The annual conference of the Society of Vascular Surgeons (SVS) wrapped up over the weekend. After four days of networking, research presentations, and sharing insights, the VAM25 (Vascular Annual Meeting) conference concluded. 

We previewed VAM25, back in May, and today we have a rundown of some of the exciting research presented at the conference, related to aortic disease. The following posters were featured in the conference’s poster competition.

Comparing Neurological Complications Between Endovascular and Open Surgical Repair of Descending Thoracic Aortic Aneurysms

  • Description: Descending thoracic aortic aneurysm requires surgical intervention. While endovascular repair is minimally invasive (a stent graft is placed over the affected aorta), open repair is more invasive and replaces the aneurysm with a graft. The study compared neurological morbidity between the two approaches.
  • Result: Although the endovascular group had lower risk of mortality, they are at a higher risk of experiencing neurological adverse outcomes.

Real-World Outcomes of Open Surgical Repair vs Endovascular Aortic Repair in Ruptured Abdominal Aortic Aneurysms: Does Neck Anatomy Make a Difference?

  • Description: The study aimed to compare endovascular aortic repair (EVAR) and open surgical repair (OSR) in patients with rAAA using a recent national database, considering favorable neck (FN) vs hostile neck (HN) anatomy.
  • Result: EVAR was associated with reduced postoperative mortality and complication compared to OSR regardless of neck anatomy. However, EVAR maintained one-year survival superiority over OSR only in patients with FN anatomy. While EVAR-HN had similar one-year mortality to OSR, it remains the preferred option due to its better perioperative outcomes and lower 30-day mortality.

Volumetric Evaluation of Aortic Remodeling Following Type B Aortic Dissection Repair Using the PETTICOAT and STABILISE Techniques

  • Description: Researchers used volumetric analysis from sixteen patients to evaluate aortic remodeling between the PETTICOAT and STABILISE techniques.
  • Result: The studied measurements revealed that the STABILISE technique significantly outperformed the PETTICOAT technique in achieving positive aortic remodeling, as indicated by an increase in true lumen and a decrease in false lumen across all treated aortic zones.

Textbook Outcomes Correlate with Risk-adjusted 1-year Mortality for Branched/Fenestrated Aortic Repair in the United States Aortic Research Consortium

  • Description: The study evaluated the association of textbook outcomes with one-year mortality and assessed risk for failure to achieve textbook outcomes in patients treated with branched/fenestrated endovascular aortic repair (BFEVAR) in the United States Aortic Research Consortium (US-ARC).
  • Result: Failure to achieve a textbook outcome is significantly associated with one-year risk-adjusted mortality. Since most deaths occur outside the perioperative period, non-textbook-outcome patients merit closer monitoring after discharge.

Mid-term Outcomes After Urgent and Emergent In-Situ Laser Fenestrated Endovascular Aortic Repair of Thoracoabdominal and Complex Abdominal Aortic Aneurysms

  • Description: The study aimed to present mid-term outcomes of patients treated with laser in-situ fenestrated endovascular aortic repair for ruptured or symptomatic complex abdominal and thoracoabdominal aortic aneurysms.
  • Result: Laser in-situ fenestrated endovascular aortic repair is a feasible treatment option for patients presenting with ruptured or symptomatic complex abdominal and thoracoabdominal aortic aneurysms.

Long-Term Trends in Quality of Life in Patients Who Undergo Branched Endovascular Repair of Pararenal and Extent IV Thoracoabdominal Aortic Aneurysms

Description: The study’s objective was to analyze patient long-term quality-of-life trends in the TAMBE pivotal clinical trial.
Result: Patients who undergo TAMBE exhibited a gradual decline in health-related quality-of-life over the long term.
