Transcranial Doppler Evaluation After Endovascular Thrombectomy for Acute Ischemic Stroke (PRECISE-TCD) (NCT07013396)
A Prospective Evaluation of Clinical Outcomes in Acute Ischemic Stroke After Endovascular Treatment Using Transcranial Doppler (PRECISE-TCD)
🩺 Plain-English Summary (8th-Grade Level)
Endovascular thrombectomy (EVT) improves outcomes in acute ischemic stroke caused by large vessel occlusion. Despite successful recanalization, early neurological deterioration (END) remains frequent and is associated with poor outcomes. Transcranial Doppler (TCD) provides noninvasive, real-time assessment of cerebral blood flow velocities and may identify hemodynamic patterns associated with deterioration after EVT. PRECISE-TCD is a prospective, single-center observational study enrolling 180-300 patients undergoing EVT for anterior circulation large vessel occlusion at a tertiary academic medical center. Serial TCD examinations are performed immediately after EVT, daily for 72 hours, and as close as possible to early neurological deterioration events or clinically indicated head CT within 72 hours. The primary outcome is the association between TCD-derived hemodynamic parameters and END within 72 hours. Secondary outcomes include NIHSS at 24 hours and discharge, discharge disposition, and modified Rankin Scale at 90 days.
