TEVAR

BACKGROUND: Obesity is a well-known predictor for poor postoperative outcomes of vascular surgery. However, the association between obesity and outcomes of thoracic endovascular aortic repair (TEVAR) is still unclear. This systematic review and meta-analysis was performed to assess the roles of obesity in the outcomes of TEVAR. METHODS: We systematically searched the Web of Science and PubMed databases to obtain articles regarding obesity and TEVAR that were published before July 2023...

OBJECTIVES: Non-A non-B aortic dissection (AD) is a rare and life-threatening medical emergency, and it has been controversial whether it should be managed as type B aortic dissection (TBAD). The study aims to compare in-hospital and follow-up outcomes between patients with non-A non-B AD and those with TBAD treated by endovascular based treatment (EBT). METHODS: From January 2017 to December 2021, 96 consecutive patients with non-A non-B AD met the inclusion criteria and underwent EBT...

PURPOSE: This study aimed to construct a predictive model integrating deep learning-derived radiomic features from computed tomography angiography (CTA) and clinical biomarkers to forecast postoperative adverse events (AEs) in patients with acute uncomplicated Stanford type B aortic dissection (uTBAD) undergoing initial thoracic endovascular aortic repair (TEVAR). METHODS: We retrospectively evaluated 369 patients treated with TEVAR for acute uTBAD from January 2015 to December 2022...

OBJECTIVES: Thoracic endovascular aneurysm repair (TEVAR) is widely used for the treatment of aortic dissection. Endograft oversizing is a risk factor for stent graft-induced new entry tears and retrograde type A aortic dissection. However, there is no clear consensus on the optimal graft size selection for Stanford type B acute or subacute aortic dissection (TBAD). Herein, we examined the safety and efficacy of TEVAR using an intentionally undersized endograft to treat TBAD. METHODS: This retrospective chart review study included 82 patients who underwent TEVAR for acute or subacute Stanford TBAD between 2015 and 2022...

INTRODUCTION: The risk of radiation exposure in the surgical operating room (OR) and/or cathlab is now well established. Complex endovascular procedures often require multiple approaches and different positioning of the staff members around the patient, potentially increasing the levels of radiations exposure. Our goal was to evaluate the levels of radiation exposure of the members of the staff during endovascular aortic procedures in order to propose radioprotection optimization. MATERIAL AND METHODS: We included 41 aortic endovascular procedures out of 114 procedures performed between 12/01/2014 and 31/08/2015 including 24 standard endovascular aortic aneurysm repair (EVAR), 7 EVAR with iliac branch (EVARib), 8 complex fenestrated/branched EVAR (F/B EVAR), 2 Thoracic EVAR (TEVAR)...

BACKGROUND: Aortoesophageal fistula (AEF) is a rare but potentially life-threatening condition. The best treatment for the AEF due to esophageal carcinoma is still unresolved. Here, we report a rare case of AEF caused by esophageal cancer, that was successfully treated with emergency thoracic endovascular aortic repair (TEVAR), followed by esophagectomy and gastric tube reconstruction. CASE PRESENTATION: A 64-year-old man presented with loss of consciousness and hypotension during chemoradiotherapy for advanced esophageal cancer...

INTRODUCTION: Endovascular treatment of type B aortic dissections (TBAD) has currently acquired a primary therapeutic role when anatomically feasible. The main issue with thoracic endovascular aortic repair (TEVAR) for aortic dissection is the actual nature of the aortic wall, which is structurally compromised and more fragile. Indeed, a wealth of data have shown that TEVAR for TBAD will lead, in a substantial proportion of cases, to a device-related adverse event named distal stent-graft induced new entry (dSINE)...

Thoracic endovascular aortic repair (TEVAR) of acute uncomplicated type B aortic dissection (uTBAD) has been discussed for its potential to prevent future aortic events. We present a fenestrated TEVAR in the case of an 86-year-old man with acute uTBAD with an isolated left vertebral artery (ILVA). The ILVA originated from the distal side of the left subclavian artery, the left subclavian artery, and the intramural hematoma with an ulcer-like projection extended close to the left subclavian artery. We selected a fenestrated stent graft to achieve a proximal healthy landing...

The patient was a 48-year-old man who had undergone fenestrated frozen elephant trunk (FET) technique for acute type A aortic dissection. Postoperative enhanced computed tomography (CT) imaging revealed a type 1a endoleak from the fenestration. Nevertheless, the stented portion of the FET exhibited circular expansion. However, 2 months after surgery, enhanced CT imaging revealed the flattening of the FET due to the persistent endoleak and we performed an urgent zone 2 thoracic endovascular aortic repair (TEVAR)...

PURPOSE: This systematic review aimed to summarize the effectiveness and safety of endoanchor, a stabilizing device for the proximal endograft designed to prevent endoleak and stent migration in endovascular aneurysm repair (EVAR) and thoracic endovascular aneurysm repair (TEVAR). MATERIALS AND METHODS: A systematic review and meta-analysis was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline. Literature up to May 31, 2023 was searched and independently screened from 4 databases...

OBJECTIVE: As it remains unclear whether there are sex-based differences in clinical outcomes after thoracic endovascular aortic repair (TEVAR), this meta-analysis aimed to evaluate differences in early outcomes and overall survival between female and male patients who underwent TEVAR. METHODS: PubMed, Embase, Web of Science, and Cochrane Central databases were searched for eligible studies published through June 10, 2023, that reported sex-based differences in clinical outcomes after TEVAR...

Although thoracic endovascular repair (TEVAR)-specific complications often develop, stent-graft collapse is a rare, but fatal complication that requires attention. A 62-year-old male underwent TEVAR for a saccular distal arch aortic aneurysm. After the placement of the Gore TAG (W. L. Gore & Associates, Inc., Newark, DE, USA) from zones 2 to 4, a Najuta endograft (Kawasumi Laboratories, Inc., Tokyo, Japan) was deployed from zone 0. Neither intraoperative angiography nor postoperative contrast-enhanced computed tomography (CT) showed endoleaks or migration...

BACKGROUND: The triglyceride-glucose (TyG) index and triglyceride to high-density lipoprotein cholesterol (TG/HDL-c) ratio are both reliable surrogate indicator of insulin resistance and have been shown to be valuable in predicting various cardiovascular diseases. However, few studies have explored its association with the prognosis of type B aortic dissection (TBAD) patients receiving thoracic endovascular aortic repair (TEVAR). METHODS: A total of 1,425 consecutive patients who underwent TEVAR were included...

OBJECTIVE: It is estimated that 22 - 57% of vascular patients are lost to follow-up which is of concern as the Society of Vascular Surgery recommends annual patient follow-up. The purpose of this report was to identify social determinants of health factors (SDoH) and their relationship to loss to follow-up in vascular patients. METHODS: The methods employed were a systematic literature review of 29 empirical articles and a retrospective quality improvement report with 27 endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) patients at the University of Chicago...

Thoracic endovascular aortic repair (TEVAR) has been widely adopted as a standard for treating complicated acute and high-risk uncomplicated Stanford Type-B aortic dissections. The treatment redirects the blood flow towards the true lumen by covering the proximal dissection tear which promotes sealing of the false lumen. Despite advances in TEVAR, over 30% of Type-B dissection patients require additional interventions. This is primarily due to the presence of a persistent patent false lumen post-TEVAR that could potentially enlarge over time...

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: Hospital volume is associated with mortality after open aortic aneurysm repair. Fenestrated and branched endovascular aortic repair (B-FEVAR) has been increasingly used for repair of complex thoracoabdominal and juxtarenal aneurysms but evidence of a center-volume relationship is limited. We aimed to measure the association of center volume with in-hospital mortality, post-operative outcomes and 1-year survival following B-FEVAR. METHODS: Patients undergoing elective endovascular thoracoabdominal and complex abdominal aneurysm repair with branch intervention (2014-2021) listed within the national Vascular Quality Initiative Thoracic Endovascular Aortic Repair (TEVAR)/complex EVAR database were analyzed...

BACKGROUND: To investigate the clinical efficacy of Castor integrated branched aortic stent graft for the treatment of Stanford type B aortic dissection with insufficient anchoring area. METHODS: Retrospective analysis of clinical data of 26 patients with Stanford type B aortic dissection with insufficient anchoring region (<15 mm) treated by Castor branched aortic stent graft from September 2018 to June 2022 at Ganzhou People's Hospital, including 23 acute cases and 3 chronic cases...

The use of thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysm (TAA) and Stanford type B aortic dissection (TBAD) has been increasing; however, in terms of etiology, the differences of long term after TEVAR outcomes remain unexplored. Thus, we investigated etiology-specific long-term results of TEVAR for TAA and TBAD. A total of 421 TEVAR procedures were performed at our institution from July 2007 to December 2021; 249 TAA cases and 172 TBAD cases were included. Traumatic aortic dissection and aortic injury cases were excluded...
