In what situations is a permanent catheter used in dialysis?

A permanent catheter is typically used in dialysis for patients who have inadequate vascular access or are waiting for a fistula to mature. This situation is common among individuals who may not have suitable veins for creating a fistula immediately or who have issues that affect their vascular health, making traditional access methods unviable at that moment.

Permanent catheters provide a reliable means for hemodialysis treatment while the patient is in a transitional phase of care, such as waiting for a fistula to reach a point where it can be used reliably, which can take several weeks to months. They are designed for long-term use, allowing regular dialysis sessions without the need for frequent needle insertions, thus also ensuring that patients achieve sufficient dialysis efficiency.

While other options mention conditions under which a permanent catheter may be used, they do not accurately encapsulate the primary and most common indication for its use in patients undergoing dialysis.
