Study Arms:
- Single-IVT strategy (SIS) cohort (Type: None): The SIS cohort included patients with MeVO strokes who received a single conventional alteplase IVT (IVT-1).
- Dual-IVT strategy (DIS) cohort (Type: None): The DIS cohort included patients with alteplase-treated MeVO strokes for whom a repeat MRI (MRI-2) was planned 1-2h after alteplase IVT (IVT-1) to discuss a possible complementary IVT with tenecteplase (TNK-IVT-2).~Patients could be in the following situations: already recanalized at 1-2h post-alteplase IVT-1, persistent occlusion treated with TNK-IVT-2 or persistent occlusion but additional IVT contraindicated according to the study protocol.

Based on this trial design, predict the completion outcome and termination type (if applicable).
