The type of vascular access created for patients on hemodialysis is influenced by factors such as the expected time course of a patient's kidney failure and the condition of his or her vasculature. Patients may have multiple accesses, usually because an AV fistula or graft is maturing and a catheter is still being used. The creation of all ...
Cimino recognized that these fistulas did not cause the patients harm and were easy places to get repeated blood samples. He convinced surgeon Kenneth Appell to create some in patients with chronic kidney failure and the result was a complete success. Scribner shunts were quickly replaced with Cimino fistulas, and they remain the most effective ...
Vascular access steal syndrome is a syndrome caused by ischemia (not enough blood flow) resulting from a vascular access device (such as an arteriovenous fistula or synthetic vascular graft–AV fistula) that was installed to provide access for the inflow and outflow of blood during hemodialysis.
Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Kidney dialysis (from Greek διάλυσις, dialysis, 'dissolution'; from διά, dia, 'through', and λύσις, lysis, 'loosening or splitting') is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer ...
Kidney dialysis patients are among those most at risk from COVID-19, which is especially deadly among people with chronic illnesses. Dialysis clinics provide new path for delivery of stockpiled ...
A dialysis catheter is a catheter used for exchanging blood to and from a hemodialysis machine and a patient. The dialysis catheter contains two lumens : venous and arterial . Although both lumens are in the vein, the "arterial" lumen, like natural arteries, carries blood away from the heart, while the "venous" lumen returns blood towards the ...
As US Surgeon General Dr. Vivek Murthy nears the end of his second term as the nation’s doctor, a final diagnosis of his patient suggests that a great deficiency of connectivity has led to a ...
Revision Using Distal Inflow (RUDI) is a surgical treatment for Dialysis-associated Steal Syndrome. RUDI was first proposed by David J. Minion and colleagues in 2005. In the procedure, the fistula is ligated at a location slightly proximal to the anastomosis. A bypass to the venous outflow is then created from a distal arterial source.
