Abstract

We utilized intravascular ultrasound (IVUS) imaging in a canine pulmonary embolism model to visualize experimental emboli. The images obtained were compared with those obtained by single-plane pulmonary arteriography in each of six animals. The vessel lumen appeared patent by both methods prior to injection of autologous clot. After thrombi were injected, the vessels were again imaged using both techniques. Intravascular ultrasound was 100 percent sensitive in detecting emboli, and visualization was always rapid. There were no complications. It appears that IVUS imaging is a sensitive method for documenting the presence of clot in a canine pulmonary embolism model.
