Targeted Venous Occlusion Using Pulsed High-Intensity Focused Ultrasound

Targeted Venous Occlusion Using Pulsed High-Intensity Focused Ultrasound IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING Hwang, J. H., Zhou, Y., Warren, C., Brayman, A. A., Crum, L. A. 2010; 57 (1): 37-40

Abstract

Targeted vascular occlusion is desirable for clinical therapies such as in the treatment of esophageal and gastric varices and varicose veins. The feasibility of ultrasound-mediated endothelial damage for vascular occlusion was studied. A segment of a rabbit auricular vein was treated in vivo with low duty cycle, high peak rarefaction pressure (9 MPa) high-intensity focused ultrasound pulses in the presence of intravenously administered circulating microbubbles, followed by fibrinogen injection, which resulted in the formation of an acute occlusive intravascular thrombus. Further investigation and refinements of treatment protocols are necessary for producing durable vascular occlusion.
