Interventions

EchoMark / EchoSuredevice

The EchoMark is to be secured a minimum of 3 cm away from the anastomosis. The follow-up EchoSure scans will be conducted by the designated EchoSure user without the investigator and without the sonographer/RVT conducting the Duplex exam in the room, either during the routine work-up prior to the surgeon seeing the patient or after. The EchoSure results for flow, and vessel depth and diameter are shown as numerical values on the screen of the EchoSure device.
