Table 2. Outcome parameters of the three groups.

Localization	extracranial	intracranial	extracranial
Systemic thrombolysis	yes	yes	no
Recanalization rate	30.8	30.0	8.6
Time to recanalization, days	3.5 (9.8)	1.5 (5.0)	5.5 (3.8)
mRS at 3 months	3.5±1.7	4.0±2.0	2.5±1.9
mRS ≤2 overall	25.0	20.0	52.2
mRS ≤2 with recanalization	31.2	50.0	44.4
mRS ≤2 without recanalization	22.2	7.1	53.1

Data are given as percentage, except mRS at 3 months, which is given as mean ± standard deviation, and time to recanalization, which is given as median (interquartile range). Presence of recanalization was judged based on the first control ultrasound, which was performed at a median 3.5 days after stroke. mRS, modified Rankin Scale.
