Introduction: Management of patients with large aortic arch aneurysms who are considered high risk for frozen elephant trunk technique have been challenging, especially when they have a dilated ascending aorta (AA) that precludes total endovascular branched repair (arch BEVAR). A viable option in our armamentarium is wrapping of the AA (AW), and zone 0 Ishimaru TEVAR.
Methods: Retrospective analysis of our aortic database from 2013 to 2024 to select high-risk patients with aortic arch aneurysm that had an AW and TEVAR.
Article Synopsis
- Z0BTEVAR is a minimally invasive procedure for repairing aortic arch issues in high-risk patients, focusing on chronic aortic dissection (C-AD) versus non-aortic dissection (N-AD) cases.
- A study involving 213 patients found that N-AD patients had a higher rate of in-hospital complications, including mortality and stroke, compared to those with C-AD, highlighting the impact of disease type on outcomes.
- The findings suggest that while Z0BTEVAR offers viable outcomes, careful patient selection and techniques to reduce stroke risks are crucial for improving post-operative results.
Article Synopsis
- * Data was collected from four European aortic centers between 2019 and 2023, focusing on patients with either ruptured or symptomatic aneurysms, looking at access complications, spinal cord issues, and mortality over a 30-day period, along with long-term outcomes like survival and need for interventions.
- * Findings showed a 9% complication rate from access, with a 7% mortality rate within 30 days;
Objective: Abdominal aortic aneurysm (AAA) shrinkage is considered a marker for success following endovascular aortic repair (EVAR). Although maximum diameter is widely used to assess sac behavior, research indicates that changes in AAA morphology do not always affect the maximum diameter. The aim of this study was to investigate if automated AAA sac volume measurements after EVAR can add more nuanced information on sac behavior compared with maximum diameter evaluation alone.

- The EXPAND registry evaluates the safety and performance of the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis (VBX stent) for use in peripheral vessels, focusing on its effectiveness as a bridging stent during branched endovascular aortic repair (BEVAR).
- A three-year study involved 73 patients from 16 European sites, assessing the primary and secondary patency rates, among other factors, revealing a high success rate with 93.6% primary patency across treated target vessels.
- Results indicated that while the VBX stent showed excellent long-term outcomes (94% primary and 97% secondary patency), patency rates were lower in renal arteries compared to other
Article Synopsis
- The study reviews a hybrid management approach for treating large thoracic aortic aneurysms (>80mm), combining endovascular techniques (TEVAR and FBEVAR) with open surgical repair without aortic cross-clamping.
- Researchers conducted a retrospective analysis of patients who underwent this treatment in two aortic centers from December 2017 to March 2024, focusing on patient outcomes such as survival, complications, and aneurysm size changes.
- Results showed a 100% survival rate within 30 days post-surgery and successful regression of the aneurysm sac in almost all patients, indicating that this hybrid method is both safe and effective for complex thoracic aneurysms.
Article Synopsis
- The study evaluates the use of a specialized aortic root endograft for treating acute type A aortic dissections (ATAAD) and proposes a new classification for aortic tears.
- With a high perioperative mortality rate of 12% to 20%, traditional surgical options are being compared to the Endobentall approach, which has only seen limited documentation in case reports.
- Out of 250 CT scans reviewed, 116 patients were analyzed, revealing that 63.7% were eligible for the Endobentall procedure, increasing to 73.3% under extended criteria, with most cases qualifying for the fenestrated version.
Objective: Despite the increasing number of fenestrated and branched endovascular aortic repair (F/B-EVAR) procedures, evidence on post-operative antiplatelet therapy is very limited. This study aimed to investigate the role of single antiplatelet therapy (SAPT) vs. double antiplatelet therapy (DAPT) after F/B-EVAR in 30 day and follow up outcomes.

Methods: An international, multicentre, retrospective observational study was undertaken including all consecutive patients who underwent endovascular arch repair with mechanical aortic valve crossing.
Results: From March 2020 to August 2023, 12 patients were included in the study (median age 55 years, interquartile range 45, 67 years; 58% male).
Branched endograft exclusion of chronic type A dissections resulting from a TEVAR complication is a minimally-invasive approach to consider in very fragile patients to mitigate the potential risks associated with conventional open surgical repair.

- The Delphi consensus aimed to clarify management practices for abdominal aortic aneurysms (AAAs) due to conflicting data in previous literature.
- A group of 44 experts anonymously discussed six key topics over three rounds, achieving a 100% response rate.
- Key findings included the agreement on minimum case volume for AAA repairs, the effectiveness of screening programs, lifelong surveillance after repair, and the consideration of screening for women smokers at 65, but no consensus on certain repair thresholds or thrombosis prevention was reached.

Objective: This study aimed to assess the impact of urgency on early and midterm outcomes of the Candy-Plug (CP) technique for distal false lumen (FL) occlusion in thoracic endovascular aortic repair for aortic dissection.
Methods: The CP registry was reviewed, and patients were categorized into elective and urgent/emergent groups for analysis. End points included technical success, clinical success, early (30-day) computed tomography angiography findings, early (30-day) mortality, adverse events, and aortic remodeling in patients with available computed tomography angiography follow-up and reintervention.
Article Synopsis
- This study reviews the outcomes of urgent repairs for juxtarenal/pararenal aneurysms using Cook's T-branch endografts across 23 European centers from 2013 to 2023.
- It analyzes data from 197 patients, mostly elderly, presenting with symptoms and large aneurysm sizes, indicating a need for urgent intervention.
- The results show a high technical success rate (92%), but complications included persistent spinal cord ischemia (8%) and a few cases of mortality, with rupture being a significant risk factor for technical failure.
Transcatheter stent implantation is a widely performed procedure for treating native coarctation of the aorta (CoA) in pediatric patients. However, data on mid- to long-term outcomes are limited. The aim of this study was to evaluate the mid-term safety and efficacy of transcatheter CoA stenting based on centrally adjudicated outcomes.

Despite the widespread use of VCDs, rare complications such as fragment emboli pose unique challenges, necessitating heightened clinical awareness. This case report presents a case of acute limb ischaemia caused by a VCD malfunction following an endovascular procedure.

- - TEVAR is a common treatment for complicated acute and high-risk uncomplicated Stanford Type-B aortic dissections, redirecting blood flow to seal the dissection tear, yet over 30% of patients still need more treatments due to ongoing issues with the false lumen.
- - Researchers propose a new technique called slit fenestration pattern creation to lessen the forces needed to keep the dissection flap in place, which could help in reducing complications post-TEVAR.
- - The effectiveness of this technique has been shown through virtual experiments and benchtop testing using porcine aortas, indicating it can significantly lower the pressure required for proper aortic wall remodeling.
