Cardiologists of the Military Clinical Hospital in Wrocław for the first time implanted a state-of-the-art stent in the patient, which will be completely absorbed within two years.
The stents used in a military hospital begin to decompose just a few months after the surgery. They completely dissolve after two years, when the vessel wall is already rebuilt.
As the head of the Hemodynamics Laboratory of the Center for Heart Diseases at the 4th Military Teaching Hospital in Wrocław, prof. Krzysztof Reczuch, who performed the procedure, is the dream of biotechnologists and doctors that the vascular prosthesis should be present in the body only as long as there is a possibility of recurrence of the artery narrowing.
Our hospital is the first one in Wrocław to use soluble stents. Although they are two or three times more expensive than the classic ones, we intend to operate on over a hundred patients this year. Reczuch said.
Soluble stents are especially recommended in the case of young people, actively practicing sports, diabetics and those for whom surgery is being considered for some time.
Currently, the National Health Fund only covers the implantation of insoluble stents. The remaining cost is covered by the hospital from special funds allocated for this purpose. We are committed to developing the most modern methods of treatment in cardiovascular diseases. Considering the health of patients, it always pays off. We predict that approximately 7-70 percent of of implanted stents, they will be soluble stents – added Reczuch.
About 100 jobs are carried out annually in Poland. stenting procedures in patients with coronary stenosis and at risk of having a heart attack. The ones that have been used so far have been a metal scaffold to prevent the blood vessels from narrowing again.
The use of a soluble stent in the treatment of ischemic heart diseases is the fourth revolution in interventional cardiology. The first was the introduction in the late 70s of the method of widening the strictures in the coronary arteries using a balloon catheter inserted into the coronary artery through a puncture of the femoral artery. Thanks to this, many patients could avoid the so-called implantation surgery. bypasses, which is associated with the opening of the chest and the risk of complications.
The second revolution was the introduction of stents in the 80s, i.e. metal scaffolding mounted on balloons. After balloon dilatation, the metal scaffold remained permanently in the previously narrowed artery segment. Their use made it possible to significantly reduce the risk of sudden and dangerous closure of the vessel, which sometimes occurred after expanding with the balloon itself.
Unfortunately, in some patients, after metal stent implantation, the narrowing of the arteries returned. Scientists found a way to do this and at the beginning of the 70st century they carried out the so-called third revolution. It consisted in coating metal stents with substances inhibiting the growth of the vessel wall. As a result, the frequency of restenosis recurrence was reduced by approximately XNUMX%. (PAP)
