DIALYSIS ACCESS MANAGEMENT

At EVA we maintain and preserve the access sites used for hemodialysis or peritoneal dialysis. Our dialysis access management includes monitoring, evaluation, and interventions to ensure optimal function and longevity of the dialysis access site, which may be an arteriovenous fistula (AVF), arteriovenous graft (AVG), or a peritoneal dialysis catheter.

ANGIOPLASTY

At EVA we treat narrowed or blocked blood vessels, typically arteries. Our treatment involves the use of a balloon-tipped catheter that is inserted into the affected blood vessel. Once in position, the balloon is inflated, widening the vessel and improving blood flow. Angioplasty is commonly performed to treat conditions such as coronary artery disease, peripheral artery disease, and renal artery stenosis.

FISTULOPLASTY

Fistuloplasty is a surgical procedure performed to repair or improve the function of an arteriovenous fistula (AVF) or arteriovenous graft (AVG) used for hemodialysis. It involves the use of various techniques to open and expand the narrowed or blocked area within the AVF or AVG, allowing for better blood flow and more efficient dialysis.

FISTULOGRAM

At EVA we use fistulogram diagnostic imaging procedure to visualize and assess the condition of an arteriovenous fistula (AVF) or arteriovenous graft (AVG) used for hemodialysis. It involves the injection of a contrast dye into the access site, followed by X-ray imaging. The fistulogram helps identify any blockages, stenosis, or other abnormalities within the AVF or AVG.

THROMBECTOMY

Thrombectomy is performed to remove a blood clot (thrombus) from a blood vessel. It is commonly used in the treatment of acute arterial occlusions, where a clot restricts or blocks blood flow.

TUNNELED DIALYSIS CATHETERS

A EVA we offer tunneled dialysis catheters. These are specialized catheters inserted into a large vein, typically in the neck or chest, for hemodialysis. These catheters have a cuff that secures them in place and a tunnel under the skin to prevent infection. Tunneled dialysis catheters provide temporary access for dialysis when other forms of vascular access (such as AVFs or AVGs) are not immediately available or suitable.

ENDOVASCULAR STENTS

At EVA we offer endovascular stents. These are small, expandable mesh-like devices inserted into blood vessels to provide structural support and maintain vessel patency. They are commonly used in angioplasty procedures. When the balloon is inflated during angioplasty, the stent expands and is left in place to keep the vessel open, preventing it from collapsing or re-narrowing. Endovascular stents can be made of metal or synthetic materials and are used to treat conditions like coronary artery disease, peripheral artery disease, and stenosis in various blood vessels.

VENOUS MAPPING

Venous mapping is a procedure that involves the systematic examination and visualization of the veins within a specific area of the body. It is typically performed using non-invasive imaging techniques to create a detailed map or image of the veins.

The purpose of venous mapping is to assess the size, location, and condition of the veins in order to determine their suitability for various medical procedures. It is commonly used in situations where accurate knowledge of the venous system is crucial, such as prior to surgery, during the planning of venous access procedures, or for the diagnosis and treatment of venous disorders.

The most commonly employed imaging modalities for venous mapping include ultrasound and venography. Ultrasound uses high-frequency sound waves to create real-time images of the veins, providing information about their diameter, depth, and blood flow. Venography involves the injection of a contrast agent into a vein, which is then visualized using X-ray imaging. This technique allows for the detailed examination of the veins’ structure and the identification of any abnormalities or blockages.

Venous mapping is particularly useful in situations where the veins may be difficult to locate or access, such as in patients with obesity, those with a history of intravenous drug use, or individuals with vascular malformations. By accurately mapping the venous system, healthcare professionals can plan and perform procedures more effectively, reducing complications and improving patient outcomes.
