Insights
Securely placing coils during arterial treatments at branch points is crucial. The VBX balloon-expandable stent graft offers a novel solution for challenging anatomies, improving patient outcomes.
Area of Science:
- Interventional Radiology
- Vascular Surgery
- Biomedical Engineering
Background:
- Stable coil placement is critical for treating arterial pathologies at vessel branch points.
- Coil migration (kick and escape) poses a risk to distal organs, especially with dense coil packing.
- Traditional stent grafts often struggle with varying vessel calibers, complicating secure coil coverage.
Abstract:
Stable coil placement is an imperative when treating arterial pathology at branch points. Coil kick and escape threaten distal organs, particularly as the pack tightens. Before the development of the VBX balloon-expandable stent graft (W.L. Gore, Flagstaff, AZ), vessel caliber change often precluded straightforward stent graft coverage with a single device to secure coils in place. We describe 3 cases using this unique feature of the Gore VBX device to accommodate challenging anatomy. All 3 patients recovered well.
