We prove a result about sequences of Riemannian metrics on a closed aspherical 3-manifold such that the sectional curvature is locally controlled
and the thick part asymptoticaly converges to a hyperbolic 3-manifold. Then Perelman's long term Ricci flow with surgeries allows to apply this result to get a proof of the geometrization conjecture for aspherical 3-manifolds.
