This work investigates the spherically symmetric thin-shell wormhole solutions in four-dimensional Einstein-Gauss-Bonnet theory and explores their stabilities under radial, linear perturbations. These are typically traversable characterized by a throat accordance with Israel's junction conditions. In asymptotically flat AdS spacetimes negative Gauss-Bonnet coupling constant, stable neutral wormholes encountered when magnitude of constant becomes significant. The throats such sustained ordinary matter possess finite radii. dS spacetimes, no featuring is observed. On other hand, for positive can be established exclusively supported exotic matter. Moreover, charged comprised found universally flat, AdS, spacetimes. Unlike counterparts, radii arbitrarily small. However, as charge more significant, only remain
