IVT pre-MT improves stroke recanalization success post-4.5 hours.
Determining whether direct mechanical thrombectomy (MT) is non-inferior to combined intravenous thrombolysis (IVT) and MT in an extended time window is crucial for optimizing acute stroke treatment. Direct MT did not demonstrate non-inferiority to IVT + MT beyond 4.5 hours, with lower successful recanalization rates in the direct MT group (adjOR 0.38). Findings suggest that IVT prior to MT might improve recanalization success in extended windows. Limitations include potential biases inherent to emulated trial designs. IVT before MT enhances recanalization success in the extended treatment window.
