Stenting is a non-surgical procedure in which a mesh tube (stent) is inserted into a narrowed blood vessel to restore blood flow.
The purpose of stenting is to open clogged or narrowed arteries or veins, improving blood flow and preventing further damage.
Stenting can be performed to treat the following conditions:
- Heart attack
- Angina pectoris (chest pain)
- Peripheral artery disease
- Narrowing of the renal arteries
- Atherosclerosis (blockage of arteries)
Stenting is usually performed under local anesthesia. The doctor inserts a catheter through the femoral or radial artery and guides it to the affected area.
When the catheter reaches a narrowed blood vessel, a balloon is inflated to dilate the vessel. Then a stent is inserted into the artery and expanded with another balloon. Stents are usually made of metal or polymer.
After stenting, patients are usually monitored for several hours. They will need bed rest and may be prescribed medications to prevent blood clots.
As with any medical procedure, there are some risks associated with stenting, such as:
- The bleeding
- Infection
- Damage to a blood vessel
- Allergic reactions
Stenting is usually a very successful procedure to restore blood flow and reduce symptoms. However, the long-term results depend on the patient's condition and the cause of the narrowing.
Depending on the specific situation, alternative treatments for narrowing of blood vessels may be available, such as:
- Medical treatment
- Angioplasty
- Surgery
The decision on which treatment option is most appropriate is made jointly by the doctor and the patient, based on the individual condition of the patient.
