Delayed Recanalization of an Acutely Thrombosed Dialysis Arteriovenous Graft to Facilitate Effective Treatment for Perigraft Seroma: A Case Report.

This report describes a novel and effective salvage strategy for managing perigraft seroma complicated by a small-caliber expanded polytetrafluoroethylene arteriovenous graft (AVG). Our patient developed a persistent seroma near the arterial anastomosis following AVG placement. The patient underwent successful seroma removal and delayed graft recanalization after 1 week of spontaneous graft thrombosis, which permitted partial tissue incorporation. The treatment was successful, achieving complete resolution of the seroma and restoration of graft function. The patient has remained free of recurrence for 40 months of follow-up. This approach represents an effective strategy for treating perigraft seromas of hemodialysis grafts.
