Things to Know About Stent Implantation
The non-surgical treatment method to open narrowed coronary arteries so as to extend blood flow to the guts is termed stent placement and/or balloon angioplasty. Narrowed or clogged blood vessels (coronary arteries) that carry clean blood to the guts may be opened with this method. The choice for the Balloon/Stent procedure may vary in line with the clinical condition of the patient.
Stent Implantation
In most cases, stent placement is performed together with the balloon angioplasty procedure. A stent may be a small metal mesh tube that acts as a skeleton to produce support within the arteria. A balloon catheter advanced over the guidewire is employed to position a stent within the narrowed artery. When the stent reaches the narrowed area, the balloon is inflated and therefore the stent expands in accordance with the diameter of the artery and attaches to the vessel wall. After the balloon is deflated, the stent remains permanently at the purpose where it had been placed. Within some weeks, the stent heals by being covered with normal vascular cells (endothelium). Angioplasty with a stent is typically recommended for patients with narrowing or occlusion of 1 or both coronary arteries. If there's a blockage in addition to two coronary arteries, artery bypass surgery could also be considered.
Why Is Stent Implantation Made?
The main purpose of the stents is to make sure that the fluid flow within the applied tissue continues without interruption. Accordingly, it's most typically employed in the clinic to reopen the narrowed blood vessels thanks to vascular plaques. The coronary vessels of the center may narrow with the event of plaque as a result of atherosclerosis, and also the heart tissue bereft of blood support could also be damaged over time, paving the way for an attack. Due to the stent, the plaques are removed and also the vascular patency is restored, and this patency is tried to be preserved by keeping the stent permanently.
Apart from this, stents also can be used for the subsequent purposes consistent with the appliance site:
- Ensuring normal vascular patency by removing abnormal enlargements called aneurysms within the vessels of organs, especially the brain,
- Prevention of recurrence by removing occlusive substances like stones within the bile ducts or tract tissues like ureters,
- Protection of the system by providing patency within the bronchi.
How is that the Stent Applied?
Patients mustn't eat 8 hours before the stent procedure. However, drugs that make bleeding control difficult, especially blood thinners, are discontinued before the operation. Within the near-operation period, patients are asked to not smoke and drink alcohol, to notify the doctor immediately in the presence of infections like colds, and to follow the doctor's instructions for treatment arrangements associated with other diseases.
The stenting procedure isn't a highly aggressive surgery and is performed under certain imaging techniques. Before the procedure, the key vascular structures within the groin are determined. The stent, which is wrapped around a deflated balloon, is placed within the appropriate position by being directed from the veins within the groin to the relevant vein of the guts. The stent is deployed by inflating the balloon, then the balloon is deflated and removed. After the procedure, the intervention area is sutured and a pressure dressing is applied and followed.
Similarly, in stents placed in extravascular structures, the stent is positioned within the right region with the assistance of catheters directed outside the body within the light of radiological imaging of the relevant region.
