Abstract W P192: A Direct Telecommunication Between Doctors of a Comprehensive Stroke Center and Local Hospitals Significantly Shortened the Door-to-Puncture Time for Intraarterial Thrombectomy

Background: We evaluated whether a direct doctor-to-doctor telecommunication (D2D-Call) between a comprehensive stroke center and local hospitals was effective to rapidly start intraarterial thrombectomy (IAT) for acute ischemic stroke patients, who first visit local hospital. Methods: Clinical data of 92 consecutive patients (male:female, 63:29; mean age±standard deviation, 68.6±11.4 years), who underwent IAT for terminal internal carotid and/or middle cerebral artery occlusions, were analyzed. The patients were classified by arrival manners at Stroke Center; 1) Direct-Arrival at Center (n=59), 2) Arrival after D2D-Call (n=20), and 3) Arrival without D2D-call (Non-D2D-Call, n=13). The D2D-call system had three parts; 1) D2D-Call for transfer, 2) activation of IAT team before arrival, and 3) immediate start of IAT after arrival of a patient. Time intervals from arrival to IAT start (Arrival-to-IAT) and from symptom onset to recanalization (Onset-to-Recanalization) was compared between three groups. The ra...
