85% of patients in hemodialysis suffering complications.

-The majority of complications due to narrowings in veins that dialysis is practiced
– If the problems persist, patients must be operated with urgency, unable to practice the hemodialysis, needed to keep it alive
– to deal with the complications, practiced a vein dilation, using multiple devices. Along with the most common, angioplasty, other procedures that are currently in phase of study and development, as the crioplastia, ball court, have presented the ‘ stents ’ farmacoactivos and techniques with stem cell
-thousand people of every million people require hemodialysistwo or three times a week to survive
– is necessary to continue emphasizing the need for donations of bodies to carry out kidney transplants ”
Bilbao, November 2010- Bilbao has become last Friday and Saturday in the Centre of study of the dialysis of the State. Thus the 5th course of vascular access for hemodialysis, organized by the Spanish Foundation of hemodialysis, pointed out that 85 percent of patients in hemodialysis suffering complications of narrowing or thrombosis of the veins that applies the treatment ”. This reality, referred to during the presentation of AgustÃn Azpiazu, vascular Interventional Radiologist of Vitoria-Gasteiz Txagorritxu Hospital, affects directly to a population estimated at a rate of a thousand people for every million inhabitants.
Patients to undergo hemodialysis, should be tapped to connect one of his veins to an artery, preferably in the arms, so that blood vessel possess an irrigation and sufficient pressure to successfully perform the treatment. The problem is ”, noted Azpiazu, in that in the vast majority of cases, to make the two necessary puncture so repeatedly – 2 or 3 times a week – the walls of the vessel begin a process of thrombosis or enclosure that can collapse the arterio-venous fistula ”.
The result of this process is not minor. If the Fistula is closed, the patient must be submitted to a new operation in a few days to prepare a new vessel which carry out again hemodialysis, because without it, he died ”.
New solutions to old and recurrent problem
Vascular Interventional Radiologist of Vitoria Txagorritxu hospital explained that the most common procedure is currently the angioplasty, which inserts a tiny catheter with a balloon inside the arterio-venous fistula (FAV) of the patient, widening the vessel and allowing the passage of blood through the ”.
However, Azpiazu filed with broad representation of physicians and nurses of all Spain that have gathered in this course, the latest global developments in this field. Thus, pointed out that crioplastia, already used successfully for other uses in the lower extremities, allows, through a closed circuit cooling with liquid nitrogen at – 10 ° C the arterio-venous fistula and inflate a ball that has been associated in this way ”. The use of cold due to a process of cell apoptosis cells die and do not reproduce, thus hindering the process of enclosure of the blood vessel ”.
The vascular radiologist continued reviewing other devices, ball court, a technology as well as opening the light of the blood vessel through a catheter with a balloon, increasing its effectiveness through small incisions made by tiny blades on the walls of the FAV ”. As he emphasized, is one of the devices more advanced now ”.
The expert also addressed the ‘ stent ’ farmacoactivos, preferably used in the coronary arteries and which could also be applied to arterio-venous fistulas. These devices as well as opening the walls of the fistula, release a drug that inhibits cell growth, largely contributing to the permanent opening of the glass ”.
Azpiazu has ended his presentation by emphasizing the need for one sufficient number of donations of organs, in order to respond in the best way possible to the existing demand for kidney transplants, only way to be able to dispense with renal replacement therapy for this group of patients.
V course on vascular access for hemodialysis has been held at the Euskalduna Palace in Bilbao on 26 and 27 November. The course is organised by the Spanish Foundation of dialysis, in collaboration with the Spanish society of dialysis and transplant (SEDYT), the Spanish society of nursing Nefrológica (SEDEN), the Northern society of Angiology and Vascular Surgery and the Academy of medical sciences of Bilbao.
