What is AV Fistula For Dialysis?

AV fistula for dialysis surgery is the process of creating connections between an artery with a vein referred to as an arteriovenous (AV) fistula, in order to offer a high-flow artery access point for hemodynamic therapy. A AV fistula for dialysis usually is made in the arm by connecting the vein directly to an artery nearby. The connection causes the vein to expand and become stronger, making it simpler to insert dialysis needles and providing a stable long-term source of access. Fistulas AV are considered to be the best option for dialysis access because of their durability, lower chance of getting infections, and superior overall performance when compared to other methods of access like central vein catheters.

Who Performs Your Surgery?

The Chirayu Super Speciality Hospital creation of an AV fistula for Dialysis is carried out by experienced Vascular surgeons that specialize in access to dialysis procedures. Our team is educated in the most advanced surgical techniques and collaborates with dialysis specialists and nephrologists to provide comprehensive treatment. Our surgeons concentrate on safety of patients, reducing complications, and creating top-quality AV fistulas to support efficient dialysis treatment.

Types of AV Fistula Surgery

• Radiocephalic Fistula AV : This is by far the most frequent type of fistula that occurs through the connection of radial arterial with the vein of cephalic within the wrist. It is typically the first option for dialysis access because of its location and its accessibility.
• Brachiocephalic AV Fistula : In this form brachial artery, it is linked to the cephalic artery near the elbow. This is done when wrist veins aren’t appropriate or were previously used to treat other fistulas.
• Transposed Brachio-Basilic AV Fistula : The process involves connecting the brachial vein to the basilic vein. The vein is then surgically repositioned to the skin’s surface in order to facilitate gain access to dialysis. This procedure is employed when brachiocephalic or radiocephalic options are not possible.

Symptoms Indicating the Need for Dialysis Access Surgery

• Diagnosis of chronic kidney disease (CKD) or end-stage renal disease (ESRD) needing regular hemodynamics.
• Dialysis access issues that exist including failure of AV grafts, or frequent infections in central vein catheters.
• A long-term, reliable and long-lasting access point to continuous dialysis treatment.
• The following recommendations are from nephrologists and health professionals regarding the creation of AV fistulas.

Diagnosis for Dialysis Access Surgery

The diagnosis and evaluation of AV fistula for dialysis surgery usually involves an exam of the arms of the patient to evaluate artery and vein quality. Ultrasound imaging is a method to trace the veins and arteries, giving precise information on their flow, size, and their suitability for the creation of fistulas. Based on these measurements the vascular surgeon will determine the best kind of AV fistula as well as the best location for surgery.

Treatment Process

The procedure begins with a consult with a vascular surgeon to talk about the process, its advantages and risk. AV fistula for dialysis is generally performed as an outpatient under local anesthesia, and sometimes with the aid of sedation. During the operation the surgeon will make an incision of a tiny size in the arm to join an artery with an artery, creating a fistula. The procedure generally takes about around 1-2 hours. Patients are usually able to return home the next day. Following surgery the fistula must have time to grow, typically between 6 and 12 weeks, before it is able to be used to dialysis.

Care and Recovery After Surgery

The post-operative care is vital to the long-term success and durability of the AV fistula for dialysis. Patients are advised to stay away from any strenuous lifting or activities using the arm on which the fistula formed. Monitoring the fistula regularly for signs of maturation, like the strong heartbeat and a “thrill” sensation, is crucial. Patients must keep the area clean and follow the instructions from their surgeon to avoid infections. The follow-up appointment will be scheduled to assess the progress of the fistula as well as the readiness to undergo dialysis.
