Dialysis Access at CritiCare Asia Hospitals, Malad
Haemodialysis needs a dependable route for blood to leave the body, pass through the filter, and return, often several times a week, and that route is called dialysis access. CritiCare Asia Hospitals is a vascular surgery hospital in Mumbai where vascular surgeons and nephrologists plan access together around each patient's veins and treatment timeline. A new fistula needs weeks to months to mature before needles can be used safely. For that reason, it cannot be left as a last-minute step, and families cope better when the plan is made early. AV fistula treatment in Malad, Mumbai is therefore best started well before kidney function falls to the point where dialysis begins.
Signs That Call for Attention
Some signs tell you it is time to plan access, while others suggest an existing fistula needs to be looked at.
- Kidney function that keeps falling, with the nephrologist expecting dialysis in the future
- Swelling, tiredness or a poor appetite as kidney disease advances
- The "thrill", the soft buzzing felt over a healthy fistula, fading or disappearing
- Redness, warmth, pain or discharge around the access site
- A swollen arm, or a bulge along the line of the fistula
- Poor flow or repeated needle trouble during dialysis
A fistula that suddenly turns quiet or hard, or a site that looks infected, needs to be seen the same day.
Understanding AV Fistulas
An arteriovenous (AV) fistula is a surgical connection between an artery and a vein, usually in the arm. The extra blood flow slowly widens and strengthens the vein, a process called maturation. Once it has matured, the fistula can handle repeated needle insertions over many years of dialysis.
Where the veins allow, a fistula is usually preferred because it carries a lower risk of infection and clotting than a graft (an artificial tube) or a catheter (a thin tube placed in a large vein). It does not suit everyone, so the AV fistula specialists in Malad, Mumbai look at the following before deciding:
- Whether the veins are wide enough and have healthy walls
- How well the artery delivers blood, since maturation depends on it
- General blood vessel health, which diabetes and peripheral vascular disease can affect
- Which arm is dominant and how the patient's day is organised, as the non-dominant arm is chosen where possible so daily tasks are less disturbed
Planning and Creation of an AV Fistula
Before AV fistula surgery in Malad, Mumbai, the team maps the arteries and veins of the arm with ultrasound. This shows where a fistula can be placed and whether one is possible at all. The operation is usually done under local anaesthesia, with the surgeon joining the chosen artery and vein directly.
After surgery, the arm is watched to see that the fistula matures as expected, and the site needs careful handling to avoid infection and clotting. Patients, and the family members who help at home, are shown how to feel for the thrill each day.
Complications and Monitoring
A fistula is not a one-time fix, and it needs regular checking over the years. The problems that can arise include:
- Failure to mature, where the vein never becomes wide or strong enough for dialysis needles
- Stenosis, a narrowing at or near the join that reduces blood flow
- Thrombosis, a clot that blocks the fistula and stops it working
- Infection at the access site, which needs treatment without delay
- Aneurysm, a bulge in the vein wall that can develop from repeated needling
Seeing the same team at regular check-ups means changes are noticed early and treated early. This helps the fistula last longer and reduces the chance of repeat procedures.
Treatment Options for Dialysis Access
An AV fistula is the usual first choice. If the veins are unsuitable, a graft or catheter can be used, and the team explains what each option involves so the family can take part in the decision. When an existing fistula develops a problem, treatment depends on the cause. A narrowed segment may be opened with angioplasty, in which a small balloon is inflated inside the vessel, or revision surgery may be considered. Clots and infection need prompt treatment to protect the access.
