The following punishment was reviewed by gore: title: delamination of acuseal early cannulation arteriovenous graft months after implantation source: j vasc access.2021 sep;22(5):840-844, corresponding author: kotaro suemitsu.Abstract: arteriovenous fistula is recommended, but arteriovenous graft is acceptable when a fistula is not possible.Acuseal is an early cannulation graft with a trilayer structure.Although primary patency rates of acuseal appear to be similar to those of other standard grafts, few studies have investigated long-term results and complications.In our series, delamination of the wall structure occurred in 5.1% (6/115) by 21 months after acuseal implantation.The causes could be divided into cannulation-related and cannulation-unrelated.Here, we describe the six cases in which delamination of the wall structure occurred in the medium term after acuseal implantation.Case patient 3: a 66-year-old male had a 6.0 mm acuseal implanted in his left forearm (loop graft; inflow, proximal radial artery; outflow, median cubital vein).He started hemodialysis 2 days later.Occlusion was noted 7 months after avg implantation and vaivt was required.At this time, no delamination of the avg was observed.Three months after vaivt, however, delamination of the posterior wall of the venous puncture site was detected by ultrasound.There was no vaivt.He died 3 months later.

Patient and event information were requested, but author declined to provide any details.As a result, further investigation was not possible.The instructions for use state: the gore® acuseal vascular graft can be cannulated early (within 24 hours after implantation).Patients should be carefully monitored when using gore® acuseal vascular grafts for vascular access.Puncture sites must be adequately separated when repeated needle punctures of the graft are necessary.Multiple punctures in the same area may lead to disruption of the graft material or formation of a perigraft hematoma or pseudoaneurysm.Cbas® heparin surface incorporates carmeda heparin manufactured from heparin sodium api, which is covalently bound to the device surface and is essentially non-eluting.
