Early outcomes of off-the-shelf Thoracoabdominal Multibranch Endoprosthesis during premaket vs postmarket approval periods.

Background: The Thoracoabdominal Multibranch Endoprosthesis (TAMBE, W. L. Gore & Associates) is the first off-the-shelf four-vessel inner-branched endograft to obtain commercial approval for complex abdominal and thoracoabdominal aortic aneurysms.

Outcomes following extended thoracic endovascular aortic repair for Type B aortic dissection from the global registry for endovascular aortic treatment.

Objectives: This study evaluated the short- to longer-term safety and efficacy of extended thoracic endovascular aortic repair for Type B aortic dissection.

Methods: We identified acute and subacute Type B dissection between 2010 and 2016 in the Global Registry for Endovascular Aortic Treatment. We stratified the population based on treatment extent: 'non-extended' (1 stent graft deployed), 'extended' (>1 stent graft deployed).

Early Thoracic Endovascular Aortic Repair for Acute Type B Dissection Is Associated with Increased Complications: Results from the Gore Global Registry for Endovascular Aortic Treatment Registry.

Background: Several recent small trials have suggested that there is a potential benefit of early thoracic endovascular aortic repair (TEVAR) for acute type B aortic dissection (TBAD), even for uncomplicated patients. We studied patients enrolled in the Gore Global Registry for Endovascular Aortic Treatment (GREAT) to compare outcomes of TEVAR in the early-acute phase with and without complicated presentation.

Methods: The GREAT registry was queried for patients treated with TEVAR for TBAD.

Contemporary outcomes of open thoracoabdominal aortic aneurysm repair in the endovascular era.

Objective: Open thoracoabdominal aortic aneurysm (TAAA) repair has been associated with high morbidity and mortality before the endovascular era, when repair options were limited. Our institution developed a multidisciplinary protocol to standardize patient selection, operative technique, and postoperative care to improve outcomes for open repairs. This study aimed to evaluate the protocol's preliminary benefits by comparing the outcomes of open TAAA repair on the protocol vs off the protocol.

Association of Chronic Obstructive Pulmonary Disease and Mortality Following Thoracic and Complex Endovascular Aortic Repair.

Background: This study assessed the association between chronic obstructive pulmonary disease (COPD) severity and postoperative mortality among patients undergoing thoracic endovascular aortic repair (TEVAR) and complex endovascular aortic repair (CEVAR).

Methods: A retrospective review of the Vascular Quality Initiative database identified elective TEVAR and CEVAR cases from 2013 to 2022, with endograft proximal landing zone ≥2 for thoracic or complex abdominal aortic disease. Symptomatic diseases, ruptures, and urgent or emergent surgeries were excluded.

Three-year outcomes of off-the-shelf Gore thoracoabdominal multibranch endoprosthesis and physician-modified endografts for complex abdominal and thoracoabdominal aortic aneurysms.

Objective: Fenestrated-branched endovascular aortic repair (FB-EVAR) has shown favorable outcomes for repair of complex aneurysms and thoracoabdominal aortic aneurysms. Physician-modified endografting (PMEG) and the Gore thoracoabdominal multibranch endoprosthesis (TAMBE) provide custom and off-the-shelf devices for FB-EVAR, respectively. This study compares the outcomes of TAMBE and PMEG at a single institution.

Baroreflex activation therapy in patients with heart failure and a reduced ejection fraction: Long-term outcomes.

Aims: Carotid baroreflex activation therapy (BAT) restores baroreflex sensitivity and modulates the imbalance in cardiac autonomic function in patients with heart failure with reduced ejection fraction (HFrEF). We tested the hypothesis that treatment with BAT significantly reduces cardiovascular mortality and heart failure morbidity and provides long-term safety and sustainable symptomatic improvement.

Methods And Results: BeAT-HF was a prospective, multicentre, randomized, two-arm, parallel-group, open-label, non-implanted control trial.

Prospective assessment of dynamic changes in frailty and its impact on early clinical outcomes following physician-modified fenestrated-branched endovascular repair of complex abdominal and thoracoabdominal aortic aneurysms.

Introduction: Frailty, a predictor of poor outcomes, has been widely studied as a screening tool in surgical decision-making. However, the impact of frailty on the outcomes after fenestrated-branched endovascular aortic repairs (FBEVARs) is less well established. In addition, the changes in frailty during recovery after FBEVAR are unknown.

Epidemiology, repair technique, and predictors of stroke and mortality in penetrating carotid artery injuries.

Objective: Penetrating carotid artery injuries (PCAI) are significantly morbid and deadly, often presenting in extremis with associated injuries and central nervous system deficit. Repair may be challenging with arterial reconstruction vs ligation role poorly defined. This study evaluated contemporary outcomes and management of PCAI.

Risk Factors for Cerebral Hyperperfusion Syndrome following Carotid Revascularization.

Background: Cerebral hyperperfusion syndrome (CHS) is a rare but known complication of carotid revascularization that can result in severe postoperative disability and death. CHS is a well-described sequela of carotid endarterectomy (CEA) and, more recently, of transfemoral carotid artery stenting (TFCAS), but its incidence after transcarotid artery revascularization (TCAR) has not been delineated. The aims of this study were to determine the impact of procedure type (CEA versus TCAR versus TFCAS) on the development of CHS as well as to identify perioperative risk factors associated with CHS.

Comparative outcomes of physician-modified fenestrated-branched endovascular repair of post-dissection and degenerative complex abdominal or thoracoabdominal aortic aneurysms.

Objective: Fenestrated-branched endovascular repair has become a favorable treatment strategy for patients with complex abdominal aortic aneurysms (cAAAs) and thoracoabdominal aortic aneurysms (TAAAs) who are high risk for open repair. Compared with degenerative aneurysms, post-dissection aneurysms can pose additional challenges for endovascular repair. Literature on physician-modified fenestrated-branched endovascular aortic repair (PM-FBEVAR) for post-dissection aortic aneurysms is sparse.

Risk of Stroke with Thoracic Endovascular Aortic Repair of the Aortic Arch.

Background: Thoracic endovascular aortic repair (TEVAR) involving the aortic arch is increasingly being performed and novel endografts have been developed for this procedure, but the association of stroke and relative risk of procedural techniques remains unclear. This study evaluates the procedural risk factors for stroke and mortality with zone 0-2 TEVAR.

Methods: The Society for Vascular Surgery Vascular Quality Initiative registry was queried for patients who underwent TEVAR with proximal landing in zone 0-2 from 2013 to 2022.

Selection criterion for endovascular aortic repair in those with chronic kidney disease.

Objective: Endovascular aortic repair (EVAR) is the preferred method of repair for abdominal aortic aneurysms (AAAs). However, patients with advanced chronic kidney disease (CKD) are a high-risk group, and it is unknown which patients with CKD benefit from EVAR vs continued surveillance. The purpose of this study was to identify which patients with advanced CKD may benefit from EVAR.

Transposition of anomalous left vertebral to carotid artery during the management of thoracic aortic dissections and aneurysms.

Objectives: Preservation of antegrade flow to the left vertebral artery (LVA) is often achieved by transposition or bypass to the left subclavian artery during zone 2 thoracic endovascular aortic repair. An anomalous LVA (aLVA) originating directly from the aortic arch is a common arch variant with a reported incidence of 4% to 6%. In addition, 6% to 10% of vertebral arteries terminate in a posterior inferior cerebellar artery, increasing the risk of stroke if not revascularized.

Renal Artery Aneurysms in the Inpatient Setting.

Background: The risk of rupture of renal artery aneurysms (RAAs) remains undefined. A recent paper from the Vascular Low-Frequency Disease Consortium (VLFDC) identified only 3 ruptures in 760 patients. However, over 80% of patients in the VLFDC study were treated at large academic centers, which may not reflect the pattern of care of RAAs nationwide.

Baroreflex activation therapy with the Barostim™ device in patients with heart failure with reduced ejection fraction: a patient level meta-analysis of randomized controlled trials.

Aims: Heart failure with reduced ejection fraction (HFrEF) remains associated with high morbidity and mortality, poor quality of life (QoL) and significant exercise limitation. Sympatho-vagal imbalance has been shown to predict adverse prognosis and symptoms in HFrEF, yet it has not been specifically targeted by any guideline-recommended device therapy to date. Barostim™, which directly addresses this imbalance, is the first Food and Drug Administration approved neuromodulation technology for HFrEF.

Comparative early results of in situ fenestrated endovascular aortic repair and other emergent complex endovascular aortic repair techniques for ruptured suprarenal and thoracoabdominal aortic aneurysms at a regional aortic center.

Introduction: Emergent endovascular repair of suprarenal (SRAAAs) and thoracoabdominal aortic aneurysms (TAAAs) poses a significant challenge due to the need for branch vessel incorporation, time constraints, and lack of dedicated devices. Techniques to incorporate branch vessels have included parallel grafting, physician-modified endografts, double-barrel/reversed iliac branch device, and in situ fenestration (ISF). This study describes a single-center experience and the associated outcomes when using these techniques for ruptured SRAAAs and TAAAs.

Impact of high-risk features and timing of repair for acute type B aortic dissections.

Objective: The new Society for Vascular Surgery/Society for Thoracic Surgery reporting standards for type B aortic dissection (TBAD) categorize clinical presentations of aortic dissection into uncomplicated, high-risk features (HRF), and complicated groups. Although it is accepted that complicated dissections require immediate repair, the optimal timing of repair for HRF has yet to be established. This study aims to identify the ideal timing of thoracic endovascular aortic repair (TEVAR) for HRF, as well as outcomes associated with specific HRF.
