Use method of vascular fistulation improved stent used for hemodialysis

Abstract

The invention discloses a use method of a vascular fistulation improved stent used for hemodialysis. The use method comprises the following steps of disinfection, intravenous built-in stent implantation, blood vessel protection sleeve implantation, fixing, dialysis and stent maintenance. According to the use method of the improved stent, through artery-vein separation, blood shunted from arteriesto veins is reduced, the pressure of backflow vein blood vessels is reduced, and expansion of part of blood vessel sections is effectively prevented. After a vein is longitudinally cut open and the stent is put into the vein, a vein incision can be directly sealed due to the fact that a blood vessel protection sleeve is provided with a sprocket-shaped structure, and the vein incision can also be sealed through the protection sleeve after simple suturing; the surgical operation complexity of a doctor is reduced, and the surgical time is saved; by means of fixed puncture holes reserved in the two ends of the stent, a buttonhole puncture method and a blunt needle are combined for application, a puncture fistula is easy to form, damage of vascular puncture to blood vessels can be reduced, painof a patient can be relieved, and the vascular puncture difficulty of nurses is reduced.

Description

technical field [0001] The invention relates to a method for using a stent, in particular to a method for using a vascular leak-improved stent for hemodialysis. Background technique [0002] Angiostomy is the use of vascular surgery to artificially establish a short circuit between arteries and veins. There are mainly two methods: autologous angiostomy and artificial angiostomy. The main purpose is to arterialize the veins to ensure blood flow. The dialysis process has sufficient blood flow and the convenience of vascular puncture. However, the existing technical operations also cause various complications during treatment, such as thrombosis, steal syndrome, non-thrombotic stenosis, hemangioma, swollen hand syndrome, and high-output heart failure. In view of the above problems, we provide an improved hemodialysis angiostomy method and stent application technology, which not only maintains the advantages of the original technology, but also reduces damage to blood vessels, ...
