Summary
This study modified a technique to treat false lumens after aortic repair. The novel approach successfully occluded false lumens in two patients, preventing further complications.
Area of Science:
- Vascular Surgery
- Endovascular Techniques
- Aortic Aneurysm Repair
Background:
- Central aortic repair can lead to patent, dilated false lumens (FLs).
- Managing these FLs is crucial to prevent complications.
- Existing techniques may have limitations in conforming to irregular lumens.
Observation:
- A modified candy-plug technique was employed using an AFX VERA suprarenal extension.
- Restricted purse-string sutures shaped the device into a candle-like plug.
- The plug was deployed into the FL to occlude retrograde blood flow proximally.
Findings:
- The modified technique was applied to two patients with patent, dilated FLs.
- Both patients demonstrated partial or complete FL thrombosis at 6 months post-procedure.
- The technique proved feasible for effective FL occlusion.
Implications:
- This modified candy-plug technique offers a potential solution for managing false lumens after aortic repair.
- It demonstrates feasibility and positive outcomes in a small patient cohort.
- Further research may explore its broader application in complex aortic pathologies.
