A Port-a-Cath is a commonly used method for accessing a patient's blood during dialysis. This device is a type of central venous catheter that is implanted under the skin and connects to a vein, typically in the chest area. It allows for easy and repeated access to the bloodstream, which is essential for hemodialysis treatments. The Port-a-Cath can remain in place for long periods, making it a convenient option for patients requiring chronic dialysis therapy.

Other methods, while used in specific situations, are not as commonly employed for regular dialysis access. A hemodialysis shunt is sometimes mentioned, but it typically refers to older techniques that have largely been replaced by more modern access methods, such as arteriovenous (AV) fistulas or grafts. An external femoral catheter is generally used in acute settings and is less preferred for long-term dialysis due to the risk of complications. An intraosseous line is typically reserved for emergencies and is not suitable for dialysis access.
