TABLE 1.
Summary of three types of vascular access in hemodialysis.
Access type | Advantages | Challenges/Limitations | Clinical uses | Patient outcomes/Success rates | Citation |
---|---|---|---|---|---|
AVF | High patency rates, lower complication rates | - Lengthy maturation process - High failure rates of maturation - Around 55% usability within 4 months in the US |
Preferred if patient’s vasculature is suitable | - Infection rate: 0.5%–1.5% perpatient-year - High primary unassisted patency rate: e.g., 57% and 71% for female and male patients after 5 years - Less likely to be abandoned |

AVG | Suitable for patients with unsuitable vessels for AVF, reliable access | - Prone to neointimal hyperplasia - Complications at graft-vein anastomosis |
Used when AVFs are not viable | - Infection rate: 13% - Primary patency at 2 years ∼40%, Secondary patency ∼60% |

CVC | Immediate access, temporary solution | High rates of infection, thrombosis, and vein stenosis | Used when other options are not feasible | - Primary patency failure: 91% within the first year - Highest infection and complication rates among the three |
