Federated Bayesian Surveillance of Mechanical Thrombectomy Adverse Events
The work treats population-scale adverse-event surveillance as a distinct belief layer of a surgical digital twin, evaluated with a federated Bayesian protocol under formal privacy guarantees: sites exchange only differentially private natural-parameter updates. Benchmarking uses the full FDA MAUDE cohort for thrombus-retrieval catheters — 8,617 reports, 6,491 classified into five complication classes across eight manufacturer sites.
