Background: This study aimed to evaluate the suitability of a coronary-branched ascending aortic endograft, paired with aortic valve (AV) prosthesis (Endo-Bentall), for the endovascular repair of ascending aortic aneurysms.
Methods: Preoperative ≤1 mm computed tomography angiographies of consecutive patients managed with Bentall procedure or ascending aortic replacement and AV reconstruction/replacement, in a single institution (from January 1, 2008, to December 31, 2023), were retrospectively analyzed. Dedicate software was used to assess (1) vascular access, (2) proximal landing zone, (3) coronary artery anatomy, and (4) distal landing.
Article Synopsis
- The study aimed to assess the effectiveness and safety of bridging covered stents (BCS) connected to inner branches of custom-made thoracoabdominal endografts during endovascular aortic repair procedures.
- Conducted between 2019-2022, it involved 69 patients, reporting a high technical success rate of 99%, but also noted a 23% complication rate and 9% perioperative mortality.
- Follow-up results showed varying rates of stent occlusion, with 6% for visceral and 14% for renal BCS, and identified misalignment of the target vessel ostium and the infrarenal aortic angle as significant factors influencing renal BCS
Article Synopsis
- The study discusses a technique for using a modified balloon-expandable covered stent to selectively occlude a distal entry tear in a patient with chronic type B aortic dissection and an expanding false lumen.
- A 63-year-old male patient showed progression in false lumen size, prompting the need for intervention since traditional endovascular repair wasn't an option.
- The technique involved off-centering the stent to create a funnel shape for effective occlusion, and post-procedure imaging confirmed the successful exclusion of the targeted areas with some residual type 2 endoleak.
Article Synopsis
- - Transfemoral access (TFA) is an effective alternative to upper extremity access (UEA) for branched endovascular aortic repair (bEVAR), but it poses risks of reduced blood flow in the lower limbs due to the large introducer sheaths used during the procedure.
- - A study involving 24 patients assessed lower limb blood flow during TFA-bEVAR by measuring ankle blood pressure and toe pulse oximetry before and after sheath insertions, revealing significant improvements in limb perfusion when downsizing the sheath from 10F to 14F.
- - The results showed a reduction in limb perfusion reduction (LPR) from 87.5% after the main body delivery system placement
Article Synopsis
- The study examines the preservation of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) and its related outcomes, particularly focusing on stent compression in patients undergoing fenestrated endovascular arch repair (f-Arch).
- It involves a retrospective analysis of 54 patients using single-fenestration devices and evaluates various anatomical and technical factors that may influence stent performance and clinical results.
- The findings indicate low morbidity with no reported strokes or ischemia, though 18% of cases experienced stent compression, linked to factors like proximity to bone structures and a higher tortuosity index.
