BTAI

OBJECTIVE: This study aimed to assess the long-term outcomes in patients treated by thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injuries (BTAI). MATERIALS AND METHODS: From January 2010 to December 2019, this retrospective observational study was conducted at 3 centers, involving 62 consecutive BTAI patients who underwent TEVAR. Computed tomography angiography scans were planned to be conducted at 6 months post-procedure, and annually thereafter...

BACKGROUND: Blunt traumatic aortic injury (BTAI) is a rare occurrence in adolescents, yet it is associated with a high mortality rate necessitating immediate treatment. Although endovascular repair has become the preferred treatment for such injuries in adults, its effectiveness in adolescents remains uncertain. CASE SUMMARY: Blunt traumatic aortic injury typically presents with concomitant injuries to other organs and carries a high perioperative mortality rate with operative repair (OR)...

BACKGROUND: Life-threatening blunt thoracic aortic injury (BTAI) typically occurs alongside multiple other traumatic injuries. Symptoms of BTAI can range from being asymptomatic in the case of intimal tears to becoming catastrophic in the case of uncontained aortic ruptures. The aim of this research was to examine the clinical outcomes for those who underwent thoracic endovascular aortic repair (TEVAR) in hospital settings.  Methods: A cross-sectional retrospective study was conducted using patient data that were extracted from Al-Noor Specialist Hospital, Makkah, Saudi Arabia, for the duration between January 2011 and December 2021...

INTRODUCTION: The optimal management of blunt thoracic aortic injury (BTAI) remains controversial, with experienced centers offering therapy ranging from medical management to TEVAR. We investigated the utility of a machine learning (ML) algorithm to develop a prognostic model of risk factors on mortality in patients with BTAI. METHODS: The Aortic Trauma Foundation registry was utilized to examine demographics, injury characteristics, management and outcomes of patients with BTAI...

OBJECTIVE: Endovascular repair of blunt thoracic aortic injury (BTAI) has dramatically reduced the morbidity and mortality of intervention. Injuries requiring zone 2 coverage of the aorta traditionally require left subclavian artery (LSA) sacrifice or open revascularization. Furthermore, these injuries are associated with increased risk of in-hospital mortality and long-term morbidity. Here we report 1-year outcomes of total endovascular repair of BTAI with the GORE® TAG® Thoracic Branch Endoprosthesis for LSA preservation...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) at high-volume hospitals has previously been associated with lower perioperative mortality, but the impact of annual surgeon volume on outcomes following TEVAR for BTAI remains unknown. METHODS: We analyzed Vascular Quality Initiative (VQI) data from patients with BTAI that underwent TEVAR between 2013-2023. Annual surgeon volumes were computed as the number of TEVARs (for any pathology) performed over a one-year period preceding each procedure and were further categorized into quintiles...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is the standard of care for the treatment of blunt thoracic aortic injuries (BTAI) requiring intervention. Data suggests that low grade BTAI (Grade 1 [intimal tears] or Grade 2 [intramural hematoma]) will resolve spontaneously if treated with non operative management (NOM) alone. There has been no comparison specifically between the use of NOM vs. TEVAR for low grade BTAI. We hypothesize that these low-grade injuries can be safely managed with NOM alone...

PURPOSE: Blunt thoracic aortic injury (BTAI) represents a potentially life-threatening condition and thoracic endovascular aortic repair (TEVAR) is recommended as the first-line treatment (Class I level of evidence C) by the current guidelines. The aim of this systematic review was to determine the perioperative and mid-term follow-up outcomes of patients with BTAI treated with TEVAR. MATERIALS AND METHODS: We reviewed the English literature published between 2000 and 2022, via Ovid, using MEDLINE, EMBASE, and CENTRAL databases, until July 30, 2022...

BACKGROUND: Blunt thoracic aortic injury (BTAI) is associated with a high mortality and is the second most common cause of death from trauma. The approach to major trauma, imaging technology and advancement in endovascular therapy have revolutionised the management of BTAI. Endovascular therapy has now become the gold standard technique replacing surgery with its high mortality and morbidity in unstable patients. We aim to assess the outcomes following management of BTAI. METHOD: This is a retrospective study of all patients with BTAI between 1 January 2010 and 1 January 2022...

PURPOSE: Thoracic endovascular aortic repair (TEVAR) is increasingly utilized to treat blunt thoracic aortic injury (BTAI), but post-discharge outcomes remain underexplored. We examined 90-day readmission in patients treated with TEVAR following BTAI. METHODS: Adult patients discharged alive after TEVAR for BTAI in the Nationwide Readmissions Database between 2016 and 2019 were included. Outcomes examined were 90-day non-elective readmission, primary readmission reasons, and 90-day mortality...

OBJECTIVE: Current societal recommendations regarding the timing of thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) vary. Prior studies have shown that elective repair was associated with lower mortality after TEVAR for BTAI. However, these studies lacked data such as Society for Vascular Surgery (SVS) aortic injury grades and TEVAR-related postoperative outcomes. Therefore, we used the Vascular Quality Initiative registry, which includes relevant anatomic and outcome data, to examine the outcomes following urgent/emergent (≤ 24 hours) vs elective TEVAR for BTAI...

Blunt thoracic aortic injury (BTAI) is fatal and requires thoracic endovascular aortic repair (TEVAR) for its optimal management. Performing TEVAR requires multidisciplinary specialists and supportive facilities.  We report a case of an 89-year-old man who presented to the emergency department with blunt trauma. Whole-body computed tomography (CT) revealed grade II aortic injury with disrupted blood flow to the left kidney. Sudden paralysis of the left lower extremity and distal progression of the aortic dissection occurred...

BACKGROUND: The objective of our present effort was to use an international blunt thoracic aortic injury (BTAI) registry to create a prediction model identifying important preoperative and intraoperative factors associated with postoperative mortality, and to develop and validate a simple risk prediction tool that could assist with patient selection and risk stratification in this patient population. METHODS: For the purpose of the present study, all patients undergoing thoracic endovascular aortic repair (TEVAR) for BTAI and registered in the Aortic Trauma Foundation (ATF) database from January 2016 as of June 2022 were identified...

Compared to widely adopted low-dimensional/three-dimensional (LD/3D) heterostructure, functional organic cation based surface termination on perovskite can not only realize advantage of defect passivation but also prevent potential disadvantage of the heterostructure induced intercalation into 3D perovskite. However, it is still very challenging to controllably construct surface termination on organic-inorganic hybrid perovskite because the functional organic cations' substitution reaction is easy to form LD/3D heterostructure...

INTRODUCTION: Calcification of a vascular endograft and adjacent tissues (adventitia, media, and neointima) can result in graft failure. This report shows a rare case of intraluminal calcifications in the distal end of a thoracic endovascular aortic repair (TEVAR) endograft implanted 11 years previously for grade IV blunt traumatic aortic injury (BTAI) in a young patient. REPORT: A 24 year old man required TEVAR for a BTAI caused by a motorcycle accident. The procedure consisted of TEVAR and an emergency left carotid subclavian venous bypass...

AIM: Blunt traumatic thoracic aortic injury (BTAI) is a highly fatal surgical emergency and is treated with endovascular procedures. We aimed to analyze and report the early and midterm outcomes of surgeon-modified fenestrated stent-grafts (SMFSG) compared with other conventional endovascular methods in patients with BTAI repaired with zone 2 endovascular surgery. MATERIALS AND METHODS: Before and after the study was performed, from January 2015 to January 2020 for a period in which conventional endovascular treatments were used and from January 2020 to January 2023 for the second period in which the SMFSG technique was used...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) in children and adolescents after blunt traumatic aortic injury (BTAI) is being performed increasingly despite no endovascular graft being approved for TEVAR in this population. The smaller diameter of the aorta and access vessels and steeper angle of the aortic arch pose specific challenges for TEVAR in this population. Moreover, data are lacking regarding medium to long term complications. This case presents an adolescent patient who underwent TEVAR for BTAI and suffered a focal aortic dissection several months later...

Blunt aortic injury is the second most prevalent cause of patient fatalities post-trauma, closely following head injuries as the leading cause. In recent years, thoracic endovascular aortic repair (TEVAR) has evidently improved survival rates and reduced complications in patients suffering from blunt traumatic aortic injury (BTAI) in comparison to open surgery and non-operative management. It is difficult to characterize the appropriate criteria for the timing of TEVAR, whether early or delayed for BTAI, considering the discrepancies related to timing...

OBJECTIVE: Blunt traumatic thoracic aortic injuries (BTAI) are associated with a high mortality rate. Thoracic endovascular aortic repair (TEVAR) is the most used surgical strategy in patients with BTAI, as it offers good short- and middle-term results. Previous studies have reported an abnormally-high prevalence of hypertension (HT) in these patients. This work aims to describe the long-term prevalence of HT and provide a comprehensive evaluation of the biomechanical, clinical and functional factors involved in HT development...

PURPOSE: This study presents analytic techniques to quantify cardiac pulsatility-induced deformations of thoracic aortic endografts in patients with thoracic aortic aneurysm (TAA), dissection (TAD), and blunt thoracic aortic injury (BTAI) after thoracic endovascular aortic repair (TEVAR). TECHNIQUE: We analyzed 19 image data sets from 14 patients treated for TAA, TAD, and BTAI with cardiac-gated post-TEVAR CTs. Systolic and diastolic geometric models were constructed and diametric, axial, and bending deformations were quantified...
