Seroma as a Rare Complication of Autologous Arteriovenous Fistula Creation in the Forearm of a Hemodialysis Patient: A Case Report.

This seroma was associated with postoperative dead space, surgical technique, and patient clinical status. Sufficient preoperative ultrasonographic vascular mapping is required to avoid inappropriate handling of veins and prevent seroma formation. Postoperative ultrasonographic follow-up is recommended due to the future risk of fistula dysfunction and infection associated with seroma enlargement, which may necessitate surgical seroma excision.
