Background
The arteriovenous fistula is characterized in that a vein of a patient is sutured to an artery, so that the blood flow in the vein is increased, and the flow requirement of hemodialysis is met; during dialysis, two needles can be punctured at the internal fistula, one needle can lead blood out of the body, and the other needle can return the purified blood into the body.
According to KD0QI established by the national kidney foundation of the 2015 edition and the consensus of vascular access experts for hemodialysis in china (2 nd edition), the current assessment and monitoring method comprises: (1) physical inspection; (2) pressure monitoring: including static and dynamic pressure monitoring; (3) monitoring the recirculation; (4) monitoring the flow of the access; (5) imaging diagnosis and evaluation: doppler ultrasound, magnetic resonance angiography, intravascular ultrasound, digital Subtraction Angiography (DSA), helical CT angiography, CO2 angiography, and the like. In the above evaluation and monitoring method, the physical examination is subjective examination, and the individual factors of the examiner have a large influence on the result and cannot quantify and record the result; pressure monitoring, whether dynamic or static, can interfere with the normal hemodialysis process, possibly leading to the occurrence of adverse dialysis reactions, so that conventional monitoring is not carried out in clinical work; the recirculation monitoring, the passage flow monitoring and the imaging diagnosis and evaluation all need the detection of professional personnel, special reagents and equipment.
In addition, vascular embolism or stenosis is the primary reason for the loss of the access function of the arteriovenous internal fistula, and various reasons for vascular embolism or stenosis exist, wherein the nursing factors comprise improper puncture, hematoma formed by the arteriovenous internal fistula and the like, and the fistula is pressed.
