What the literature leaves open

  • The gap in current research is the need for a comprehensive review of the current literature to guide treatment decisions. There is also a need to balance the relative advantages and limitations of open vs. endovascular approaches in each patient. The paper identifies the lack of direct, meaningful comparisons between open and endovascular repair as a significant gap in current research.

    Open Repair of Thoracoabdominal Aortic Aneurysms in the Endovascular Era: When and for Whom · 2026 · DOI

    Machine learning–derived serum carbon dioxide trajectories in predicting prognosis of patients with acute aortic dissection · 2026 · DOI

  • The case report is limited to a single patient. The use of intermittent fluoroscopic monitoring during needle advancement may have contributed to the complication.

    Abdominal aortic pseudoaneurysm as a complication of percutaneous vertebroplasty: A case report · 2026 · DOI

  • Management of the aortic arch is increasingly becoming patient-specific and zone-driven with different options including open, hybrid and fully endovascular strategies. Open hemi- or total arch replacement remains the standard for durability, especially in younger patients and those with heritable thoracic aortic disease.

    Contemporary Management of the Aortic Arch: A Narrative Review · 2026 · DOI

  • The use of methodology with clear standardized boundary conditions (as opposed to personalized Windkessel models) was a deliberate choice to isolate the geometric effects of stent placement, which is the central focus of this pilot work. While this methodological approach serves the immediate study goal, the broader clinical validation of the immediate framework remains a necessary future step.

    A patient-specific CTA-CFD framework deciphers hemodynamic heterogeneity after fenestrated TEVAR: a pilot study · 2026 · DOI

  • Bleeding remains one of the most serious complications of the operation. The existing methods do not achieve 100% prevention of bleeding, thrombosis, and fistula formation.

    Method of implantation of an aortic conduit for aortic aneurysm · 2026 · DOI

  • The rarity of extensive Stanford Type A aortic dissection with near pan-aortic involvement. The atypical presentation of AD as sudden cardiac arrest without preceding symptoms.
