WCN26-5490 EARLY POSTOPERATIVE FLEXION OF LOOP-CONFIGURED ARTERIOVENOUS GRAFTS: FOUR CASE ANALYSIS

Arteriovenous grafts (AVGs) for hemodialysis in a loop configuration offer the advantage of providing a wide puncture area. The elasticity of an AVG can differ depending on the implantation technique, even when the same material is used. Kinking or stenosis at the loop apex may occur intraoperatively or within two days postoperatively, typically in almost two patterns. One is caused by excessive curvature at the loop apex, and the other results from excessive redundancy (approximately 1–2 cm) at the artery and AVG anastomosis that secondarily affects the apex, leading to kinking.
