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 ...
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.
An arteriovenous graft serving as a fistula for hemodialysis access. A vascular bypass is often created to serve as an access point to the circulatory system for hemodialysis. Such a bypass is referred to as an arteriovenous fistula if it directly connects a vein to an artery without using synthetic material. [citation needed]
Ischemic monomelic neuropathy (IMN) is an uncommon vascular access complication in hemodialysis patients that manifests as multiple mononeuropathies without clinical ischemia. [1] Ischemic monomelic neuropathy is most likely to affect patients who have had brachiocephalic vascular grafts, and it is characterized by symptoms of acute pain ...
Complication of catheter insertion rarely causes arteriovenous fistula. It is usually caused by brachial artery puncture because brachial artery is located between two brachial veins. [6] Surgically created Cimino fistula is used as a vascular access for hemodialysis. Blood must be aspirated from the body of the patient, and since arteries are ...
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 ...
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 ...
Hemodialysis, also spelled haemodialysis, or simply dialysis, is a process of filtering the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure.
