Understanding Dialysis Access
Dialysis is a life-saving treatment for individuals with kidney failure, as it helps remove waste and excess fluid from the blood. To undergo hemodialysis, a reliable access point is essential, typically created through surgery or minimally invasive procedures.
Endovascular AVF Creation
This innovative approach involves creating a connection between an artery and vein using minimally invasive methods, eliminating the need for traditional surgical incisions.
For suitable patients, endovascular AVF creation offers reduced pain, faster recovery, and a lower risk of complications compared to traditional surgery.
Dr. Lim’s expertise in this field makes him a trusted choice for patients seeking this advanced procedure.
Traditional Surgical AVF Creation
In some cases, traditional surgical AVF creation may be recommended, involving a surgical incision to connect an artery and vein. While effective, this approach may require a longer recovery period and carry a higher risk of complications.
Treatment Options for Dialysis Access
Dr. Lim provides personalized treatment plans tailored to each patient’s unique needs and preferences. Treatment options include AVF creation, arteriovenous graft (AVG) placement, and central venous catheter insertion.
The choice of access type depends on factors such as vascular health, anticipated duration of dialysis, and individual medical history.
Benefits of Endovascular AVF Creation
- Minimally invasive: Smaller incisions or no incisions, leading to less pain and scarring.
- Rapid recovery: Patients can resume their daily activities sooner.
- Lower risk: Reduced chance of infection and complications.
- Expertise: Dr. Lim’s extensive experience ensures the highest level of care.
Collaborative Approach
Dr. Lim will work closely with the patient, their renal physician, and their families to develop a comprehensive care plan. This collaborative effort ensures that all aspects of the patient’s health and well-being are considered and addressed throughout the treatment journey.

FAQ about Dialysis Access
The kidneys are like the body’s natural filtration system. They work around the clock to remove waste, toxins, and excess fluids from our blood, maintaining a healthy balance of minerals, like sodium and potassium.
End-stage renal failure refers to a condition where the kidneys have lost almost all of their ability to perform these vital functions. It’s a serious, life-altering diagnosis, and can bring a host of challenges and concerns. When the kidneys can’t perform their job properly, waste and excess fluid accumulate in the body, leading to a range of health issues, and that’s where haemodialysis comes in.
You will typically require renal replacement therapy such as haemodialysis or peritoneal dialysis, which necessitates creating a reliable access point in your body to perform the dialysis. Your kidney doctor will have a discussion with you on the most suitable modality for your situation. It’s understandable that this can be a challenging time for you, but rest assured, Dr. Lim and his team are here to support you.
Haemodialysis is like an external, artificial kidney. It’s a treatment that uses a machine to take over the filtering role of the kidneys. During a haemodialysis session, blood is pumped out of your body to an artificial kidney machine, and clean blood is returned back to your body. This process helps in maintaining the balance of the body by removing waste, salt, and extra water, preventing them from building up in the body. It also helps in maintaining a safe level of certain chemicals in your blood and helps to control blood pressure.
Why is it Necessary?
End-stage renal failure requires interventions like haemodialysis because, without the kidney’s natural functions, the body becomes overloaded with toxins and excess fluids. Without treatment, these imbalances can lead to severe complications, affecting nearly every system in the body, and can be life-threatening.
Having regular haemodialysis sessions can help manage the symptoms of end-stage renal failure, such as fatigue, nausea, weakness, and swelling, and improve the quality of life for individuals living with this condition.
Supportive Approach:
It’s important to know that while living with end-stage renal failure and undergoing haemodialysis can be challenging, many people lead full and active lives with the right care and support. Dr. Lim and his team are here to walk alongside you every step of the way, addressing your concerns, providing information, and offering support to help you manage your condition effectively.
While temporary catheters provide immediate access for haemodialysis, they are generally not suitable for long-term use due to the higher risk of infection and other complications. Dr. Lim recommends more permanent solutions like an arteriovenous (AV) fistula or graft for long-term haemodialysis, providing a safer and more effective means to facilitate treatment.
An arteriovenous (AV) fistula is a connection, surgically created by Dr. Lim, between an artery and a vein, usually in your arm. This connection allows blood to flow from the artery into the vein, causing the vein to grow larger and stronger, making it easier to insert the needles for haemodialysis. AV fistulas are preferred due to their lower infection risk and longer usability compared to other haemodialysis access options.
Most patients are suitable candidates for arteriovenous (AV) fistula creation; however, Dr. Lim will conduct a thorough examination, including vein mapping, to assess the quality of your vessels and determine whether an AV fistula is the right choice for you. In cases where the vessels are not suitable, other haemodialysis access options, like an AV graft or a catheter, may be considered.
The procedure to create an arteriovenous (AV) fistula is done under local or regional anaesthesia, meaning you should not experience pain during the surgery. After the procedure, there may be some discomfort or mild pain at the surgical site, which is usually well-managed with over-the-counter pain relievers. Dr. Lim will discuss pain management strategies with you to ensure your comfort throughout the process.
The maturation time for an arteriovenous (AV) fistula can vary, but it generally takes about 2 to 3 months for it to be ready for use. During this period, Dr. Lim and his team will monitor the development of your fistula to ensure it is maturing properly and will advise you when it is suitable for haemodialysis.
Dr. Lim will provide comprehensive instructions on caring for your arteriovenous (AV) fistula post-surgery. This typically includes keeping the site clean and dry, avoiding carrying heavy objects with the arm where the fistula is located, and regularly checking for the “thrill” or vibration at the fistula site to ensure proper blood flow. Timely reporting of any abnormalities or complications is crucial in maintaining the functionality of your AV fistula.
Yes, once the surgical site has healed and the fistula has matured, you should be able to use your arm normally. However, it is essential to avoid activities that can put excessive pressure on the fistula arm, like lifting heavy objects, to prevent any complications. Dr. Lim will guide you on the do’s and don’ts for maintaining the health of your fistula.
When properly cared for, an arteriovenous (AV) fistula can last for several years, and some patients have used theirs for over a decade. Regular monitoring and healthy lifestyle choices play a crucial role in maintaining the functionality of your AV fistula. Dr. Lim will provide guidance on care and maintenance to help ensure the longevity of your fistula.
It’s normal for an arteriovenous (AV) fistula to appear more pronounced or look “funny” as it matures. This is due to the increased blood flow causing the vein to enlarge and thicken. While it might look different, a mature and pronounced AV fistula is actually beneficial as it facilitates easier and more efficient needle insertion during haemodialysis.
Arteriovenous (AV) fistula can sometimes face complications like narrowing or clotting, which can impede blood flow, making it challenging to perform haemodialysis. Dr. Lim can evaluate your fistula to identify any issues and recommend interventions like angioplasty or thrombectomy to restore proper function.
If you notice any abnormalities like swelling, redness, a change in the “thrill,” or other signs of malfunction, it is crucial to inform Dr. Lim or your healthcare provider promptly. Early detection of issues allows for timely intervention and can help in preserving the functionality of the arteriovenous (AV) fistula.
