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 ...
TIF is a late complication of a tracheotomy and is associated with prolonged endotracheal intubation, as a result of cuff over inflation or a poorly positioned tracheostomy tube. [1] [4] Over inflation of the cuff causes the tracheostomy tube to erode into the posterior aspect of the innominate artery leading to the formation of a fistula. [2]
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.
The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]
The complications are fewer than with other access methods. If a fistula has a very high blood flow and the vasculature that supplies the rest of the limb is poor, a steal syndrome can occur, where blood entering the limb is drawn into the fistula and returned to the general circulation without entering the limb's capillaries. This results in ...
They can provide venous access for up to one year. The patient may go home with a PICC. They avoid the complications of central line placement (e.g. pneumothorax, accidental arterial cannulation), and they are relatively easy to place under ultrasound guidance and cause less discomfort than central lines. [3]
The procedure was invented by doctors James Cimino and M. J. Brescia at the Bronx Veterans Administration Hospital in 1966. [6] Before the Cimino fistula was invented, access was through a Scribner shunt, which consisted of a Teflon tube with a needle at each end. Between treatments, the needles were left in place and the tube allowed blood ...
