Automated 3D Ultrasound-based Surveillance of Arteriovenous Fistula Maturation for Post-operative Hemodialysis Patients

Automated 3D Ultrasound-based Surveillance of Arteriovenous Fistula Maturation for Post-operative Hemodialysis Patients

This is a two stage, prospective, multi-center study to evaluate the EchoMark and EchoSure devices in patients undergoing peripheral arteriovenous fistula creation for hemodialysis access.

This is Stage 1 of a 2 stage protocol, targeting to enroll 60 patients in prospective, single arm, non-randomized, multi-center observational study to record objective data in patients undergoing upper extremity arteriovenous fistula construction with autologous tissue for the purpose of eventual hemodialysis access, in whom the EchoMark is placed at the site of vascular anastomosis. Follow-up visits include EchoSure and duplex imaging.

Inclusion Criteria:

• Age > 18 years
• Patients presenting for upper extremity arteriovenous fistula construction with autologous tissue for the purpose of eventual hemodialysis access where the surgeon has selected EchoMark and EchoSure as the optimal method of vascular monitoring based on clinical assessment and plan
• Patient is able to sign informed consent and able to participate in all testing associated with this clinical investigation
• Women of childbearing potential have a negative pregnancy test

Exclusion Criteria:

• Age <18 years old
• Patient unable to sign informed consent
• Patient participating in another investigational device or pharmacological study
• Prisoner or patient from vulnerable populations as defined in 45 CFR 46.
