Echo Catheter Use in Neuroendovascular Procedures Shows High Success Rate

Background Advanced neuroendovascular procedures require trackable and supportive guide catheters, which facilitate safe device delivery. The Echo intracranial base catheter was engineered as a large lumen (0.100” ID), low profile (8F closure) access catheter maximizing trackability, kink resistance, and lumen patency for efficient delivery of aspiration catheter during thrombectomy. This case series evaluates its performance as a guide catheter in various neurointerventional procedures. Methods Consecutive cases using the Echo access catheter were identified from a prospectively maintained patient database at a comprehensive stroke center between April and July 2025. Demographic, clinical, procedural, and angiographic characteristics were collected. Outcomes of interest included procedural success and peri‐procedural complications, including flow‐limiting vasospasm, vessel dissection, and thrombus formation. Results The Echo access catheter was used in a total of eleven cases including six thrombectomies, two venous sinus stents, one intracranial stent, one intracranial angioplasty and one aneurysm flow diversion. Average patient age was 61 years old, 6 (54.5%) were female and all had femoral access. The Echo catheter tip was placed in the petrous segment of ICAin three cases (27.2%), the lacerum segment in three cases (27.2%), the cervical segment in two cases (18.1%), the cavernous segment in one case (9.1%), the vertical petrous segment in one case (9.1%), and the transverse sinus in one case (9.1%). Intracranial stenting and flow diversion were completed with use of a distal access catheter and intracranial angioplasty was successfully performed with the Echo access catheter alone. The Echo access catheter was able to easily navigate to the transverse venous sinus over a ledge‐reducing delivery microcatheter and deliver devices for venous sinus stenting and angioplasty. There was a 100% procedural success rate. No significant catheter‐related complications were observed. Conclusions This series highlights the Echo access catheter's safe and effective use in a diverse representation of neuroendovascular procedures.
