Echo intracranial base catheter use in neuroendovascular procedures: Institutional experience.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It carries an expression of concern. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BackgroundAdvanced neuroendovascular procedures require trackable and supportive guide catheters, which facilitate safe device delivery. Echo intracranial base catheter was engineered as a large lumen (0.100″ ID) access catheter that is super trackable, supportive, and kink resistance, all while fitting within the puncture of a typical 8F sheath when its used with the thin-walled, Dash short sheath (9F). This case series evaluates its performance as a guide catheter in various neurointerventional procedures.MethodsConsecutive cases using an 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 periprocedural complications, including flow-limiting vasospasm, vessel dissection, and thrombus formation.ResultsEcho 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. Echo catheter tip was placed in the petrous segment of ICA in 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 an Echo access catheter alone. 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.ConclusionsThis series highlights Echo access catheter's safe and effective use in a diverse representation of neuroendovascular procedures.
