Mechanical Thrombectomy with Aspiration Catheter Advanced from the Level of Aortic Arch for Unfavorable Vascular Anatomy

Abstract

Objective: Unfavorable vascular anatomy makes thrombectomy challenging. We report a technique to overcome the challenge by using the Neuro EBU catheter and an aspiration catheter.

Case Presentations: The 8F Neuro EBU catheter with an S-shaped stiff tip is placed at the origin (at the level of aortic arch) of the target vessel. Through this catheter, an aspiration catheter is advanced into the target vessel over a 0.035-inch guidewire. Thrombectomy with contact aspiration or a combined technique with a stent retriever is carried out.

Conclusion: The technique described here is simple and useful to access the target vessel and, therefore, to achieve quicker recanalization in thrombectomy complicated with challenging aortic arch or cervical arteries.
