409. [PMID: 35144894 DOI: 10.1016/j.ejvs.2021.09.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Revised: 09/13/2021] [Accepted: 09/28/2021] [Indexed: 11/03/2022]
Abstract
OBJECTIVE Blunt traumatic aortic injury (BTAI) in severe trauma patients is rare but potentially lethal. The aim of this work was to perform a current epidemiological analysis of the clinical and surgical management of these patients in a European country. METHODS This was a multicentre, retrospective study using prospectively collected data from the French National Trauma Registry and the National Uniform Hospital Discharge Database from 10 trauma centres in France. The primary endpoint was the prevalence of BTAI. The secondary endpoints focused chronologically on injury characteristics, management, and patient outcomes. RESULTS 209 patients were included with a mean age of 43 ± 19 years and 168 (80%) were men. The calculated prevalence of BTAI at hospital admission was 1% (162/15 094) (BTAI admissions/all trauma). The time to diagnosis increased with the severity of aortic injury and the clinical severity of the patients (grade 1: 94 [74, 143] minutes to grade 4: 154 [112, 202] minutes, p = .020). This delay seemed to be associated with the intensity of the required resuscitation. Sixty seven patients (32%) received no surgical treatment. Among those treated, 130 (92%) received endovascular treatment, 14 (10%) open surgery (two were combined), and 123 (85%) were treated within the first 24 hours. Overall mortality was 20% and the attributed cause of death was haemorrhagic shock (69%). Mortality was increased according to aortic injury severity, from 6% for grade 1 to 65% for grade 4 (p < .001). Twenty-six (18.3%) patients treated by endovascular aortic repair had complications. CONCLUSION BTAI prevalence at hospital admission was low but occurred in severe high velocity trauma patients and in those with a high clinical suspicion of severe haemorrhage. The association of shock with high grade aortic injury and increasing time to diagnosis suggests a need to optimise early resuscitation to minimise the time to treatment. Endovascular treatment has been established as the reference treatment, accounting for more than 90% of interventional treatment options for BTAI.

Abstract
Aortic injury, particularly traumatic aortic dissection caused by thoracic and abdominal injuries, is extremely rare. The diagnosis rate of blunt aortic injury caused by chest and abdominal injuries is often low, and its clinical manifestations are atypical. Once missed or misdiagnosed, the consequences are serious. Early diagnosis of traumatic aortic injury in complex thoracic and abdominal injuries is a key factor in reducing the mortality of trauma patients. Among all trauma patients treated in our department from December 2018 to December 2020, we diagnosed four cases of aortic injury, including three cases of aortic dissection and one case of intramural hematoma. Successful surgical treatment and clinical outcome were achieved in all four patients. We found that early diagnosis and surgical treatment can help to reduce the mortality of patients with traumatic aortic injury and improve the prognosis.

Abstract
Thoracic aortic injuries caused by high impact trauma are life-threatening and require emergent diagnosis and management. With improvement in the acute care services, an increasing number of such injuries are being managed such that patients survive to undergo definitive therapies. A high index of clinical suspicion is required to order appropriate imaging. Computed tomography angiography is used to classify the injuries and guide treatment strategy. While low-grade injuries might be managed conservatively, high-grade injuries require urgent surgical or endovascular intervention. Over the past decade, endovascular repair of the thoracic aorta with or without a surgical bypass has become the preferred treatment with reduced mortality and morbidity. Rapid advancements in the stent graft technology have reduced the anatomic barriers to endovascular therapy and increased the confidence of the operators. Detailed planning prior to the procedure, understanding of the anatomy, correct choice of hardware, and adherence to technical protocol are essential for a successful endovascular procedure. These patients are often young and the limited data on the long-term outcome of aortic stent grafts make a case for a robust follow-up protocol.

Abstract
INTRODUCTION The optimal management of minimal blunt thoracic aortic injuries (BTAIs) remains controversial, with experienced centers using therapy ranging from medical management (MM) to thoracic endovascular aortic repair (TEVAR). METHODS The Aortic Trauma Foundation registry was used to examine demographics, injury characteristics, management, and outcomes of patients with BTAI. RESULTS Two hundred ninety-six patients from 28 international centers were analyzed (mean age, 44.5 years [SD, 18 years]; 76% [225/296] male; mean Injury Severity Score, 34 [SD, 14]). Blunt thoracic aortic injury was classified as Grade I, 22.6% (67/296); Grade II, 17.6% (52/296); Grade III, 47.3% (140/296); and Grade IV, 12.5% (37/296). Overall aortic-related mortality (ARM) was 4.7% (14/296). Among all deaths, 33% (14/42) were ARM. Open repair was required for only 2%, with most undergoing TEVAR (58.4%) or MM (28.0%). Thoracic endovascular repair complications occurred in 3.4% (6/173), most commonly Type 1 endoleak (2.3%; 4/173). Among patients with minimal aortic injury (Grades I and II), 59.7% (71/119) received MM, while 40.3% (48/119) underwent TEVAR. Two patients initially managed with MM required subsequent TEVAR for injury progression during initial hospital stay. No significant difference in ARM between MM and TEVAR was noted for Grades I and II injuries. CONCLUSION A third of the trauma victims with BTAI succumb to ARM. Thoracic endovascular repair has replaced open repair but remains equivalent in outcomes to MM for minimal injuries. These data support MM of patients with minimal aortic injury. LEVEL OF EVIDENCE Therapeutic study, level IV.

Abstract
BACKGROUND Blunt thoracic aortic injury (BTAI) is associated with a high mortality and large trauma burden. Trauma and resuscitation after injury affect cardiovascular status, which may in turn affect aortic diameter. Measurement of aortic diameter is necessary to guide stent-graft sizing as part of BTAI management. Inaccurate measurement may lead to stent-graft complications. This pilot study aimed to assess the effect of acute major trauma on stent-graft sizing and stent-graft complications, in the context of BTAI and to assess whether any effect could be predicted. METHODS Patients who were admitted to a UK major trauma center between January 2007 and December 2017, and were diagnosed with BTAI, were identified. The thoracic aortic diameter was measured at six points on initial and surveillance computed tomography imaging. Data on patient demographics, admission heart rate, mean arterial pressure (MAP), and serum lactate were gathered. RESULTS Thirty-two patients were identified. Twenty met inclusion criteria. Of these, 12 were managed operatively and eight nonoperatively. The mean age was 40, the mean injury severity score was 43, and 85% were male. A mean increase in diameter between initial trauma scan and surveillance scan was noted throughout the thoracic aorta (P < 0.05). Stent-graft oversizing relative to aortic diameter changed significantly from initial trauma imaging to surveillance imaging (P < 0.05). Admission heart rate, MAP, and serum lactate were not predictive of the percentage change in aortic diameter. There were no complications at surveillance imaging (mean 45 days) or during medium term follow-up (mean 532 days). CONCLUSIONS Aortic diameter is affected by BTAI, acute major trauma, and resuscitation in a significant and variable manner. Measurements of the aorta in a patient with BTAI in the acute trauma setting should be viewed with uncertainty. A lack of complications in the short term is suggestive of a wide tolerance range regarding stent-graft sizing, but long-term results are unknown.

Abstract
The clinical spectrum of pericardial effusions varies from innocuous serous fluid to life-threatening hemopericardium. A misdiagnosis may be made by similar clinical presentation of acute chest pain/hypotension. Echocardiography is the first-line test for diagnosis of pericardial effusion and its etiology, but sometimes there are different drawbacks to the correct cardiovascular ultrasound diagnosis. Radiologists are reporting an increasing amount of thoracic Multidetector CT examinations at the emergency department. Multidetector CT has now become an established and complementary method for cardiac imaging, and diseases of the pericardium can now be quickly identified with increasing certainty. The aim of this review is to discuss the hemopericardium key Multidetector CT features in acute clinical setting which indicate the need to proceed with predominantly medical or surgical treatment, however, being able to identify forms of bleeding pericardial effusion for which only "a watch and wait strategy" and/or deferred treatment is indicated. In the emergency care setting, radiologists must be aware of different findings of hemopericardium in order to address a tailored and timely management approach.

Abstract
OBJECTIVES The most widely accepted grading system for blunt traumatic aortic injury (BTAI) by the Society of Vascular Surgery (SVS) recommends endovascular repair for grade 2 and greater. Non-operative management in grade 2 injuries has been shown to be reasonable in certain circumstances. The natural history of low-grade injuries (1, 2) when managed non-operatively is not well defined. METHODS Utilizing our trauma registry, patients from 2013 to 2016 with blunt traumatic injury who underwent initial computed tomography were identified. Aortic pathology was graded and grouped by SVS classification. Clinical courses were reviewed for timing of interventions, repeat imaging, concurrent injuries, and outcomes. Analysis of variance and Chi-square tests of significance were utilized to compare between groups. RESULTS Out of 10,178 patients, we identified 32 with BTAI (grade: 1 (n = 13), 2 (n = 5), 3 (n = 3), 4 (n = 11)). High-grade injuries (3, 4) resulted only from motor vehicle, motorcycle, and pedestrian mechanisms. Initially, 9 patients (28%) required intervention, 5 (16%) were treated non-operatively, and 18 (56%) underwent repeat imaging. On repeat imaging, injuries that did not resolve remained stable and no injuries were found to progress. Of these patients, 9 (50%) required delayed intervention and 9 (50%) successfully underwent non-operative management. Patients with low-grade injuries were more likely to have successful non-operative management than those with high-grade injuries (72% vs 7%; p < 0.01). CONCLUSIONS While low-grade injuries generally have good outcomes, some ultimately do require delayed intervention, and short-term imaging is not reliable in identifying these cases.

Abstract
Over the last 2 decades, increased depiction of minimal aortic injury (MAI) in the evaluation of patients who have sustained trauma has mirrored the increased utilization and improved resolution of multidetector CT. MAI represents a mild form of blunt traumatic aortic injury (BTAI) that usually resolves or stabilizes with pharmacologic management. The traditional imaging manifestation of MAI is a subcentimeter round, triangular, or linear aortic filling defect attached to an aortic wall, representing a small intimal flap or thrombus consistent with grade I injury according to the Society for Vascular Surgery (SVS). Small intramural hematoma (SVS grade II injury) without external aortic contour deformity is included in the MAI spectrum in several BTAI classifications on the basis of its favorable outcome. Although higher SVS grades of injury generally call for endovascular repair, there is growing literature supporting conservative management for small pseudoaneurysms (SVS grade III) and large intimal flaps (>1 cm, unclassified by the SVS), hinting toward possible future inclusion of these entities in the MAI spectrum. Injury progression of MAI is rare, with endovascular aortic repair reserved for these patients as well as patients for whom medical treatment cannot be implemented. No consensus on the predetermined frequency and duration of multidetector CT follow-up exists, but it is common practice to perform a repeat CT examination shortly after the initial diagnosis. The authors review the evolving definition, pathophysiology, and natural history of MAI, present the primary and secondary imaging findings and diagnostic pitfalls, and discuss the current management options for MAI.

Abstract
INTRODUCTION Thoracic endovascular aortic repair (TEVAR) for treatment of blunt traumatic aortic injuries (BTAIs) is nowadays the gold standard technique in adult patients, replacing gradually the use of open repair (OR). Although randomized controlled trials will never be performed comparing TEVAR to OR for BTAIs management, trauma and vascular societies guidelines today primarily recommend the former for BTAI patients with a suitable anatomy. The aim of this review was to describe past and recent data published in literature regarding pros and cons of TEVAR treatment in BTAI, and to analyze some debated issues and future perspectives. EVIDENCE ACQUISITION Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Scale for the Assessment of Narrative Review Articles (SANRA) were used to obtain and describe selected articles on TEVAR in BTAI. EVIDENCE SYNTHESIS Young (<50 years) men were the most operated population. The use of TEVAR increased over the years, with a progressive reduction in mortality and overall postoperative complication rates when compared with OR. Lack of information remains about the percentage of urgent cases. CONCLUSIONS TEVAR is considered nowadays the treatment of choice in BTAI patients. In case of aortic rupture (grade IV) the treatment is mandatory, while intimal tear (grade I) and intramural hematoma (grade II) can be safely managed with no operative management (NOM). Debate is still ongoing on grade III (pseudoaneurysms). Unfortunately, several aspects remain not yet clarified, including disease classification, type and grade to treat, timing (urgent versus elective), priority of vascular injuries in polytrauma patients, and TEVAR use in pediatrics and young patients.

Abstract
Background Non-operative management is considered appropriate treatment for minor aortic injury, while blood pressure and anti-impulse therapy are routinely utilized to prevent higher grade aortic injury progression. However, a universal medical regimen for low grade intimal injuries has not been adopted and risks of low-grade injury progression not well described. The purpose of this study is to determine the fracture response of minimally damaged aortic tissue to the various applied forces. Our hypothesis is that internal circumferential shear within the aortic wall is a primary fracture mode. This knowledge may help guide clinical management to minimize risk of injury progression, including instituting standard medical regimens with anti-impulse therapy and β-blockade for such minor injuries. Methods Human ascending aortic tissue was obtained after aneurysm repair or heart transplant, stored at 4°C and tested within 48 hours. Minor injury was modeled with a small radial notch on the luminal aspect of aortic rings, circumferentially expanded under video acquisition and analyzed to determine lesion propagation. Results 15 rings were obtained from 8 aneurysmal and 4 healthy aortas. All specimens demonstrated circumferential crack propagation. Propagation was longer (8.02 ± 5.92 mm vs 2.70 ± 1.23 mm) and initiation of crack propagation earlier in aneurysmal tissue (1.54 ± 0.17 versus 1.90 ± 0.17 times initial diameter). Conclusions Dilation of minimally injured aortic rings is associated with lesion expansion and injury progression in all specimens including healthy and aneurysmal tissue. This propagation illustrates the mechanical response to increased levels of internal shear, compromising structural integrity and increasing risk of aortic rupture in all injured aortas. Shear forces are routinely generated through normal circumferential aortic expansion with each pulsation, the magnitude of these forces determined by pulse and blood pressure. This suggests minor aortic injuries are not trivial and strategies to reduce shear stress be implemented in all such patients without contraindications to β- blockers.

Abstract
BACKGROUND Thoracic endovascular aortic repair has transformed the management of blunt traumatic thoracic aortic injuries (BTTAI). Recent studies have suggested that the nonoperative management (NOM) of BTTAI may be a viable alternative. We investigated the NOM of BTTAI by conducting a systematic review and meta-analysis of the mortality proportions and incidence of complications. METHODS We searched PubMed through June 22, 2017, and referenced lists of included studies without language restriction, with the assistance of a trained librarian. We included studies that reported the NOM of BTTAI (≥5 participants). Two authors independently screened titles, abstracts, and performed data extraction. Pooled prevalence of mortality (aortic related, in hospital) were obtained based on binomial distribution with Freeman-Tukey double-arcsine transformation and continuity correction. The random-effects model was used for all analyses to account for variation between studies. Meta-regression was performed to explore sources of heterogeneity, including Injury Severity Score, age, and gender. RESULTS We included 35 studies comprising 2897 participants. The pooled prevalence of all-cause in-patient mortality in the overall, grade I, grade II, grade III, and grade IV populations are as follows: 29.0% (95% confidence interval [CI], 19.3%-39.6%; I2 = 95%; P < .01), 6.8% (95% CI, 0.6%-19.3%; I2 = 52%; P = .03), 0% (95% CI, 0%-2.0%; I2 = 0%; P = .81), 29.2% (95% CI, 17%-42.5%; I2 = 3%; P = .41), and 87.4% (95% CI, 16.4%-100%; I2 = 48%; P = .14), respectively. The combined incidence of aortic-related in-patient mortality in the overall, grade I, grade II, and grade III populations are: 2.4% (95% CI, 0.4%-5.5%; I2 = 60%; P < .01), 0.93% (95% CI, 0%-14.2%; I2 = 65%; P < .01), 0% (95% CI, 0%-1.8%; I2 = 0%; P = .99), and 0.13% (95% CI, 0%-6.4%; I2 = 14%; P = .33), respectively. The total proportion of postdischarge aortic-related mortality is 0% (95% CI, 0%-0.5%; I2 = 0%; P = .91). Meta-regression showed a decreased risk of in-hospital mortality as age increases (β = .99; 95% CI, 0.98-1.00), an increased risk of in-hospital mortality with a higher Injury Severity Score (β = 1.02; 95% CI, 1.00-1.04), and a decreased risk of in-hospital mortality among male patients (β = .54; 95% CI, 0.3-0.90). CONCLUSIONS This study provides, to our knowledge, the most up-to-date pooled estimate of mortality rates after the NOM of BTTAI. However, its interpretation is limited by the paucity of data and substantial quantitative heterogeneity. If patients are to be managed nonoperatively, we would recommend the judicious use of active surveillance in a select group of patients in the short, mid, and long term.

Abstract
PURPOSE Blunt aortic injuries (BAI) have historically been considered an indication for emergent surgical intervention. Nevertheless, the observation that the outcome of the concomitant traumatic injuries has a major impact on prognosis and the rise of thoracic endovascular aortic repair (TEVAR) as an effective therapy for BAI have significantly changed in recent years the treatment algorithm of this condition. Our objective was to identify findings associated with the aortic injury which would be the best predictor of prognosis, with the objective of guiding the decision-making process for selecting the optimal timing of aortic repair. METHODS We reviewed blunt aortic injuries from 3 Level I Trauma Centers from July 2008 to December 2016. We analyzed overall and BAI-related 30-day mortality in relation to: hemodynamics, timing of treatment, TEVAR vs open repair, and aortic injury grade as defined by the Society for Vascular Surgery. Based on computed tomographic angiography (CT scan) imaging, we selected the radiologic aortic findings most indicative of high mortality risk, which we defined as "Radiographic Severe Injury" (RSI): (1) total/partial aortic transection, (2) active contrast extravasation, or (3) the association of 2 of more of the following: contained contrast extravasation > 10 mm, periaortic hematoma, and/or mediastinal hematoma with thickness > 10 mm, or significant left pleural effusion. RESULTS Of a total of 76 consecutive patients, 50 (66%) underwent immediate repair, 24 (31%) delayed aortic repair, and 2 (3%) died prior to repair. 58 patients (76%) had TEVAR, while 16 (24%) had open repair. Overall mortality was 18% and BAI-related mortality was 13%. In BAI-related mortalities, 70% of patients had RSI. Patients with high risk of overall mortality had hypotension and tachycardia (SBP < 100, HR ≥ 100), high ISS, and required vasopressors. Factors only associated with BAI-related mortality included RSI. CONCLUSION CT scan findings suggestive of RSI are predictive of mortality associated with BAI. Radiologic assessment of the severity of the aortic injury with characterization for the presence of RSI may represent the key factors to determine the optimal timing of treatment of the aortic injury and guide the overall treatment strategy.

Abstract
OBJECTIVE The objective was to characterize the growing body of literature regarding nonoperative management of blunt thoracic aortic injury (BTAI). METHODS A systematic search of MedLine, Embase, and Cochrane Central was completed to identify original articles reporting injury characteristics and outcomes in patients with BTAI managed nonoperatively during their index hospitalization. Article title and abstract screening, full-text review, and data abstraction were performed in duplicate, with discrepancies resolved by a third reviewer. The quality of each study was evaluated using the Oxford Centre for Evidence-Based Levels of Evidence. RESULTS Of 2162 identified studies, 74 were included and reported on 8606 patients with BTAI who were managed nonoperatively between 1970 and 2016. Only one study was prospective. The median nonoperative sample size per study was 11 patients. The characterization of aortic injury grade differed across studies. Follow-up varied widely from 1 day to 118 months. Injury healing or improvement on follow-up imaging occurred in 34% (226 of 673 patients; reported in 37 studies), most often in the context of grade I intimal injury. Injury progression or requirement for a thoracic endovascular aneurysm repair for injury progression was 7.6% (66 of 873 patients; reported in 46 studies). A total of 37 studies reported aortic-related death, with an overall rate of 4.5% (37 of 827 patients) and a rate of 1% in grade I and II injuries (1 of 153 patients) and 18% in grade III and IV (9 of 50 patients). CONCLUSIONS An increasing number of reports support nonoperative management of grade I intimal injury, consistent with Society for Vascular Surgery guidelines. However, a retrospective interpretation of the determinants of management, heterogeneous injury characterization, and variable follow-up remain major limitations to the informed use of nonoperative management across all BTAI grades.

Abstract
Blunt thoracic aortic injury (BTAI) represents an infrequently encountered but lethal traumatic injury. Minimal aortic injuries are appropriately treated by medical management, while more severe injuries require endovascular or open repair. Rapidly evolving endovascular technology has largely supplanted open repair as first line operative intervention, however, the complexity of the severely injured blunt trauma patient can complicate management decisions. The development and implementation of an optimal consensus grading system and treatment algorithm for the management of BTAI is necessary and will require multi-institutional study.

Abstract
Aortic injury remains a major contributor to morbidity and mortality from acute thoracic trauma. While such injuries were once nearly uniformly fatal, the advent of cross-sectional imaging in recent years has facilitated rapid diagnosis and triage, greatly improving outcomes. In fact, cross-sectional imaging is now the diagnostic test of choice for traumatic aortic injury (TAI), specifically computed tomography angiography (CTA) in the acute setting and CTA or magnetic resonance angiography (MRA) in follow-up. In this review, we present an up-to-date discussion of acute traumatic thoracic aortic injury with a focus on optimal and emerging CT/MR techniques, imaging findings of TAI, and potential pitfalls.

Abstract
Aortic trauma is a devastating injury often associated with significant polytrauma. Penetrating injury of the aorta is highly lethal and therefore rarely encountered in the hospital setting. The management of blunt trauma of the aorta has changed significantly over the past decade, principally due to improved imaging technology and the development of endovascular therapy. The most common site of injury is the proximal descending thoracic aorta. The degree of aortic wall injury guides the indication for therapy, while a combination of the degree of injury and the extent of co-morbid injuries drives the timing of repair. Lower grade injuries frequently do not require any surgical intervention. Thoracic aortic endograft repair can be performed in a safe, expeditious fashion. Short-term and mid-term outcomes appear excellent, with patient survival based mainly on concomitant traumatic injuries. Long-term outcomes are less well known. Future endeavors will be guided toward gaining a better understanding of the indications for repair and the long-term outcomes for endograft devices designed for this purpose.

Abstract
Background We assess the effectiveness and our experience in emergency thoracic endovascular aortic repair (TEVAR) in patients with post-traumatic acute thoracic aortic injury (TAI) and associated multiorgan trauma. TAI is a life-threatening condition. It usually results from a sudden deceleration caused by vehicle accident, a fall or some other misfortune. Techniques of endovascular aortic repair have become promising methods to treat emergent TAI. Methods Since 2007, 114 patients with thoracic aorta pathologies have been treated by TEVAR. Our study involved 15 (incl. 14 men) of them (13%) who underwent stent graft implantation for post-traumatic either aortic rupture or pseudoaneurysm. The procedural access was limited to small skin incision in one groin and percutaneous puncture of the contralateral femoral artery. We evaluated technical success, early and long-term mortality, complication rate of procedure and throughout clinical and instrumental follow-up. Results Technical success rate was 100%. All patients survived the endovascular interventions. No additional procedures or conversions to open surgery were necessary. After the operation, none of the patients had symptoms of stroke or spinal cord ischemia (SCI). No serious stent-graft-related adverse events such as endoleak, infection or migration were noted during follow-up period that ranged from 6 to 108 months. Conclusions In our department, techniques of TEVAR with stentgraft implantation have become methods of choice in treatment of traumatic TAIs since they have enabled to minimize operational risk, particularly in unstable multitrauma patients in severe clinical status. TEVAR for TAI performed in emergency settings provide favorable long-term results.

Abstract
Acute aortic pathologies include acute aortic syndrome (aortic dissection, intramural hematoma, penetrating aortic ulcer), impending rupture, aortic aneurysm rupture and aortic trauma. Acute aortic syndrome, aortic aneurysm rupture and aortic trauma are life-threatening conditions requiring prompt diagnosis and treatment. The basic imaging modality for "acute aorta" is CT angiography with typical findings for these aortic pathologies. Based on the CT, it is possible to classify aortic diseases and anatomical classifications are essential for the planning of treatment. Currently, endovascular treatment is the method of choice for acute diseases of the descending thoracic aorta and is increasingly indicated for patients with ruptured abdominal aortic aneurysms.

Abstract
Purpose Traumatic aortic injury (TAI) is a rare but life-threatening type of injury. We investigate whether the anatomy of the aortic arch influences the severity of aortic injury. Methods This is a retrospective study of twenty-two cases treated with TEVAR for TAI in our department from 2009 to 2014. Aortic injury was assessed in accordance with the recommendations of the Society of Vascular Surgery. We measured the aortic arch angle and the aortic arch index, based on the initial angio-CT scan, in each of the analyzed cases. Results The mean aortic arch index and mean aortic arch angle were 6.8 cm and 58.3°, respectively, in the type I injury group; 4.4 cm and 45.9° in the type III group; 3.3 cm and 37° in the type IV group. There were substantial differences in both the aortic arch index and the aortic arch angle of the type III and IV groups. A multivariate analysis confirmed that the aortic arch angle was significantly associated with the occurrence of type III damage (OR 1.5; 95% CI 1.03–2.2). Conclusions The severity of TAI is influenced by the sharpness of the aortic arch. There is an inverse relationship between the severity of aortic injury and the aortic arch index.

Abstract
BACKGROUND Current blunt thoracic aortic injury (BTAI) guidelines recommend early repair of traumatic pseudoaneurysms (PSAs) due to risk for subsequent aortic rupture. Recent analyses indicate that early repair is required only in the setting of high-risk features, while delayed repair is safe and associated with lower morbidity and mortality in appropriately selected patients. To evaluate the appropriate indications for nonoperative management (NOM) of traumatic PSAs, we performed a systematic review of studies reporting outcomes for this management strategy. We hypothesized that NOM is safe in appropriately selected patients with traumatic aortic PSAs. METHODS English language single- and multi-institutional series reporting NOM of traumatic thoracic aortic PSAs were identified by systematic literature search and review. A descriptive analysis was performed of NOM, with stratification by lesion size and patient follow-up. The primary outcomes were late aortic intervention, aortic-related death, and all-cause mortality. RESULTS Eighteen studies, which included 937 patients with traumatic PSAs, were analyzed. One hundred ninety-one patients were managed nonoperatively. The primary indication for NOM was prohibitive risk for aortic repair due to severe comorbidities or concurrent injuries. Where reported, PSAs with <50% circumferential involvement accounted for 88% of lesions selected for NOM. Late interventions were required in 4% of patients. Inpatient aortic-related mortality was 2%, and all-cause inpatient mortality was 32%. Although survival at up to 4-7 years was reported, postdischarge follow-up after PSA NOM was limited to <1 year in most studies. CONCLUSIONS NOM of traumatic aortic PSAs is a common practice in BTAI series reporting lesion-specific management, and is associated with low rates of treatment failure. These findings suggest that routine early repair may not be required for traumatic PSAs, particularly for lesions limited to <50% of the aortic circumference. Definitive repair can be delayed until patient stability and repair timing can be guided by assessment of lesion stability on follow-up imaging.

Toward Reduction of Post-Hospital Admission Death Rate Caused by Acute Traumatic Aortic Tear. J Emerg Med 2016; 51:114-9.

Abstract
BACKGROUND Terminology and classifications are the vehicles by which pathologic conditions are identified and understood. It is critically important for the patient admitted with suspected blunt thoracic aortic injury that admitting physicians have a thorough knowledge of acute traumatic aortic tear and its natural history. OBJECTIVES The objectives of this review were as follows: (1) to introduce a pathology-based terminology and classification of acute traumatic aortic injuries that unambiguously defines each, and (2) to emphasize the clinical relevance of acute traumatic tear to post-hospital admission deaths in blunt thoracoabdominally injured patients. METHODS This is a literature review of 32 refereed articles pertaining to acute traumatic thoracic aortic injury published from 1957 to the present. RESULTS The terminology used to describe aortic injury is inconsistent. Several terms are often loosely interchanged: tear, laceration, transection, and rupture. Furthermore, classifications of aortic injuries have been proposed based on microscopic or gross pathologic or computed tomography scan results. While microscopically-based classifications have little or no clinical application, a classification based on gross pathology provides information useful for aortic injury prognosis and management. CONCLUSION Reduction of post-hospital death caused by acute aortic tear requires knowledge and understanding of the pathology of acute traumatic aortic tear and its natural history. Such understanding of pathology of acute traumatic aortic tear and its natural history is enhanced by terminology that defines the aortic injury. Therefore, we present our proposed terminology and classification of acute traumatic injuries.

Abstract
OBJECTIVE The current Society for Vascular Surgery (SVS) classification scheme for blunt aortic injury (BAI) is descriptive but does not guide therapy. We propose a simplified classification scheme based on our robust experience with BAI that is descriptive and guides therapy. METHODS Patients presenting with BAI between January 1999 and September 2014 were identified from our institution's trauma registry. We divided patients into eras by time. Era 1: before the first United States Food and Drug Administration (FDA)-approved thoracic endovascular aortic repair (TEVAR) device (1999-2005); era 2: FDA-approved TEVAR devices (2005-2010); and era 3: FDA-approved BAI-specific devices (2010-present). Baseline demographic information, Injury Severity Score, hospital details, and survival were collected and compared. Our classification scheme was minimal aortic injury, SVS grade 1 and 2; moderate aortic injury, SVS grade 3; and severe aortic injury, SVS grade 4. RESULTS We identified 226 patients with a diagnosis of BAI: 75 patients in era 1, 84 in era 2, and 67 in era 3. Mean Injury Severity Score was 39.5 (range, 16-75). The BAI-related in-hospital mortality was significantly higher before endovascular introduction in era 1 (14.6% vs 4.8%; P = .03), but was not significantly different between eras 2 and 3 or before and after BAI-specific devices were introduced (P = .43). Of 146 patients (64.6%) who underwent aortic intervention, 91 underwent endovascular repair, and 55 underwent open repair. All but nine patients (94%) had a moderate or severe injury. Survival across all three eras of patients undergoing operative intervention was 80.2%. Survival in eras 2 and 3 was higher than in era 1 (86.4% vs 73.8%) but was not significant (P = .38). Of 47 patients in eras 2 and 3 with minimal aortic injury, 45 (96%) were managed nonoperatively, with no BAI-related deaths. After 2007, follow-up imaging was obtained in 38 patients (80%) with minimal aortic injury, and progression was not observed. Computed tomography scans showed the injury in 13 patients appeared stable, 19 had complete resolution (50%), and 6 had a decreasing size of injury. CONCLUSIONS Our experience confirms that BAI-related mortality for patients who survive to presentation is now 5%. From our findings during the past 15 years, we propose simplification of the SVS grading criteria of BAI into minimal, moderate, and severe based on treatment differences among the three groups. Minimal aortic injury can be successfully managed nonoperatively without mandatory follow-up imaging. Moderate aortic injury can be managed semielectively with TEVAR, and severe aortic injury, requires emergency TEVAR.

Abstract
Background: Multiple classifications can be used to define the magnitude of aortic injury. The Vancouver Classification (VC) is a new and simplified computed tomography-based Blunt Aortic Injury (BAI) grading system correlating with clinical outcomes. Objectives: The objectives of this study are: 1) to describe the severity of aortic injury in a center with a predominantly surgical approach to BAI; 2) to correlate the severity of aortic trauma to hospital survival rate and rate of adverse events according to the type of interventions performed during the hospital stay; and 3) to evaluate VC. Patients and Methods: All patients referring to the Sacre-Coeur Hospital of Montreal between August 1998 and April 2011 for management of BAI were studied. Two radiologists reviewed all CT scan images individually and classified the aortic injuries using VC. Results: Among the 112 patients presenting with BAI, 39 cases had local CT scans available for reconstruction. Seven patients were identified as suffering from grade I injuries (flap or thrombus of less than 1 cm), 6 from grade II injuries (flap or thrombus of more than 1 cm), and 26 from grade III injuries (pseudoaneurysm). Among the patients with grade I injuries, 57% were treated surgically and 43% medically with a survival rate of 100%. Among the patients with grade II injuries (67% treated surgically and 33% treated medically) survival was also 100%. Among patients with grade III injuries (85% treated surgically, 7% had Thoracic Endovascular Aortic Repair (TEVAR) and 8% treated medically) survival was 95%, 95% and 50%, respectively. There were no significant differences between groups as to clinical outcome. Inter-rater reliability was 0.81. Conclusions: VC is easy to use and has low inter-observer variability. Low grades of injury were associated with low mortality related to medical treatment.

MDCT distinguishing features of focal aortic projections (FAP) in acute clinical settings. Radiol Med 2014; 120:50-72.

Abstract
Focal aortic projections (FAP) are protrusion images of the contrast medium (focal contour irregularity, breaks in the intimal contour, outward lumen bulging or localized blood-filled outpouching) projecting beyond the aortic lumen in the aortic wall and are commonly seen on multidetector computed tomography (MDCT) scans of the chest and abdomen. FAP include several common and uncommon etiologies, which can be demonstrated both in the native aorta, mainly in acute aortic syndromes, and in the post-surgical aorta or after endovascular therapy. They are also found in some types of post-traumatic injuries and in impending rupture of the aneurysms. The expanding, routine use of millimetric or submillimetric collimation of current state-of-the-art MDCT scanners (16 rows and higher) all the time allows the identification and characterization of these small ulcer-like lesions or irregularities in the entire aorta, as either an incidental or expected finding, and provides detailed three-dimensional pictures of these pathologic findings. In this pictorial review, we illustrate the possible significance of FAP and the discriminating MDCT features that help to distinguish among different types of aortic protrusions and their possible evolution. Awareness of some related and distinctive radiologic features in FAP may improve our understanding of aortic diseases, provide further insight into the pathophysiology and natural history, and guide the appropriate management of these lesions.

Abstract
The aim of this study is to describe the frequency, computed tomographic angiography (CTA) imaging appearance, management, and outcome of patients who present with minimal thoracic aortic injury. This retrospective study was Institutional Review Board-approved. Eighty-one patients with blunt traumatic aortic injuries (BTAI) were identified between 2004 and 2008, comprising 23 patients with minimal aortic injury (MAI) (mean age, 43.2 years ±18.2 years; 12 males and 11 females) and 58 patients with non-minimal aortic injury (mean age, 42.6 years ±22.7 years). CTA imaging was reviewed for each patient to differentiate those with MAI from those with non-MAI BTAI. Inclusion criteria for MAI on CTA were: post-traumatic abnormality of the internal contour of the aorta wall projecting into the lumen, intimal flap, intraluminal filling defect, intramural hematoma, and no evidence of an abnormality to the external contour of the aorta. Relevant follow-up imaging for MAI patients was also reviewed for resolution, stability, or progression of the vascular injury. The electronic medical record of each patient was reviewed and mechanism of injury, injury severity score, associated injuries, type and date of management, outcome, and days from injury to last medical consultation. Minimal aortic injury represented 28.4 % of all BTAI over the study period. Mean injury severity score (37.1), age (43.2 years), and gender did not differ significantly between MAI and non-MAI types of BTAI. Most MAI occurred in the descending thoracic aorta (16/23, 69 %). Without operative or endovascular repair, there was no death or complication due to MAI. One death occurred secondary to MAI (4.4 %) in a patient who underwent endovascular repair and surgical bypass, compared with an overall mortality rate of 8.6 % in the non-MAI BTAI group (p = 0.508). The most common CT appearance of MAI was a rounded or triangular intra-luminal aortic filling detect (18/23 patients, 78 %). In a mean of 466 days of clinical follow-up, no complications were observed in survivors treated without endovascular repair or operation. Minimal aortic injury is identified by multi-detector row CT in more than a quarter of cases of BTAI and has a low mortality. Conservative management is associated with an excellent outcome.
