BTAI

<b/> Background: Thoracic endovascular aortic repair (TEVAR) is a well-established technique for the management of blunt thoracic aortic injury (BTAI). Despite improvements in vascular imaging, graft material properties, and implant techniques, stent-graft deployment artificially induces aortic stiffening. This study aimed to evaluate the midterm effect of thoracic endovascular aortic repair after blunt thoracic aortic injury on aortic stiffness and cardiac function in young patients using cardiovascular magnetic resonance (CMR) imaging...

A 30-year-old woman presented following a motor vehicle collision with a grade III blunt thoracic aortic injury and an aberrant right subclavian artery. Using intraoperative ultrasound and diagnostic subtraction angiography, we deployed an aortic endograft (cTAG; W.L. Gore & Associates), excluding the injury and aberrant right subclavian artery. The patient immediately lost arterial waveforms in her left arm, confirming incidental coverage of the left subclavian artery, likely due to the polytetrafluoroethylene sheath of the endograft...

Accounting for 1.5% of thoracic trauma, blunt thoracic aortic injury (BTAI) is a rare disease with a high mortality rate that nowadays is treated mostly via thoracic endovascular aortic repair (TEVAR). Personalised computational models based on fluid-solid interaction (FSI) principals not only support clinical researchers in studying virtual therapy response, but also are capable of predicting eventual outcomes. The present work studies the variation of key haemodynamic parameters in a clinical case of BTAI after successful TEVAR, using a two-way FSI model...

Blunt thoracic aortic injury (BTAI) is a potentially fatal condition that needs prompt recognition and expedited management. Clinical manifestations of BTAI are not straight forwarding and may be misdiagnosed. The grade of aortic injury is an important determinant of perioperative mortality and morbidity, as well as the indication of treatment, along with the presence of concomitant lesions of other involved organs. The mainstay of treatment nowadays for hemodynamically stable patients who survive the trauma scene is represented by delayed endovascular repair whenever anatomically and clinically feasible...

OBJECTIVE: Current literature suggests that thoracic endovascular aortic repair (TEVAR) in older patients with aortic aneurysms results in higher peri-operative mortality and lower long term survival in females compared with males. However, sex-related outcomes in younger patients with blunt thoracic aortic injury (BTAI) undergoing TEVAR remain unknown. This study examined the association between sex and outcomes after TEVAR for BTAI. METHODS: A retrospective cohort study was performed of all patients who underwent TEVAR for BTAI in the American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) between 2016 and 2019...

OBJECTIVE: Society for Vascular Surgery (SVS) recommendations for managing intimal (grade 1) blunt thoracic aortic injuries (BTAIs) include observation and medical management. University of Washington (UW) revised criteria suggest that intimal injuries with ≥1 cm flap should be upgraded to a moderate injury and treatment be considered. We sought to evaluate and compare SVS and UW criteria for BTAI and determine how discordance in grading affected treatment and outcome. METHODS: We reviewed all patients admitted with BTAI from January 1, 2011, to March 31, 2022...

PURPOSE: As blunt thoracic aortic injury (BTAI) treatment has shifted from open to thoracic endovascular aortic repair (TEVAR), logistical challenges exist in creating and maintaining inventories of appropriately sized stent-grafts, including storage demands, shelf-life management and cost. We hypothesized that most injured aortas can be successfully repaired with a narrow range of stent-graft sizes and present a value-based anatomic approach to optimizing inventory. METHODS: CT-scans of all patients with BTAI admitted to our Level I trauma center from Apr 2010-Dec 2018 were reviewed...

INTRODUCTION: Single branched thoracic endografts (SBTEs) have been designed for pathology requiring zone 2 seal during thoracic endovascular aortic repair (TEVAR). Numerous criteria must be met to allow for their implantation. Our aim was to analyze anatomic suitability for a next generation SBTE. METHODS: We reviewed 150 TEVAR procedures between 2015 and 2019. Proximal seal was: zone 0 in 21 (16%), zone 1 in 4 (3%), zone 2 in 52 (40%), zone 3 in 45 (35%), and zone 4 or distal in 7 (5%)...

OBJECTIVE: Although the Society of Vascular Surgery (SVS) aortic injury grading system is used to depict the severity of injury in blunt thoracic aortic injury (BTAI) patients, prior literature on its association with outcomes following thoracic endovascular aortic repair (TEVAR) is limited. METHODS: We identified patients undergoing TEVAR for BTAI within the VQI between 2013-2022. We stratified patients based on their SVS aortic injury grade (grade 1: intimal tear; grade 2: intramural hematoma; grade 3: pseudoaneurysm; and grade 4: transection/extravasation)...

OBJECTIVE: We examined early (≤24 h) versus delayed (>24 h) thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI), taking the aortic injury severity into consideration. BACKGROUND: Current trauma surgery guidelines recommend delayed TEVAR following BTAI. However, this recommendation was based on small studies, and specifics regarding recommendation strategies based on aortic injury grades are lacking. METHODS: Patients undergoing TEVAR for BTAI in the American College of Surgeons Trauma Quality Improvement Program between 2016 and 2019 were included and then stratified into 2 groups (early: ≤24 h vs...

OBJECTIVE: To investigate the long-term reinterventions of thoracic endovascular repair (TEVAR) after blunt traumatic aortic injury. METHODS: MEDLINE, EMBASE, and Cochrane databases were interrogated until June 2021. Inclusion criteria were blunt traumatic aortic injury treated with TEVAR and mean follow-up of more than 60 months. A systematic review was conducted and data were pooled using a random effects model of proportions applying the Freeman-Tukey transformation...

BACKGROUND: Elective Thoracic Endovascular Aortic Repair (TEVAR) with left subclavian artery coverage (LSA-C) without revascularization is associated with increased rates of ischemic stroke. In patients with blunt thoracic aortic injury (BTAI) requiring TEVAR, LSA-C is frequently required in over one-third of patients. This study aimed to evaluate outcomes of TEVAR in BTAI patients with and without LSA-C. METHODS: The largest existing international multicenter prospective registry of BTAI, developed and implemented by the Aortic Trauma Foundation, was utilized to evaluate all BTAI patients undergoing TEVAR from March 2016 to January 2021...

BACKGROUND: Traditional teaching continues to espouse the value of initial trauma chest x-ray (CXR) as a screening tool for blunt thoracic aortic injury (BTAI). The ability of this modality to yield findings that reliably correlate with grade of injury and need for subsequent treatment, however, requires additional multicenter prospective examination. We hypothesized that CXR is not a reliable screening tool, even at the highest grades of BTAI. STUDY DESIGN: The Aortic Trauma Foundation/American Association for the Surgery of Trauma prospective BTAI registry was used to correlate initial CXR findings to the Society for Vascular Surgery injury grade identified with computed tomographic angiography...

BACKGROUND: Traumatic aortic pseudoaneurysms (PSAs) classified as grade III aortic injuries are conventionally repaired as procedural emergencies, generally within 24 h of arrival. These patients typically require adequate resuscitation and treatment of multiple traumatic injuries, which complicate optimal management strategies of aortic PSAs. This study reviews the experience of an Asian single center to evaluate the efficacy and safety of delayed (> 24 h) endovascular repair for PSAs...

INTRODUCTION: Penetrating thoracic aortic injuries (PTAI) represent a rare form of thoracic trauma. Unlike blunt thoracic aortic injuries (BTAI), only scarce data, included in small case series, are currently available for PTAI. The purpose of this study was to describe injury patterns, surgical management, and outcomes of patients with PTAI and compare to those with BTAI. MATERIALS AND METHODS: A 9-y retrospective cohort study (2007-2015) was conducted using the National Trauma Data Bank...

Blunt thoracic aortic injuries (BTAI) are highly lethal, though their incidence is < 1%. The treatment options for BTAI have evolved over the years, where non-operative management is advised even in grade II injuries. In patients undergoing thoracic endovascular aortic repair, it is of vital importance that the left subclavian artery is revascularized. Many authors have opted for selective revascularization of the left subclavian artery in case of an emergency situation where the clinical condition of the patient is unstable...

PURPOSE: Blunt thoracic aortic injury (BTAI) has a high mortality rate, and the occurrence of clinical complications is high. Several studies have reported the efficacy of thoracic endovascular aortic repair (TEVAR) for BTAI. This study aimed to clarify the use of TEVAR for BTAI. METHODS: We analyzed 10 cases of TEVAR for BTAI from July 2011 to December 2020 at our hospital. Five of 10 cases of BTAI were caused by road traffic accidents, while five were caused by falls from a height...

OBJECTIVE: Prior literature has demonstrated worse outcomes in females following abdominal aortic aneurysm repair, and prior studies in context of thoracic endovascular aneurysm repair (TEVAR) for thoracic aortic aneurysm (TAA) have reported conflicting results regarding sex-related outcomes. As the influence of sex on outcomes following TEVAR for blunt thoracic aortic injuries (BTAI) remains understudied, we evaluated the association between sex and outcomes following TEVAR for BTAI...

BACKGROUND: Approximately 80% of patients with blunt thoracic aortic injury (BTAI) die before reaching the hospital. Most people who survive the initial injury eventually die without appropriate treatment. This study analyzed and reported the treatment strategy of a single center for BTAI in the last 10 years and the early and middle clinical results. METHODS: This retrospective study included patients diagnosed with BTAI at Xijing Hospital from 2013 to 2022. All inpatients with BTAI aged ≥ 18 years were included in this study...

BACKGROUND: Delayed thoracic aortic injury (DTAI) induced by left closed rib fractures (RFs) is a clinically rare blunt injury to the thoracic aorta with an insidious onset. DTAI is very prone to missed diagnosis due to the unreliability of using the initial post-injury computed tomography (CT) scan to explicitly detect any signs of an aortic injury, potentially leading to a fatal hemorrhage. Timely diagnosis and treatment are therefore key to preventing such deadly complications. With that said, not all cases of left RFs lead to delayed aortic injuries, so how can surgeons tell which cases are to be culled and focused on? Also, what kinds of treatment should be administered upon detection? METHODS: A retrospective analysis was performed on the clinical data of DTAI cases induced by left closed RF that were admitted to our Hospital from June 2015 through June 2020...
