Transcranial pulsed ultrasound with alteplase intravenous thrombolysis for vascular recanalisation in acute ischemic stroke

Abstract

The objective of study was to investigate the effect of transcranial pulsed ultrasound combined with alteplase on treatment of vascular recanalisation in acute ischemic stroke patients. Eighty-two patients were randomly divided equally into two groups. Group A was treated with transcranial pulsed ultrasound combined with alteplase intravenous thrombolysis. Group B received alteplase intravenous thrombolytic treatment. At 2 and 24 hours after treatment, National Institutes of Health Stroke Scale (NIHSS) score of group A was lower than that of group B (both p<0.001), and vascular recanalisation rate of patients in group A was higher than that of group B (p=0.004, and 0.002 respectively). At 90 days after treatment, rate of favourable prognosis [(modified rankin scale (mRS) ≤2 points)] of group A was higher than that of group B (p=0.001). Transcranial pulsed ultrasound combined with alteplase intravenous thrombolytic treatment can improve vascular recanalization rate and prognosis.
