TCD = Transcranial doppler, MCA = Middle cerebral artery, PSV = Peak systolic velocity, EDV = End diastolic velocity, MFV = Mean systolic velocity, PI = Pulsatility index, RI = Resistance index, Hem Exp⁺ = Those with hematoma expansion, Hem Exp = Those without hematoma expansion. Significant P value: < 0.05
