WHAT IS A STENT?
OPENING VESSEL OBSTRUCTION WITH BALLOON AND STENT
STENT OCCLUSION RISKS
I gathered all the developments and details about the stent in a single video in recent years. You can watch this video if you want. In this video, I drew attention to both the development of stents and the risks of occlusion. You can find answers to all your questions.
WHAT IS A STENT? AND RISKS OF Clogging
Angiography is performed on the patient under conditions necessary for occlusion in the heart vessels. This examination is the most appropriate option for diagnosing vascular occlusion. We have reviewed more detailed information for angiography on another page. If you want, you can access the video with the link below.
The number of occluded vessels and the degree of stenosis are determined by angiography. Ideally, if the patient is a multi-vessel patient, it is discussed at the council with Cardiovascular Surgery. STRICTURES ARE TAKEN WITH COMPLAINTS AND THE PATIENT’S CONDITION. A score is obtained from angiography with the Syntax scoring system. This score is also effective in the decision of surgery or stent.
If there is no multi-vessel occlusion in the angiography, the same session is performed without going to the council or balloon and stent operation is planned in another session.
WHAT IS A STENT?
The placement of a stent in the artery expanded with a balloon in the opening of the heart vessels has opened a new era in the treatment. Openable, stretchable stents, known as metal cages, expand the vascular occlusion from the inside.
STENT PROCESS:
WHAT IS A BARE STENT?
The first stents are known as ‘bare stents’. Technology has developed better stents, as vascular stenosis is often seen in the first experience.
WHAT IS A MEDICINE-COATED STENT?
Different drugs were placed on the bare stents, and “Medicated Stent” was made. The aim is to prevent the cells called endothelium forming the inner wall of the vessel from reacting against the metal. These cells enlarge and cause stenosis in the stented vessel.
Stents used to open stenosis in coronary vessels can be coated with drugs today. These stents, which contain special drugs that prevent re-narrowing of the coronary vessels, are called medicated stents. It is desired to prevent the formation of stenosis again in drug-coated stents. Although the bare stent fell behind in the comparison of the medicated stent to the bare stent, it has been claimed in recent publications that the results are not that bad.
WHAT IS A DISPOSABLE STENT?
Although dissolving stents have been developed in recent years, their use has decreased due to the formation of clots in the vein in the first studies. Various drugs have been introduced in recent years.
Technological developments in recent years have provided significant improvements in keeping the stents open for a longer period of time. In general, it can give more positive results in people with low level of vascular occlusion.
