Enhanced vascular assessment by ultrasound using microbubble contrast after percutaneous decannulation of peripheral veno-arterial extracorporeal membrane oxygenation.

ABSTRACT

Termination of peripheral veno-arterial extracorporeal membrane oxygenation support by managing the arteriotomy wound using a percutaneous closure device was reported successful and effective. However, careful assessment by clinical examination and also ultrasound Doppler assessment of the lower limb vasculature after closure is of paramount importance. Complications including pseudoaneurysm, arterial stenosis, and acute thrombosis are not uncommon. In this case report, commercial microbubbles were used as ultrasound contrast to enhance the image quality for better vascular ultrasound and Doppler assessment after veno-arterial extracorporeal membrane oxygenation percutaneous decannulation. A peudoaneurysm was revealed after microbubble injection, which would otherwise be missed.
