Physicians' Preference for Carotid Revascularization Impacts Postoperative Stroke and Death Outcomes.

Background: TransCarotid artery revascularization (TCAR) is a safe minimally invasive option for patients with carotid artery stenosis who are not appropriate candidates for carotid endarterectomy (CEA). Many physicians have not yet adopted this technique in the management of carotid artery stenosis. The aim of this study is to explore overall outcomes of carotid revascularization based on physicians' practices in the Vascular Quality Initiative (VQI).

An International, Expert-Based Delphi Consensus Document on Controversial Issues about TransCarotid Artery Revascularization (TCAR).

Background: Transcarotid artery revascularization (TCAR) has emerged as an alternative therapeutic modality to carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TFCAS) for the management of patients with carotid artery stenosis. However, certain issues regarding the indications and contraindications of TCAR remain unanswered or unresolved. The aim of this international, expert-based Delphi consensus document was to attempt to provide some guidance on these topics.

Seven years of the transcarotid artery revascularization surveillance project, comparison to transfemoral stenting and endarterectomy.

Objective: This study utilizes the latest data from the Vascular Quality Initiative (VQI), which now encompasses over 50,000 transcarotid artery revascularization (TCAR) procedures, to offer a sizeable dataset for comparing the effectiveness and safety of TCAR, transfemoral carotid artery stenting (tfCAS), and carotid endarterectomy (CEA). Given this substantial dataset, we are now able to compare outcomes overall and stratified by symptom status across revascularization techniques.

Methods: Utilizing VQI data from September 2016 to August 2023, we conducted a risk-adjusted analysis by applying inverse probability of treatment weighting to compare in-hospital outcomes between TCAR vs tfCAS, CEA vs tfCAS, and TCAR vs CEA.

Predictors of prolonged length of stay after elective carotid revascularization.

Objective: Postoperative day-one discharge is used as a quality-of-care indicator after carotid revascularization. This study identifies predictors of prolonged length of stay (pLOS), defined as a postprocedural LOS of >1 day, after elective carotid revascularization.

Methods: Patients undergoing carotid endarterectomy (CEA), transcarotid artery revascularization (TCAR), and transfemoral carotid artery stenting (TFCAS) in the Vascular Quality Initiative between 2016 and 2022 were included in this analysis.

Secondary interventions following open vs endovascular revascularization for chronic limb threatening ischemia in the BEST-CLI trial.

Objectives: Patients undergoing revascularization for chronic limb-threatening ischemia experience a high burden of target limb reinterventions. We analyzed data from the Best Endovascular versus Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) randomized trial comparing initial open bypass (OPEN) and endovascular (ENDO) treatment strategies, with a focus on reintervention-related study endpoints.

Methods: In a planned secondary analysis, we examined the rates of major reintervention, any reintervention, and the composite of any reintervention, amputation, or death by intention-to-treat assignment in both trial cohorts (cohort 1 with suitable single-segment great saphenous vein [SSGSV], n = 1434; cohort 2 lacking suitable SSGSV, n = 396).

Cytomegalovirus Infection Facilitates the Costimulation of CD57+CD28- CD8 T Cells in HIV Infection and Atherosclerosis via the CD2-LFA-3 Axis.

CD8 T cells are emerging as important mediators in atherosclerosis and cardiovascular disease (CVD). Immune activation may play a particular role in people with HIV (PWH) who are at an increased risk of CVD, even after controlling for known CVD risk factors. Latent CMV infection is associated with increased CVD risk for both PWH and people without HIV, and human CMV-specific CD4 and CD8 T cells are enriched for an immunosenescent phenotype.

Direct oral anticoagulants over warfarin at discharge associated with improved survival and patency in infra-geniculate bypasses with prosthetic conduits.

Objective: There is no consensus on the optimal anticoagulant regimen following lower extremity bypass. Historically, warfarin has been utilized for prosthetic or compromised vein bypasses. Direct-acting oral anticoagulants (DOACs) are increasingly replacing warfarin in this context, but their efficacy in bypass preservation has not been well-studied.

Female and male patients have similar outcomes after transcarotid artery revascularization in prospective trials.

Objective: Sex disparities in outcomes after carotid revascularization have long been a concern, with several studies demonstrating increased postoperative death and stroke for female patients after either carotid endarterectomy or transfemoral stenting. Adverse events after transfemoral stenting are higher in female patients, particularly in symptomatic cases. Our objective was to investigate outcomes after transcarotid artery revascularization (TCAR) stratified by patient sex hypothesizing that the results would be similar between males and females.

Chocolate Touch Versus Lutonix Drug-Coated Balloon for Femoropopliteal Lesions in Diabetes: The Chocolate Touch Study.

Background: The randomized Chocolate Touch Study demonstrated that in patients undergoing treatment of femoropopliteal artery lesions, the Chocolate Touch drug-coated balloon (DCB) was safe and had superior efficacy at 12 months compared with the Lutonix DCB. We report the prespecified diabetes subanalysis comparing outcomes among patients with and without diabetes mellitus (DM).

Methods: Patients with claudication or ischemic rest pain (Rutherford class 2-4) were randomized to Chocolate Touch or Lutonix DCB.

Regional variation in patient selection, practice patterns, and outcomes based on techniques for carotid artery revascularization in the Vascular Quality Initiative.

Objective: Significant regional variation is known with multiple surgical procedures. This study describes regional variation in carotid revascularization within the Vascular Quality Initiative (VQI).

Methods: Data from the VQI carotid endarterectomy (CEA) and carotid artery stenting (CAS) databases from 2016 to 2021 were used.

Anatomic Utility of Single Branched Thoracic Endograft During Thoracic Endovascular Aortic Repair.

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.

Risk of Stroke, Death, and Myocardial Infarction Following Transcarotid Artery Revascularization vs Carotid Endarterectomy in Patients With Standard Surgical Risk.

Importance: Carotid artery stenting has been limited to use in patients with high surgical risk; outcomes in patients with standard surgical risk are not well known.

Objective: To compare stroke, death, and myocardial infarction outcomes following transcarotid artery revascularization vs carotid endarterectomy in patients with standard surgical risk.

Design, Setting, And Participants: This retrospective propensity-matched cohort study was conducted from August 2016 to August 2019 with follow-up until August 31, 2020, using data from the multicenter Vascular Quality Initiative Carotid Artery Stent and Carotid Endarterectomy registries.

Outcome after revascularization with paclitaxel-coated devices in patients with chronic limb-threatening ischemia.

Objective: Data regarding the safety and efficacy of paclitaxel (PTX)-coated peripheral arterial devices for femoropopliteal artery (FPA) atherosclerotic disease is derived from studies that mainly evaluated patients with claudication. Outcomes of PTX treatment for patients with chronic limb-threatening ischemia (CLTI) is incompletely defined. This study compares outcome in patients with CLTI treated with and without PTX.

TransCarotid Artery Revascularization Can Be Safely Performed in Patients Undergoing Dialysis.

Background: TransCarotid Artery Revascularization (TCAR) has been effectively performed to prevent stroke in patients with carotid artery stenosis (CS). Prior studies established that TCAR can be safely performed in high-risk patients such as octogenarians, patients with prior carotid endarterectomy (CEA), contralateral occlusion, and heavily calcified lesions. Hemodialysis patients are at an increased risk of exhibiting cardiovascular complications.

Cortical Thinning in High-Grade Asymptomatic Carotid Stenosis.

Background And Purpose: High-grade carotid artery stenosis may alter hemodynamics in the ipsilateral hemisphere, but consequences of this effect are poorly understood. Cortical thinning is associated with cognitive impairment in dementia, head trauma, demyelination, and stroke. We hypothesized that hemodynamic impairment, as represented by a relative time-to-peak (TTP) delay on MRI in the hemisphere ipsilateral to the stenosis, would be associated with relative cortical thinning in that hemisphere.

Physiologic risk factors increase risk of myocardial infarction with transcarotid artery revascularization in prospective trials.

Objective: Patients can be considered at high risk for carotid endarterectomy (CEA) because of either anatomic or physiologic factors and will often undergo transcarotid artery revascularization (TCAR). Patients with physiologic criteria will be considered to have a higher overall surgical risk because of more significant comorbidities. Our aim was to study the incidence of stroke, myocardial infarction (MI), death, and combined end points for patients who had undergone TCAR stratified by the risk factors (anatomic vs physiologic).

Use of direct-acting oral anticoagulants associated with improved survival and bypass graft patency compared with warfarin after infrageniculate bypass.

Objective: No consensus has yet been reached regarding the optimal antiplatelet and anticoagulant regimen for patients after lower extremity bypass. Usually, patients who have undergone below-the-knee bypass will begin oral anticoagulation therapy. Historically, the bypass has been with prosthetic conduits and the anticoagulation therapy has been warfarin.

Management and Outcome of Non-Aneurysmal Primary Aortic Infection.

Introduction: Aortic infection without prior intervention or aneurysm is exceedingly rare. We report the presentation, diagnosis, management, and outcome of patients with this unusual entity.

Methods: Retrospective chart and imaging review of patients with primary aortic infection.

Impact of interfacility transfer of ruptured abdominal aortic aneurysm patients.

Objective: The interfacility transfer (IT) of patients with a ruptured abdominal aortic aneurysm (rAAA) occurs not infrequently to allow for a higher level of care. In the present study, we evaluated, using a contemporary administrative database, the effects of IT on mortality after rAAA repair.

Methods: The Healthcare Cost and Utilization Project Database for New York (2016) and New Jersey, Maryland, and Florida (2016-2017) was queried using the International Classification of Diseases, 10th edition, to identify patients who had undergone open or endovascular repair of AAAs.

In-situ bypass is associated with superior infection-free survival compared with extra-anatomic bypass for the management of secondary aortic graft infections without enteric involvement.

Objective: The optimal revascularization modality following complete resection of aortic graft infection (AGI) without enteric involvement remains unclear. The purpose of this investigation is to determine the revascularization approach associated with the lowest morbidity and mortality using real-world data in patients undergoing complete excision of AGI.

Methods: A retrospective, multi-institutional study of AGI from 2002 to 2014 was performed using a standardized database.

One-year outcomes after transcarotid artery revascularization (TCAR) in the ROADSTER 2 trial.

Objectives: Transcarotid artery revascularization (TCAR) is a carotid stenting technique that utilizes reversal of cerebral arterial flow to confer cerebral protection. Although carotid endarterectomy (CEA) remains the standard for treatment of symptomatic and asymptomatic carotid stenosis, the search for the optimal minimally invasive option for the high-risk surgical patient continues. The goal of the current study is to evaluate the 1-year safety and efficacy of TCAR in a prospective clinical trial.

Transcarotid revascularization outcomes do not differ by patient age or sex.

Background: Transcarotid artery revascularization (TCAR) is a hybrid approach to carotid revascularization. Limited information is available on the differences in periprocedural complications and performance measures of TCAR for men compared with women and for older vs younger adults.

Methods: The patient, lesion, and physician characteristics were collected for all TCAR procedures performed by each physician worldwide in an international quality assurance database between March 3, 2009 and May 7, 2020.
