The goal of this observational study is to evaluate safety and performance of GORE® ACUSEAL Vascular Graft for the treatment of CKD in patients with ESRD in hemodialysis. The main questions it aims to answer are: * Safety: Freedom from device-related infection adverse events at 24 months from device implant * Performance: Secondary patency at 24 months from device implant. Participants, after informed consent is obtained, will be implanted with GORE® ACUSEAL Vascular Graft and followed for 24 months in standard of care, to evaluate safety and performance of the device.
This is a European, Observational, Non-Interventional, Prospective, Non-Randomized, Single Arm, Multicenter, PMCF Registry to evaluate safety and performance of GORE® ACUSEAL Vascular Graft for the treatment of CKD in patients with ESRD in hemodialysis. There is no comparator device. The aim of study is to obtain real-world observational evidence about the use of the device. The AVG 22-09 registry consists of End-Stage Renal Disease (ESRD) patients who require hemodialysis access through Vascular Graft per the evaluating physician. A total of 72 subjects will be implanted in this registry with a limit of 25 subjects implanted per site. The registry has been designed with standard eligibility criteria to enroll subjects for which the registry device is intended to treat. Only patients who meet all of the inclusion criteria and none of the exclusion criteria will be implanted. All patients must provide informed consent prior to any registry related procedures being performed and the patient is considered enrolled when informed consent is obtained. The primary objective is to evaluate safety and performance of GORE® ACUSEAL Vascular Graft in hemodialysis access for the treatment of Chronic Kidney Disease (CKD) in patients with End Stage Renal Disease (ESRD). All patients who sign an informed consent will be considered enrolled and at the completion of study participation, subjects will be advised by their respective clinical centers on the appropriate follow up regimen to be followed but it is expected that the each implanted subject will be evaluated through hospital discharge and return for follow-up visits per site standard of care. Each enrolled and implanted subject will be followed for 24 months.

TERMINATEDPrimary Safety Endpoint. Number of subjects free from device-related infection at 24 months from device implant.
Events will be computed as follows: 1. All subjects who had a registry device related AE with an Infection MedDRA code within 730 days from device implant will be tabulated as 'Not Free from Infection'. 2. All subjects who completed the registry and were infection free at 24 months from the registry procedure will be considered free from device related infection. All relevant infection MedDRA terms will be agreed upon by the Office of Medical Affairs within Gore. This endpoint will be treated as a patient-based binomial proportion, and no formal hypothesis will be tested. A Kaplan Meir analysis will also be done to account for censoring.
Time frame: 24 months from device implant
Primary Performance Endpoint. Secondary Patency at 24 months: The time from device implant to complete abandonment of the access site for hemodialysis regardless of the number of interventions required to restore or maintain patency.
Events will be computed as follows: 1. All subjects who have an abandonment or explant of the registry graft within 730 days will have lost secondary patency. The date will be noted on the discontinuation form. 2. All subjects who completed the registry within 730 days without a graft abandonment will be considered patent. 3. If a subject did not complete the registry for a reason other than graft abandonment or explant, they will be censored. A Kaplan Meir analysis will be done to account for censoring.
Time frame: 24 months from device implant
Percentage of GORE® ACUSEAL Vascular Grafts cannulated within 1, 2, 3, 7, and 14 days from device implant.
The percentage of GORE® ACUSEAL Grafts cannulated within 24, 48,72,168, and 336 hours post device implant will be computed as follows: 1\. The hours from end time of procedure to the first successful hemodialysis session performed through the GORE® ACUSEAL Graft will be recorded per subject. This endpoint will be treated as a patient-based binomial proportion and will be summarized as percent with a 95% confidence interval.
Time frame: Cannulation within 1, 2, 3, 7 and 14 days from device implant.
Percentage of Subjects free from bleeding events through 6, 12, and 24 months from device implant.
1. All subjects experiencing an adverse event classified as bleeding prior to the end of the designated window will be counted as having a bleeding event within that interval. 2. Subjects not experiencing case 1, who have had a follow-up visit after the beginning of the designated interval, are declared as having no bleeding event. 3. All subjects not experiencing case 1 or 2 will not be included in computations for the corresponding interval. A Kaplan Meir analysis will be done to account for censoring.
Time frame: 6, 12, and 24 months from device implant
Secondary Patency at 6 and 12 months: The time from device implant to complete abandonment of the access site for hemodialysis regardless of the number of interventions required to restore or maintain patency.
Events will be computed as follows: 1. All subjects who have an abandonment or explant of the registry graft within 730 days will have lost secondary patency. The date will be noted on the discontinuation form. 2. All subjects who completed the registry within 730 days without a graft abandonment will be considered patent. 3. If a subject did not complete the registry for a reason other than graft abandonment or explant, they will be censored. A Kaplan Meir analysis will be done to account for censoring.
Time frame: 6 and 12 months from device implant.
Primary patency at 6, 12 and 24 months from device implant. Time interval of uninterrupted patency from device implant to the next access thrombosis or intervention.
Primary Patency will be calculated at 6 months, 12 months, and 24 months from device implant, and will use the following decision rules: 1. Subjects who have a repeat intervention, thrombosis event, abandonment or explant of the registry graft prior to the end of the analysis window will have lost patency. 2. Subjects who have not experienced case 1, and had a follow-up visit within the desired analysis window are considered patent. 3. All other subjects will be censored. A Kaplan Meir analysis will be done to account for censoring.
Time frame: 6, 12 and 24 months from device implant.
