El PaÃs Vasco pioneered the use of veins frozen as vascular access for hemodialysis.
La Fundación Española of dialysis, in collaboration with the Spanish society of dialysis and transplant (SEDYT), organized the 6th course of vascular access for hemodialysis in the Palacio Euskalduna of Bilbao.
– two years in Galdakao Hospital uses frozen veins from varicose vein operations
-the course objective is reviewing current and techniques for the future, in order to improve the safety and efficacy of vascular access and improve the quality of life of patients
-hemodialysis is an extracorporeal blood purification technique began in Spain in 1957
-the number of patients with kidney disease that require hemodialysis, grows every year and is situated in lathe to 1,000 patients for every million inhabitants
-vascular access is now the leading cause of admission of patients in hemodialysis
Spain, 2011-December hemodialysis is a technique of extracorporeal treatment of blood of patients with kidney failure. This means that they must connect to a machine that will extract the blood and her depurará. To perform this process it is necessary to create an access to the veins of the patient, through surgical intervention, where draw her blood to purify her and then re-enter her. It is what we call vascular access.
Currently, at the beginning of the stage of dialysis patient might vascular path three possibilities: AV Fistula, the prosthesis and the catheter. They are indispensable in hemodialysis and often lead to problems for patients, due to the repetition of the puncture and wear of the veins (a person in hemodialysis often do two or three sessions per week). As pointed out by using the Dr. Ãngel beard of the Hospital Galdako-it and co-director of the course the punctures in the same area cause aneurysms that can estenosarse and trombosarse, that is why we recommend wherever possible vary along the vein puncture points to minimize it ”.
The main problem of hemodialysis is the narrowing of the veins that dialysis is practiced. The Dr. Julen Ocharan-Corcuera in the Hospital Txagorritxu, President of the SEDYT and co-director of the course, remember that when closes a vein, the patient must undergo a new operation in a few days to prepare a new vessel which carried out again, hemodialysis because without it, he died ”.
On existing vascular access systems it should be noted, as the experts say that venous catheters have a lower survival rate, the efficiency to administer the dose of hemodialysis is lower and they are at high risk of infection.
With regard to the fistula, Dr. Beard as Dr. Ocharan-Corcuera agree that should be considered the first choice for having morbidity and low complication rate. It has disadvantages that the time required for maturation is long, which sometimes does not provide the necessary flow, and which is not always possible, for example, with diabetic patients, with severe atherosclerosis in obese and in people with small and deep veins ”.
When an internal vein arteriovenous fistula cannot be achieved, is carried out through arteriovenous-venous connection the implant of a tubular graft of synthetic material. It is a more expensive solution economically and with more morbidity for the patient. However, according to experts, graft is advantage to the largest area, an easier channel and a short period of maturation ”.
Since a couple of years, in the Basque country, and so hospitals pioneered all Spain have begun to use a new technique as vascular access. It’s using learned operations of varicose veins. These veins are measured, are measured (identifies blood group) and freeze. When we need them, use them for hemodialysis. Instead of putting prostheses, use as a vascular access these veins ”. According to Dr. Ãngel beard this is a technique that works better and less seamless ”.
The 6th course on vascular access, met in Bilbao past 25 and 26 November, experts in hemodialysis (Vascular Surgeons, angioradiólogos, Nephrologists and nephrology nursing) discussed the most common problems of vascular access and how to work together to improve them, so that the patient has a higher quality of life and greater security.
