How We Can Help
Dialysis Catheter Placement & Renal Biopsy Treatment Information
We provide several types of procedures, including:
- Arteriovenous (AV) fistula. This type of hemodialysis access consists of a connection between an artery and a vein in your arm or wrist. An AV fistula provides the needed blood flow, lasts for years and is less likely than other types of access to become infected or form clots. As a result, it is considered the “gold standard” of hemodialysis access. An AV fistula takes several weeks to develop after surgery.
- Arteriovenous (AV) graft. We create this type of hemodialysis access if an AV fistula will not develop. This might be the case if you have small veins. An AV graft uses a synthetic tube implanted under the skin to connect an artery with a vein. The graft serves as an artificial vein. Such a graft typically can be used within two to three weeks after placement. AV grafts are more prone to infections than are AV fistulas. However, if you keep the graft dry and clean, it can last for several years.
- Venous catheter. This type of access involves placement of a catheter with two chambers, allowing for two-way blood flow, into your neck, chest or leg. To hold the catheter in place, we may place a cuff under your skin. Catheters do not allow blood to flow as rapidly as other type of access do, and they have a higher chance of becoming infected. As a result, we typically use this type of access as a temporary solution when you need to start dialysis right away.
- Renal biopsy. We use a special needle or a surgical procedure to take a sample of kidney tissue for laboratory analysis. Ultrasound and computed tomography (CT) can help us sample specific areas during a needle biopsy. In the most common method, you lie on your stomach and we insert a needle into your back. You receive local anesthetic and light sedation before the procedure. It takes about 30 seconds to collect one tissue sample. We may need several samples. In some cases, we use another procedure to obtain the sample, depending on your condition and needs. For example, we may make an incision (cut) in your skin to obtain the kidney tissue. This procedure typically takes place under general anesthesia.
