Case in brief
This report describes a retrospective series of 24 embolisation procedures in which stentrievers or aspiration catheters were used as rescue devices for intraprocedural complications. The complications included thromboembolic vessel occlusion, catheter-tip detachment and coil migration. The authors detail the devices and techniques used and report clinical outcomes, with three cases presented as illustrations. They conclude that these devices can be used safely and effectively as adjunctive or rescue tools during embolisation procedures.
What made this case unusual
The report focuses on using thrombectomy devices to address several distinct complications of intracranial embolisation, including detached catheter tips and migrated coils, rather than only thromboembolic occlusion.
Diagnostic / clinical pearl
Stentrievers and aspiration catheters may serve as rescue tools for thromboembolic occlusion, catheter-tip detachment or coil migration during embolisation.
Why it matters
The authors note that no standardised approach exists for managing these intraprocedural complications.
