Vascular access intervention therapy (VAIVT) is an interventional therapy that is an essential part of dialysis as it allows for long-term continuous vascular access (VA). This Guideline is intended to serve as an aid for solving of actual technical problems encountered when performing VAIVT. After reviewing the basics of VAIVT, we listed the various VAIVT techniques in clinical question (CQ) format and provided descriptions. Specifically, these descriptions contain the indications, contraindications, VA tests, methods of using VAIVT devices, complications associated with VAIVT, and most of the issues related to VAIVT measures and practices. We also ensured that contents were consistent with the Guideline of Vascular Access Construction and Repair for Chronic Hemodialysis produced by the Japanese Society for Dialysis Therapy. We hope that this Guideline is useful to medical practitioners involved in VAIVT and contribute to maintaining vascular access for dialysis patients.
