Summary
A novel technique successfully treated a large cavernous aneurysm using a double-layered LVIS Blue stent. This innovative approach prevented stent retraction, offering a new solution for complex vascular cases.
Area of Science:
- Neurosurgery
- Interventional Neuroradiology
- Vascular Surgery
Background:
- Large cavernous aneurysms pose significant treatment challenges.
- Flow diverters are increasingly used for complex intracranial aneurysms.
- Stent migration or retraction can complicate endovascular procedures.
Observation:
- A case of double-layered LVIS Blue (LB) stent construct retraction into a large cavernous aneurysm was encountered.
- The LB stent construct was employed as a flow diverter for this challenging aneurysm.
- Standard treatment protocols were insufficient for this specific complication.
Findings:
- A novel, multi-step solution was developed to manage the retracted LB stent construct.
- This involved balloon angioplasty and the placement of a balloon-mounted cardiac stent through the LB construct's sidewall.
- A Pipeline Flex stent was ultimately deployed within the newly formed conduit.
Implications:
- This technique offers a viable salvage strategy for stent retraction during aneurysm treatment.
- It demonstrates the adaptability of endovascular techniques for complex neurovascular pathologies.
- Successful management of this complication may improve patient outcomes in similar challenging cases.
