Contraindications for Arteriovenous Fistula as Hemodialysis Access
AVF creation should be avoided when there is absence of suitable vessels due to severe arterial occlusive disease or noncorrectable central venous outflow occlusion, multiple prior failed AV accesses with no remaining options, or in infants/children with prohibitively diminutive vessels. 1
Absolute Anatomic Contraindications
The 2019 KDOQI guidelines clearly define situations where AVF creation is not feasible:
- Severe arterial occlusive disease preventing adequate inflow
- Noncorrectable central venous outflow occlusion (e.g., superior vena cava syndrome, subclavian vein occlusion that cannot be corrected)
- Prohibitively diminutive vessels in infants and children where vessel size is inadequate
- Exhaustion of all upper extremity AV access options with unsuitable vessel characteristics 1
These represent true anatomic barriers where the vascular infrastructure cannot support a functioning fistula.
Relative Contraindications Based on Patient Circumstances
Limited Life Expectancy
When anticipated survival is very short (though specific timeframes are not defined in guidelines), a CVC may be more appropriate than subjecting the patient to AVF creation surgery with its maturation period of weeks to months 1. The risk-benefit calculation shifts when the patient is unlikely to benefit from the long-term advantages of an AVF.
Valid Patient Preference Affecting Quality of Life
AVF may be contraindicated when its use would severely limit quality of life or achievement of life goals, but only after the patient has been properly informed of patient-specific risks and benefits of all reasonable access options 1. This is not a blanket excuse to avoid AVF—it requires documented informed decision-making about how the access would impact the patient's specific life circumstances.
Anticipated Near-Term Transplantation
When a living donor transplant is confirmed with an operation date in the near future (e.g., <90 days), a temporary CVC is more appropriate than creating an AVF that may never be used 1. This preserves vessels and avoids unnecessary surgery.
Clinical Scenarios Favoring Alternative Access
Severe Cardiac Disease
While not explicitly listed as a contraindication in the guidelines, the literature notes that high-flow AVFs (>2000 mL/min, particularly proximal fistulas) can precipitate or worsen congestive heart failure 2, 3. In patients with severe pre-existing cardiac dysfunction, careful consideration of cardiac status should influence access type selection, potentially favoring lower-flow options or grafts over high-flow native fistulas.
Steal Syndrome Risk Factors
Patients with severe peripheral arterial disease, diabetes with vascular complications, or elderly patients with poor distal perfusion are at higher risk for ischemic steal syndrome 3. While not absolute contraindications, these factors require careful preoperative vascular assessment and may favor more distal access sites or alternative access types.
Important Caveats
Multiple prior AVF failures alone do not contraindicate another attempt unless truly no anatomic options remain. The guidelines emphasize exhaustive evaluation of all potential sites (including lower extremity options when upper extremity is exhausted) before declaring a patient unsuitable for AV access 1.
Poor vessel quality on mapping is not an absolute contraindication but requires expert surgical judgment. The choice between AVF and AVG should be based on the operator's clinical assessment of vessel characteristics, not rigid criteria 1.
The key principle is that contraindications are primarily anatomic (no suitable vessels) or circumstantial (life expectancy, imminent transplant, informed patient preference affecting QOL). Age, diabetes, and comorbidities alone are not contraindications—these patients should still be evaluated for AVF creation with appropriate preoperative vascular mapping and surgical planning 4.
