Overview
Your Dialysis Lifeline
For patients with end-stage kidney disease, hemodialysis is a life-sustaining treatment. But dialysis can only work if there is reliable vascular access — a way to connect your bloodstream to the dialysis machine. When the kidneys fail, that access point becomes a lifeline, enabling the efficient exchange of blood between your body and the machine that filters waste.
Dr. Ayar specializes in the full spectrum of dialysis access care — from creating new access sites to maintaining and repairing existing ones. Our goal is to ensure you never miss a dialysis session due to access problems.
We work closely with your nephrologist and dialysis center to coordinate your care and keep your access functioning optimally for years to come. Many of our patients also have underlying peripheral arterial disease (PAD) or circulation problems such as claudication, which we evaluate and manage alongside your dialysis access.

Access Types
Types of Dialysis Access
Dr. Ayar will recommend the best access type based on your anatomy, health status, and dialysis schedule.
Arteriovenous (AV) Fistula
The gold standard for dialysis access — a surgically created connection between your own artery and vein that strengthens the vein over time. Preferred for long-term use because it lasts longest and carries the lowest risk of infection.
AV Graft
A synthetic tube connecting an artery and vein, used when your own vessels aren't suitable for a fistula. Grafts mature faster than fistulas and provide reliable access with proper maintenance and monitoring.
Tunneled Dialysis Catheter
A catheter placed in a large vein for immediate dialysis access — used as a bridge while a fistula or graft matures, or when other options aren't available. Requires close monitoring for infection.

The Role of Dialysis Access Management
The goal of dialysis access management is to maximize the life and health of the access point, ensuring effective hemodialysis access. This involves:
1. Surveillance: Regular monitoring for signs of dysfunction, such as narrowing (stenosis) or clotting, which can decrease the efficiency of dialysis. Surveillance is a key part of dialysis access procedures to detect issues early.
2. Maintenance: Addressing any issues promptly, often using minimally invasive access interventions such as angioplasty or thrombectomy to improve or restore flow. Maintenance may also include other dialysis access procedures to keep the access functioning optimally.
3. Intervention: Providing necessary access interventions to repair or revise the access point, including procedures like stent placement or fistula salvage. This can also include the decision to create a new access point through appropriate dialysis access procedures if current ones are no longer viable.
4. Education & Support: Helping patients understand the care and preservation of their hemodialysis access points, and providing guidance for recognizing potential complications.
What conditions does dialysis access management help treat?
Dialysis is a common treatment for patients with kidney failure or complications. When the kidneys fail, patients may require hemodialysis or peritoneal dialysis, each needing a specific type of access. Hemodialysis typically involves artificial blood vessel connections, while peritoneal dialysis requires the placement of a peritoneal dialysis catheter (PD catheter) to enable internal fluid exchange. Managing these access points, including vascular access and PD catheters, ensures they remain in good working order and helps prevent issues like vessel clogging from clotting or coagulation, as well as narrowing of the connection, which can occur over time with regular dialysis.
Dialysis treatments commonly used on patients who suffer from renal/kidney disease help keep them alive through highly frequent sessions using an array of specialized equipment, including fake blood vessel attachments and peritoneal dialysis catheters. When connected properly, this apparatus allows the body’s functions (especially fluid movement) to remain unaffected while preventing clogs and helping manage associated issues such as leg swelling (edema).
When To Call Us
Warning Signs Your Access Needs Attention
Dialysis access problems often worsen quickly. If something feels off, it is worth getting checked — many issues can be treated with minimally invasive procedures when caught early, helping you avoid missed treatments and more serious complications.
Weak or inefficient dialysis sessions (low flow, alarms, or trouble completing treatment)
A weaker or absent "thrill" or vibration over the access site
Pain, swelling, bleeding, or bruising around your fistula, graft, or catheter
Signs of infection — redness, warmth, drainage, or fever near the access
Repeated clotting or a sudden access blockage
Coolness, numbness, or pain in the hand on the side of your access
If your access stops working or you notice signs of infection, contact us right away. Early evaluation can prevent access failure, missed dialysis sessions, and serious complications.
What We Offer
Comprehensive Access Services
From creation to repair, we handle every aspect of your dialysis access care.
Access Creation
Dr. Ayar creates AV fistulas and places AV grafts using minimally invasive techniques to establish reliable, long-lasting dialysis access tailored to your anatomy.
Fistulogram & Angioplasty
Imaging of the access site to identify narrowing or blockages, followed by balloon angioplasty to restore adequate blood flow — usually in the same visit.
Thrombectomy
Removal of blood clots from a thrombosed fistula or graft to restore function quickly and avoid the need for a new access site.
Catheter Placement & Exchange
Placement or replacement of tunneled dialysis catheters when immediate access is needed, when a catheter is infected, or when other access sites are unavailable.
Access Surveillance
Regular monitoring of your access site to detect problems early — before they cause access failure or missed dialysis sessions.
Steal Syndrome Treatment
Treatment for dialysis access steal syndrome, where blood is diverted away from the hand, causing pain, numbness, or tissue damage.

FAQS
Frequently Asked Questions About Deep Vein Thrombosis
What is dialysis access management?
Dialysis access management is the full process of creating, monitoring, maintaining, and repairing the vascular access point that connects a dialysis patient's bloodstream to the dialysis machine. Because hemodialysis can only work with reliable access, managing that access well — keeping it open, clot-free, and infection-free — is what allows patients with kidney failure to receive consistent, effective treatment. At Coastal Vascular Center, Dr. Ayar handles every stage of access care for patients in Pearland, Lake Jackson, and throughout the Houston region.
What are the types of dialysis access?
There are three main types. An arteriovenous (AV) fistula is created by surgically joining an artery to a vein — it is the preferred long-term option because it lasts longest and has the lowest infection risk. An AV graft uses a synthetic tube to connect an artery and vein when your own vessels are not suitable for a fistula. A tunneled dialysis catheter is placed in a large vein for immediate or short-term access, often as a bridge while a fistula or graft matures. Dr. Ayar will recommend the best option for your anatomy and treatment timeline.
How long does an AV fistula take to mature before it can be used?
An AV fistula typically needs about 6 to 8 weeks to mature — the increased blood flow strengthens and enlarges the vein so it can handle repeated needle insertions. During that time, a temporary catheter may be used if dialysis must begin sooner. A graft usually becomes usable within about 2 to 3 weeks. Regular surveillance during and after maturation helps confirm the access is developing properly.
What are the warning signs that my dialysis access is failing?
Contact us right away if you notice weak or inefficient dialysis sessions (low flow, alarms, or trouble completing treatment), a weaker or absent "thrill" over the access site, pain, swelling, bleeding, or bruising around your fistula, graft, or catheter, or signs of infection such as redness, warmth, drainage, or fever. Access problems can worsen quickly, but many can be treated with minimally invasive procedures when caught early — often without needing a new access site.
What is a fistulogram and do I need one?
A fistulogram is an imaging study of your dialysis access that shows how well blood is flowing and whether there is any narrowing (stenosis) or blockage. It is often paired with angioplasty in the same visit — if a narrowing is found, a small balloon opens it and restores flow. If your dialysis team notices reduced flow, difficulty completing sessions, or frequent clotting, a fistulogram is usually the next step. Most fistulograms are performed in the office and you can typically return to dialysis quickly.
Can a clotted fistula or graft be saved?
In many cases, yes. A procedure called a thrombectomy removes the clot and restores blood flow, often avoiding the need to create a brand-new access site. Speed matters — the sooner a thrombosed access is treated, the better the chance of saving it. If your access stops working, call our office immediately; we prioritize urgent access cases at both our Pearland and Lake Jackson locations.
Is dialysis access management covered by insurance?
Because dialysis access is essential to a medically necessary treatment for kidney failure, access creation, surveillance, and medically necessary interventions are generally covered by insurance and Medicare. Our team verifies your benefits and documents medical necessity for any recommended care, and we will help you understand your coverage before you proceed.
