摘 要:This research aims to demonstrate a novel vortex ultrasound enabled endovascular thrombolysis method designed for treating cerebral venous sinus thrombosis(CVST).This is a topic of substantial importance since current treatment modalities for CVST still fail in as many as 20%to 40%of the cases,and the incidence of CvST has increased since the outbreak of the coronavirus disease 2019 *** with conventional anticoagulant or thrombolytic drugs,sonothrombolysis has the potential to remarkably shorten the required treatment time owing to the direct clot targeting with acoustic ***,previously reported strategies for sonothrombolysis have not demonstrated clinically meaningful outcomes(e.g.,recanalization within 30 min)in treating large,completely occluded veins or ***,we demonstrated a new vortex ultrasound technique for endovascular sonothrombolysis utilizing wavematter interaction-induced shear stress to enhance the lytic rate *** in vitro experiment showed that the lytic rate was increased by at least 64.3%compared with the nonvortex endovascular ultrasound treatment.A 3.1-g,7.5-cm-long,completely occluded in vitro 3-dimensional model of acute CVST was fully recanalized within 8 min with a record-high lytic rate of 237.5 mg/min for acute bovine clot ***,we confirmed that the vortex ultrasound causes no vessel wall damage over ex vivo canine *** vortex ultrasound thrombolysis technique potentially presents a new life-saving tool for severe CVST cases that cannot be efficaciously treated using existing therapies.
