REtrieving thrombi and Separated Coils/catheters Unexpectedly detached during Endovascular therapy: RESCUE – the use of thrombectomy devices for rescue therapy in interventional neuroradiology

Abstract

Purpose

Intraprocedural complications during intracranial embolisation include thromboembolic vessel occlusion, catheter tip detachment and coil migration. Stentrievers and aspiration catheters are valuable devices for the management of these complications. We present our experience with the use of these devices. We describe the devices and techniques used, case details and clinical outcomes. Currently there is no standardised approach for the management of the above intraprocedural complications.

Methods

We performed a retrospective review of our interventional neuroradiology database of patients who underwent endovascular treatment in our institution from January 2012 to January 2019 and identified embolisation procedures during which either stentrievers or aspiration catheters were utilised.

Results

We present a case series of 24 cases in which these devices were utilised as rescue devices over a period of 7 years. We provide three illustrative cases.

Conclusion

Stentrievers and aspiration catheters can be used safely and effectively as adjunctive or rescue devices during embolisation procedures.
