What does "Old fistula vein" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
An "old fistula vein" refers to a vein that has been used for a long time for medical procedures, typically for dialysis in patients with kidney disease. Dialysis is a treatment that cleans the blood when the kidneys can't do their job. A fistula is created by connecting a vein and an artery, usually in the arm, which makes the vein larger and stronger so it can handle repeated needle insertions for the dialysis process. Over time, this vein can become "old" or worn out due to the frequent use.
