Revision Using Distal Inflow
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. In a review of a three studies on the efficacy of the technique, RUDI was shown to provide good patency (80%-100%) and 100% symptom resolution.{{cite journal , vauthors= Ahmed M, Peden, E , title = Dialysis-associated steal syndrome (DASS) , journal = J Vasc Access , volume = 18 , pages = 68-73 , year = 2017 , doi = 10.5301/jva.5000684 References Vascular surgery ...

Vascular Access Steal Syndrome
In nephrology, 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. Signs * Pallor * Diminished pulses (distal to the fistula) * Necrosis * Decreased wrist-brachial artery, brachial index (ratio of blood pressure measured in the wrist and the blood pressure measured in the upper arm), especially if below 0.6 Symptoms * Pain and nociception, Pain distal to the fistula. Symptoms are graded by their severity: * Grade 0: No symptoms of steal * Grade 1: Mild - cool extremity, improvement in hand pulse with access occlusion * Grade 2: Moderate - Ischemic symptoms during dialysis * Grade 3: Severe - Ischemic hand pain outside of dialysis; Ulcers or gangrene of the fingers Diagnosis * History and physical exam - relief of symptoms with compression ...

Fistula
A fistula (plural: fistulas or fistulae ; from Latin ''fistula'', "tube, pipe") in anatomy is an abnormal connection between two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs. Types of fistula can be described by their location. Anal fistulas connect between the anal canal and the perianal skin. Anovaginal or rectovaginal fistulas occur when a hole develops between the anus or rectum and the vagina. Colovaginal fistulas occur between the colon and the vagina. Urinary tract fistulas are abnormal openings within the urinary tract or an abnormal connection between the urinary tract and another organ such as between the bladder and the uterus in a vesicouterine fistula, between the bladder and the vagina in a vesicovaginal fistula, and between the urethra and the vagina in urethrovaginal fistula. When occurring between two parts of the intestine, it is known as an enteroenteral fistula, between the sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
