Dialysis Management Santa Fe
Stent placement Albuquerque or catheter access stenting can be used for kidney disease patients on dialysis to prevent blockage of the fistulas, which are abnormal blood vessels that connect the veins in your arm with your kidney. Your doctor will determine whether it’s right for you based on your medical history and condition. If they feel this procedure may benefit you, they will schedule an appointment with one of the experienced urologists at Saint Joseph’s Dialysis Center in Albuquerque to have it done as soon as possible.

WHY AN EMBOLUS CAN BE A SERIOUS PROBLEM
An embolus is a blood clot that travels through your bloodstream and lodges in an artery, either partially or completely blocking blood flow. The purpose of dialysis is to filter harmful wastes from your body and flush them out through a catheter in your arm. If your fistula has been blocked by an embolus, it will not be able to perform its vital functions properly—potentially resulting in serious health complications, such as inflammation of soft tissues or a sudden drop in blood pressure.
MANAGEMENT OF EMBOLUS IN NONFISTULATED SITES:
The management of embolus in nonfistulated sites depends on many factors, including needle size and flow rate used during hemodialysis. The fistula tract should be cleared with a low-pressure flush (10–20 psi) before withdrawing from nonfistulized sites to avoid air entrapment in adjacent areas. Large catheters or large needles may require a small tourniquet to isolate venous or arterial flow within a limb before withdrawing dialysate.
MAINTENANCE OF FISTULAS
There are 2 main types of fistulas: arteriovenous (AV) and venovenous. AV fistulas should be maintained at a flow rate higher than AV shunt fistulas because blood flows through them from one vein to another and not from a vein to an artery. Flow rates above 800 mL/min have been shown to improve hemodialysis outcomes, but can increase pain or bleeding if the flow is too high.
SUPPRESSION OF THE RESIDUAL ARTERY
Inadequate hemodialysis can occur if blood flow through a fistula is significantly below a certain threshold level. This may be due to thrombosis, or clots forming within the fistula (called arteriovenous (AV) fistulae). These clot formations can lead to a variety of complications including hemolysis and AV Fistula failure.
ANTIANGIOGENIC AGENTS IN ALBUQUERQUE DIALYSIS PATIENTS WITH FISTULAS
The best antiangiogenic agents are those that can be stented in a percutaneous procedure. This allows rapid cessation of fistula bleeding, treatment of thrombosis, and preservation of flow through the fistula. A stent may not be required at all, but if so it should be placed as soon as possible after bleeding ceases.
