Summary
Fiber Optic RealShape (FORS) guidance shows promise for complex endovascular aortic repair (EVAR), achieving high technical success rates. This advanced technique reduces procedural times and radiation exposure for patients undergoing EVAR.
Area of Science:
- Vascular Surgery
- Medical Device Technology
- Interventional Radiology
Background:
- Complex endovascular aortic repair (EVAR) procedures, including fenestrated and branched techniques, require precise navigation.
- Minimizing procedural time and radiation exposure are critical goals in EVAR to improve patient outcomes and reduce healthcare costs.
Purpose of the Study:
- To evaluate the technical success of Fiber Optic RealShape (FORS) endovascular guidance in complex EVAR.
- To assess the impact of FORS guidance on procedural time and radiation usage compared to conventional methods.
Main Methods:
- A single-center, prospective study of fenestrated and branched EVARs from 2017-2022.
- Retrospective matching of 21 FORS-guided procedures to 61 non-FORS-guided procedures.
- Logistic regression for technical success predictors; Wilcoxon rank sum test for time and radiation comparisons.
Main Results:
- Technical success was achieved in 85% of FORS-guided cannulations (81/95).
- FORS guidance was associated with significantly shorter procedural and fluoroscopy times.
- FORS use led to a significant reduction in radiation dose (lower dose area product and air kerma).
Conclusions:
- Initial experience with FORS guidance in complex EVAR demonstrates promising technical success.
- FORS technology offers potential reductions in procedural duration and radiation exposure.
- Further evaluation of the learning curve and long-term outcomes with FORS is warranted.
