Intravenous Intravascular Ultrasound for Arterial Visualization: A Feasibility Study

Abstract
The advent of endovascular grafting has created detailed imaging requirements for which intravascular ultrasound (IVUS) may be useful. Since intra-arterial IVUS imaging uses space within endovascular graft delivery systems and risks embolism, we investigated the use of intravenous IVUS imaging of arterial vasculature and endovascular grafts, a technique that appears not to have been previously described.
