  "abstract": "Introduction/Purpose Vascular access strategy is a key determinant of procedural efficiency and device delivery in contemporary neurointervention. Although transradial access has gained widespread acceptance because of its high feasibility and low access-site complication rates, technical limitations related to catheter support, trackability, and compatibility with large-bore systems remain important barriers in complex cerebrovascular anatomy. Newer access platforms have been developed to address these constraints and optimize radial workflows. The Zebra neurovascular access catheter is one such system designed for use in both radial and femoral neuroendovascular procedures. However, published real-world experience remains limited. We sought to describe our initial single-center experience with the Zebra catheter, with emphasis on feasibility, procedural effectiveness, and workflow performance in a predominantly radial-first practice.Materials and Methods We performed a retrospective, single-center case series of consecutive neuroendovascular procedures in which the Zebra catheter was used at a single institution. Cases were identified from an institutional procedural dataset. Extracted variables included demographics, indication, procedure type, access site, target vascular territory, catheter configuration, and procedural metrics, including puncture-to-cervical-access time, fluoroscopy duration, contrast volume, radiation dose, and total procedural time. The primary effectiveness endpoint was operator-recorded procedural success. Secondary endpoints included workflow metrics. Safety assessment was limited by the absence of standardized complication fields and longitudinal follow-up and was therefore restricted to identifying structured evidence of overt access- or device-related failure. Outcomes were summarized descriptively.Results A total of 52 cases were included. Mean age was 66.1 years (SD 16.8), and 32 patients (61.5%) were women. The cohort included 25 AIS thrombectomy cases (48.1%), 24 aneurysm/embolization cases (46.2%), and 3 other procedures (5.8%). The Zebra catheter was used predominantly in a radial-first workflow, with radial access in 48 cases (92.3%), including 47 right radial and 1 left radial case; 4 procedures (7.7%) were performed via right femoral access as dual access was deemed necessary for treatment of the pathology. Operator-recorded procedural success was documented in 50 cases (96.2%). One case was deemed to have excessive tortuosity for catheter integrity and one case had proximal radial loop anatomy. Across the full cohort, median puncture-to-cervical-access time was 10.0 minutes, median fluoroscopy duration was 23.6 minutes, median contrast volume was 55 mL, median radiation dose was 607.3 mGy, and median total procedural time was 56.0 minutes. Workflow metrics varied by case type, for instance; median puncture-to-cervical-access time was 8.0 minutes for AIS thrombectomy cases and 15.5 minutes for aneurysm/embolization cases; median total procedural time was 35.0 and 78.0 minutes, respectively.Conclusions In this initial single-center experience, the Zebra neurovascular access catheter demonstrated high procedural success and favorable workflow performance across a heterogeneous neuroendovascular cohort and was used predominantly through radial access within a radial-first practice. These findings support the Zebra catheter as a feasible, versatile, and procedurally effective access platform for both acute thrombectomy and elective aneurysm/embolization procedures. Larger multicenter studies with standardized safety outcomes and comparative analyses are warranted to further define its clinical role and relative advantages among contemporary access systems.Disclosures P.
