Name of medical device

Intravascular stent

Description

The intravascular stent is a metal tubular medical device that can be used in a variety of forms, sizes, and lengths.

When to use

Vascular stents are mainly used in the condition of vascular stenosis or vascular rupture and bleeding. They must be placed in the diseased vessels through the endovascular catheter.

Possible side effects

Contrast agent allergy, local wound bleeding, acute renal failure, acute pulmonary edema, arterial dissection, vasospasm, vascular rupture, stroke, and even death.

Postoperative care

• After the examination, the catheter is left at the blood vessel puncture site. Please avoid bending your thighs and take care not to pull it.
• If the stent can be removed after evaluation, the doctor will apply pressure to the wound site to stop bleeding. Lie flat for 24 hours after hemostasis, and pressurize the puncture site with a sandbag for 8 hours. Family members are asked to pick up the sand bag every hour, observe whether there is bleeding or abnormality at the puncture site, and then press the sand bag back to its original place. If using styptic cotton or other hemostatic devices, sandbag pressure and flat lying time can be shortened. Please consult relevant medical staff.
• As a contrast agent is administered during the operation, it is advisable to drink more liquid and increase urination to expel the contrast agent from the body.
• During the first 2 weeks after discharge, avoid applying heavy pressure to the puncture site, do not carry heavy stuff or do strenuous exercise.
• Please receive follow-up exam regularly at the outpatient clinic after discharge. If your physician prescribes anticoagulants, take them as directed.
• Prior to any future treatment, you must inform your physician that you have a stent implanted. For an MRI exam, tell your physician or MRI technician that you have a stent implanted. According to the regulations, you may not undergo an MRI exam until at least 8 weeks have passed after stent implantation.
