A practical, type-specific guide to the three main hemodialysis vascular access types — arteriovenous (AV) fistula, AV graft, and central venous catheter (CVC) — and the wardrobe choices that fit each. Sourced from National Kidney Foundation patient education, NIDDK clinical guidance, and consistent themes across long-term patient feedback.
The three main hemodialysis access types each have different wardrobe implications. AV fistula (typically in the upper arm or forearm) needs sleeves that open for access without compressing the fistula. AV graft (similar location to fistula but with a synthetic tube) has the same wardrobe needs as fistula. Central venous catheter (CVC) sits in the upper chest and exits through the skin; the wardrobe is more like chemo port-access — the catheter must stay covered, dry, and clean, with a top that opens at the chest. Below: each access type and the right wardrobe.
The three access types
Per National Kidney Foundation’s vascular access guidance:
Arteriovenous (AV) fistula
Surgically connects an artery to a vein, typically in the non-dominant forearm or upper arm. The vein “matures” over 6-12 weeks, becoming large enough to support dialysis needles. The fistula is the longest-lasting access (years to decades), the lowest-infection access, and the gold standard. Visible as a slightly raised, palpable “bruit” or “thrill” along the access site.
AV graft
A synthetic tube connecting an artery to a vein in the same general area as a fistula. Used when the patient’s veins aren’t suitable for direct fistula creation. Lasts 3-7 years typically; higher infection risk than fistula but lower than catheter.
Central venous catheter (CVC) — “tunneled” or “permcath”
A catheter placed in a large vein (usually internal jugular) with the external port exiting through the upper chest. Used as a temporary access while a fistula or graft matures, OR long-term in patients without other options. Highest infection risk; per NKF, fistulas and grafts are preferred when possible.
Dressing for AV fistula or graft
The fistula/graft requires:
Long-sleeve top with upper-arm zip access
A short zip running along the outer seam of the upper arm lets the nurse expose the access without disturbing the rest of the sleeve. Inspired Comforts dialysis tops use this design. Cost: $35-70.
Dressing for central venous catheter (CVC)
The CVC is fundamentally different — the access is in the chest, not the arm. Wardrobe needs:
Snap-front or chest-zip top, similar to chemo port-access designs
A snap or zip running across the upper chest where the catheter exits lets the nurse access the catheter in seconds. Many CVC patients use chemo port-access shirts; the design is identical. Port-access tops work for CVC patients.

Comparison table
| Feature | Fistula / graft | Catheter (CVC) |
|---|---|---|
| Access location | Arm (forearm or upper arm) | Chest (upper chest) |
| Best top design | Upper-arm zip access | Chest snap or zip |
| Showering | Wash normally; pat dry around access | Waterproof cover required |
| Swimming | OK once mature; consult nephrologist | Generally no |
| Sleeping | Avoid arm-side sleeping | Avoid chest pressure on catheter |
| BP cuff | NEVER on access arm | Either arm OK |
| Heavy lifting | OK 6+ weeks post-creation; not on access arm | Avoid; catheter can dislodge |
| Compression sleeves | NEVER on access arm | OK |
Universal rules — all access types
The recovery clothing piece
The Inspired Comforts dialysis collection covers fistula and graft (upper-arm zip), and the chemo collection covers catheter access (chest zip). Match the design to your access type, not the marketing.
