Impact of Open Surgical Descending Repair on Aortic Stiffness in an Ex Vivo Porcine Model.

Objective: Previous studies have strongly suggested that stent-graft deployment and acute arch angulation increase aortic stiffness, the impact of surgical interposition grafting remains unclear. We investigated the impact of open surgery on aortic stiffness and compared this with stent-graft induced aortic stiffening, utilising an ex vivo model.

Methods: Porcine thoracic aortas were connected to a mock circulatory loop.

Outcomes of Endovascular Repair Confined to the Ascending Thoracic Aorta: A Systematic Review and Meta-Analysis.

Objective: High risk, inoperable patients with ascending aortic disease are increasingly managed with thoracic endovascular aortic repair (TEVAR). The aim of this study was to assess the available literature on TEVAR confined to the ascending aorta (a-TEVAR), describing study and patient characteristics, procedural and stent graft details, and outcomes.

Data Sources: This was a systematic review and meta-analysis.

Retroperitoneal vs transperitoneal approach for nonruptured open conversion after endovascular aneurysm repair.

Objective: Several studies comparing the transperitoneal (TP) and retroperitoneal (RP) approach for abdominal aortic aneurysm (AAA) repair suggest that the RP approach may result in lower rates of perioperative mortality and morbidity. However, data comparing these approaches for open conversion are lacking. This study aims to evaluate the association between the type of approach and outcomes following open conversion after endovascular aneurysm repair (EVAR).

Factors associated with and outcomes of respiratory adverse events following thoracic endovascular aortic repair.

Objective: Respiratory adverse events (RAEs) after thoracic endovascular aortic repair (TEVAR) remain poorly characterized owing to the lack of comprehensive studies that identify individuals prone to these complications. This study aims to determine the incidence, factors associated with, and outcomes of RAEs after TEVAR.

Methods: We identified patients in the Vascular Quality Initiative undergoing TEVAR isolated to zones 0 to 5 from 2010 to 2023 for nontraumatic pathologies.

Outcomes of carotid revascularization stratified by procedure in patients with an estimated glomerular filtration rate of <30 and dialysis patients.

Objective: Renal failure is a predictor of adverse outcomes in carotid revascularization. There has been debate regarding the benefit of revascularization in patients with severe chronic kidney disease or on dialysis.

Methods: Patients in the Vascular Quality Initiative undergoing transcarotid artery revascularization (TCAR), transfemoral carotid artery stenting (tfCAS), or CEA between 2016 and 2023 with an estimated glomerular filtration rate (eGFR) of <30 mL/min/1.

Antegrade cerebral perfusion via the right subclavian artery during open distal arch or proximal descending aortic repair from left thoracotomy.

In the current endovascular era, open surgery through left posterolateral thoracotomy with moderate to deep hypothermic circulatory arrest remains an alternative for treating chronic distal arch or proximal descending aortic diseases, allowing cardiovascular surgeons to definitively repair the aorta in a single stage. When utilizing this approach, this report illustrates an alternative surgical technique for antegrade body perfusion during cooling, antegrade selective cerebral perfusion and rewarming, through a prosthetic graft on the right subclavian artery. This report shows the safety and feasibility of this technique during open distal arch and/or proximal descending aortic surgery through left posterolateral thoracotomy, after shifting the patient from a supine to the right lateral decubitus position.

National registry insights on genetic aortopathies and thoracic endovascular aortic interventions.

Objective: Thoracic endovascular aortic repair (TEVAR) in patients with genetic aortopathies (GA) is controversial, given concerns of durability. We describe characteristics and outcomes after TEVAR in patients with GA.

Methods: All patients undergoing TEVAR between 2010 and 2023 in the Vascular Quality Iniatitive were identified and categorized as having a GA or not.

Surgeon volume and outcomes following thoracic endovascular aortic repair for blunt thoracic aortic injury.

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 and 2023. Annual surgeon volumes were computed as the number of TEVARs (for any pathology) performed over a 1-year period preceding each procedure and were further categorized into quintiles.

Type III aortic arch angulation increases aortic stiffness: Analysis from an ex vivo porcine model.

Objective: The relationship among increased aortic arch angulation, aortic flow dynamics, and vessel wall stiffness remains unclear. This experimental ex vivo study investigated how increased aortic arch angulation affects aortic stiffness and stent-graft induced aortic stiffening, assessed by pulse wave velocity (PWV).

Methods: Porcine thoracic aortas were connected to a circulatory mock loop in a Type I and Type III aortic arch configuration.

Role of Preoperative Embolization in Surgical Management of Carotid Body Tumors: A Systematic Review and Meta-Analysis.

The objective of this study is to evaluate the effect of preoperative embolization on carotid body tumor resection. A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. PubMed, Scopus, and Web of Science were screened for studies published between 2010 and 2022.

Sex-related Outcomes After Thoracic Endovascular Repair for Intact Isolated Descending Thoracic Aortic Aneurysm: A Retrospective Cohort Study.

Objective: The aim of this study was to evaluate the association between sex and outcomes following thoracic endovascular aortic repair (TEVAR) for intact isolated descending thoracic aortic aneurysms (iiDTAA).

Background: Data regarding sex-related long-term outcomes after TEVAR for iiDTAA are limited and conflicting results regarding perioperative outcomes have been reported.

Methods: We included all TEVAR for iiDTAA between 2014 and 2019 in the Vascular Quality Initiative linked to Medicare claims, allowing reliable assessment of long-term outcome data.

Sex-Specific Morphometric Analysis of Ascending Aorta and Aortic Arch for Planning Thoracic Endovascular Aortic Repair: A Retrospective Cohort Study.

Objective: In many studies on aortic disease, women are underrepresented. The present study aims to assess sex-specific morphometric differences and gain more insight into endovascular treatment of the ascending aorta (AA) and arch.

Methods: Electrocardiogram-gated cardiac computed tomography scans of 116 consecutive patients who were evaluated for transcatheter aortic valve replacement were retrospectively reviewed.

Utilizing numerical simulations to prevent stent graft kinking during thoracic endovascular aortic repair.

Numerical simulations of thoracic endovascular aortic repair (TEVAR) may be implemented in the preoperative workflow if credible and reliable. We present the application of a TEVAR simulation methodology to an 82-year-old woman with a penetrating atherosclerotic ulcer in the left hemiarch, that underwent a left common carotid artery to left subclavian artery bypass and consequent TEVAR in zone 2. During the intervention, kinking of the distal thoracic stent graft occurred and the simulation was able to reproduce this event.

Acute venous problems: Integrating medical, surgical, and interventional treatments.

"Acute venous problems" refers to a group of disorders that affect the veins and result in sudden and severe symptoms. They can be classified based on the pathological triggering mechanisms, such as thrombosis and/or mechanical compression, and their consequences, including symptoms, signs, and complications. The management and therapeutic approach depend on the severity of the disease, the location, and the involvement of the vein segment.
