Abstract
PURPOSE Most blunt thoracic aortic injuries (BTAIs) may be treated using thoracic endovascular aortic repair (TEVAR), and most blunt abdominal traumas (BATs) are managed conservatively. We hypothesized that severe trauma that needs TEVAR may increase the risk of delayed intra-abdominal hemorrhage in patients with concomitant BTAI and BAT because of the potential hemorrhagic shock, disseminated intravascular coagulopathy, blood loss, consequent need for blood transfusion, and procedure-associated heparinization. MATERIALS AND METHODS From 2015 to 2019, blunt trauma patients with concomitant severe chest trauma and abdominal trauma who could be managed conservatively were studied. The probability of delayed intra-abdominal hemorrhage was compared between patients with concomitant BTAI who received or did not undergo TEVAR. Propensity score matching (PSM), inverse probability of treatment weighting (IPTW), and multivariate logistic regression (MLR) were used to eliminate discrepancies between these 2 groups. RESULTS Among the 341 studied patients, there were 26 patients with BTAI, and 19 of them underwent TEVAR. Delayed intra-abdominal hemorrhage was observed in 4 patients (21.1%, 4/19) who underwent TEVAR. Both PSM and IPTW showed that patients who underwent TEVAR for concomitant BTAI had a greater delayed need for blood transfusions and a larger proportion of delayed intra-abdominal hemorrhage than patients who did not undergo the procedure. The MLR analysis showed that TEVAR for BTAI was an independent risk factor for delayed intra-abdominal hemorrhage (odds ratio: 10.534, 95%, p<0.001). CONCLUSION An increased probability of delayed intra-abdominal hemorrhage in patients with BAT (who could be managed conservatively) was observed in patients who underwent TEVAR for concomitant BTAI. CLINICAL IMPACT More attention should be give in patients with high grade aortic injuries and concomitant abdominal trauma.

Abstract
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. This study included data from all patients aged 18 and up who had been diagnosed with BTAI and had undergone TEVAR. The BTAI diagnoses were confirmed using CT scans. Logistic regression was utilized to identify predictors of patients' health status improvement and length of stay. RESULTS A total of 80 patients were involved. Around 50.0% (n=40) of the patients had grade 3 thoracic aortic injuries. The median duration of stay was 14.00 days (Interquartile range 21.00). Only one patient developed post-procedure complications (1.3%). Almost one-third (31.3%; n=25) of the patients required subclavian coverage. One patient developed intraoperative endoleak (1.3%). One patient developed an access site complication (1.3%). The mortality rate within 30 days of the operation was 1.3%. The vast majority of the patients (92.5%; n=74) showed improvement upon discharge from the hospital. The baseline patient characteristics and length of hospitalization had no effect on the improvement of patient status upon discharge or their length of stay (p>0.05). CONCLUSION Patients with BTAI have shown an excellent success rate with TEVAR and a low complication rate. Predictors of procedure success and length of stay need to be identified; however, this can't be done without larger-scale investigations. This can aid in the development of preventative measures that improve clinical outcomes for the patients.

The Characteristics and Results of Endovascular Devices in Trauma (CREDiT) study: Multi-institutional results. Injury 2023:S0020-1383(23)00285-1. [PMID: 37005135 DOI: 10.1016/j.injury.2023.03.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 01/24/2023] [Accepted: 03/20/2023] [Indexed: 04/04/2023]
Abstract
INTRODUCTION Endovascular techniques are increasingly used to repair major traumatic vascular injuries, but most endovascular implants are not designed/approved for trauma-specific indications. No inventory guidelines exist for the devices used in these procedures. We aimed to describe the use and characteristics of endovascular implants used for repair of vascular injuries to allow for better inventory management. METHODS This CREDiT study is a six-year retrospective cohort analysis of endovascular procedures performed for repair of traumatic arterial injuries at five participating US trauma centers. For each treated vessel, procedural and device details were recorded and outcomes assessed with the aim of defining the range of implants and sizes used for these interventions. RESULTS A total of 94 cases were identified; 58 (61%) were descending thoracic aorta, 14 (15%) axillosubclavian, 5 carotid, 4 abdominal aortic, 4 common iliac, 7 femoropopliteal, and 1 renal. Vascular surgeons performed 54% of cases, trauma surgeons 17%, IR/CT Surgery 29%. Systemic heparin was administered in 68% and procedures were performed a median of 9 h after arrival (IQR 3-24 h). Primary arterial access was femoral in 93% of cases, 49% were bilateral. Brachial/radial access was used primarily in 6 cases, and secondary to femoral in 9. The most common implant was self-expanding stent graft; 18% used >1 stent. Implants ranged in diameter and length based on vessel size. Five of 94 implants underwent reintervention (1 open surgery) at a median of 4d postop (range 2-60d). Two occlusions and 1 stenosis were present at follow-up at a median of 1 month (range 0-72 m). CONCLUSIONS Endovascular reconstruction of injured arteries requires a broad range of implant types, diameters, and lengths which should be readily available in trauma centers. Stent occlusions/stenoses are rare and can typically be managed by endovascular means.

Female sex is independently associated with reduced inpatient mortality after endovascular repair of blunt thoracic aortic injury. J Vasc Surg 2023; 77:56-62. [PMID: 35944732 DOI: 10.1016/j.jvs.2022.07.178] [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: 02/18/2022] [Revised: 06/21/2022] [Accepted: 07/19/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND Female sex has been associated with decreased mortality after blunt trauma, but whether sex influences the outcomes of thoracic endovascular aortic repair (TEVAR) for traumatic blunt thoracic aortic injury (BTAI) is unknown. METHODS In this retrospective study of a prospectively maintained database, the Vascular Quality Initiative registry was queried from 2013 to 2020 for patients undergoing TEVAR for BTAI. Univariate Student's t-tests and χ2 tests were performed, followed by multivariate logistic regression for variables associated with inpatient mortality. RESULTS Of 806 eligible patients, 211 (26.2%) were female. Female patients were older (47.9 vs 41.8 years, P < .0001) and less likely to smoke (38.3% vs 48.2%, P = .044). Most patients presented with grade III BTAI (54.5% female, 53.6% male), followed by grade IV (19.0% female, 19.5% male). Mean Injury Severity Scores (30.9 + 20.3 female, 30.5 + 18.8 male) and regional Abbreviated Injury Score did not vary by sex. Postoperatively, female patients were less likely to die as inpatients (3.8% vs 7.9%, P = .042) and to be discharged home (41.4% vs 52.2%, P = .008). On multivariate logistic regression, female sex (odds ratio [OR]: 0.05, P = .002) was associated with reduced inpatient mortality. Advanced age (OR: 1.06, P < .001), postoperative transfusion (OR: 1.05, P = .043), increased Injury Severity Score (OR: 1.03, P = .039), postoperative stroke (OR: 9.09, P = .016), postoperative myocardial infarction (OR: 9.9, P = .017), and left subclavian coverage (OR: 2.7, P = .029) were associated with inpatient death. CONCLUSIONS Female sex is associated with lower odds of inpatient mortality after TEVAR for BTAI, independent of age, injury severity, BTAI grade, and postoperative complications. Further study of the influence of sex on postdischarge outcomes is needed.

Delayed Endovascular Repair With Procedural Anticoagulation: A Safe Strategy for Blunt Aortic Injury. Ann Vasc Surg 2022; 84:195-200. [PMID: 35247536 DOI: 10.1016/j.avsg.2022.01.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/13/2022] [Accepted: 01/19/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Blunt aortic injury (BAI) and traumatic brain injury (TBI) are the leading causes of death after blunt trauma. The purposes of this study were to identify predictors of mortality for BAI and to examine the impact of procedural heparinization during thoracic endovascular aortic repair (TEVAR) on neurologic outcomes in patients with BAI/TBI. METHODS Patients with BAI were identified over an 8 year period. Age, gender, severity of injury and shock, time to TEVAR, morbidity, and mortality were recorded and compared. Multivariable logistic regression (MLR) was performed to determine independent predictors of mortality. Youden's index determined optimal time to TEVAR. RESULTS A total of 129 patients were identified. The majority (74%) were male with a median age and injury severity score (ISS) of 40 years and 29, respectively. Of these, 26 (20%) had a concomitant TBI. Patients with BAI/TBI had higher injury burden at presentation (ISS 37 vs. 29, P = 0.002; Glasgow Coma Scale [GCS] 6 vs. 15, P < 0.0001), underwent fewer TEVAR procedures (31 vs. 53%, P = 0.039), and suffered increased mortality (39 vs. 16%, P = 0.009). All TEVARs had procedural anticoagulation, including patients with TBI, without change in neurologic function. The optimal time to TEVAR was 14.8 hr. Mortality increased in TEVAR patients before 14.8 hr (8.7 vs. 0%, P = 0.210). MLR identified TEVAR as the only modifiable factor that reduced mortality (odds ratio 0.11; 95% confidence interval 0.03-0.45, P = 0.002). CONCLUSIONS TEVAR use was identified as the only modifiable predictor of reduced mortality in patients with BAI. Delayed TEVAR with the use of procedural heparin provides a safe option regardless of TBI with improved survival and no difference in discharge neurologic function.
