Summary
The Funnel technique offers a safe and effective solution for endovascular aneurysm repair in patients with wide aortic necks. This hybrid approach demonstrates excellent midterm outcomes, making it a valuable option for complex cases.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Aneurysm Repair
Background:
- The Funnel technique is a hybrid endograft assembly for thoracic and abdominal aortas.
- It is beneficial for frail patients unable to achieve sufficient oversizing for infrarenal aortic necks > 34 mm.
Purpose of the Study:
- To evaluate the advantages and disadvantages of the Funnel endovascular aneurysm repair (EVAR) technique.
- To assess the efficacy of using a 60 mm length thoracic endograft in this procedure.
Main Methods:
- Retrospective study of 22 frail patients with high comorbidities undergoing Funnel-EVAR.
- Use of a 60 mm Lifetech Ankura thoracic endograft in urgent and elective cases.
- Primary endpoints: technical success, early mortality/morbidity. Secondary endpoints: late outcomes like endoleak, migration, sac shrinkage.
Main Results:
- 100% technical success with no early mortality or morbidity.
- Mean follow-up of 32.8 months showed no endoleak, migration, or neck/sac enlargement.
- Three late deaths occurred, but none were aneurysm-related.
Conclusions:
- Funnel-EVAR is effective and safe for patients with wide infrarenal aortic necks (> 34 mm) based on midterm outcomes.
- This technique should be considered by vascular surgeons for managing patients with wide aortic necks.

Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.

01:18Effects of EDTA on End-Point Detection Methods
270
Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
