BACKGROUND AND PURPOSE: Expanding mechanical thrombectomy (MT) capacity through
new thrombectomy-capable stroke centers (TSC) may increase MT utilization and
reduce treatment delays. We evaluated the impact of a newly opened TSC on MT
volume, delays, and clinical outcomes in France.
MATERIALS AND METHODS: We retrospectively analyzed data from two prospective
stroke databases (Bordeaux and Bayonne). We included patients presenting to
Bayonne with ischemic stroke who were transferred to Bordeaux for MT
(Drip-and-Ship, DS) before TSC opening, and patients presenting to and treated
at Bayonne after on-site MT availability (mothership, MS), from March 2015 to
February 2023. We compared MT volume, treatment delays, procedural outcomes,
safety, and 90-day functional outcomes between the two groups.
RESULTS: Among 272 patients, 82 (30.1%) were treated under DS (before March
2019) and 190 (69.9%) under MS. Annual MT volume tripled from ∼ 20 to 60 in the
first year after TSC opening. Median onset-to-puncture time was significantly
shorter in MS (198 min, IQR 158-248) versus DS (335 min, IQR 280-375;
