Generalities

Carotid angioplasty is a treatment for carotid artery disease – a procedure performed on carotid arteries when they become clogged or narrowed by an atherosclerotic plaque. The procedure involves the placement of an antiembolic protection filter past the narrowing, followed by the placement of a nitinol-stent at the level of the narrowing. The stent maintains the artery open and prevents it from narrowing again. Carotid angioplasty is an alternative to open surgery, being used when the traditional surgical procedures are not feasible or pose a high risk.

Indications

• critical stenoses (>70%) of the carotid artery.

• the patient has suffered a stroke or a transient ischemic attack.

• the endarterectomy (the traditional surgical procedure) poses high risks for the patient.

• the stenosis is difficult to access by endarterectomy.

Carotid angioplasty is performed in the catheterization laboratories of our ARES centres in sterile conditions, under local anesthesia.

During the intervention the patient is conscious for the whole duration of the procedure and can speak with the doctor at any time, being permanently connected to heart monitoring machines.

The interventional cardiologist choses the type of vascular access, the most indicated in this case being the femoral artery access, then under local anesthesia he punctures the artery.

After a small puncture has been made, the doctor introduces a tube in the artery (the sheath), through which a series of guides and catheters will be subsequently introduced (narrow tubes), by which he advances under radioscopic guidance to the origin of the carotid artery.

Using these catheters, the doctor injects the iodine contrast agent, which opacifies the carotid arteries and by x-ray exposure, this way observing the blood flow and potential narrowings of the arteries.

If stenoses are found, a thin wire guide is passes through these, an antiembolic protection filter is placed in order to protect the brain (by trapping bits of plaque that may detach from the artery walls), then an auto expandable Nitinol stent is passed through the stenosis, which is placed at this level.

After the procedure, the cerebral blood flow is restored, thus eliminating the risk of stroke. The stent keeps the artery open and diminishes the risk of re narrowing of the artery.

Carotid artery angioplasty using an antiembolic filter with the placement of a Nitinol stent may be a very good alternative to traditional surgical procedures when the latter are not feasible or pose a high risk.

Is it painful?

No. The whole procedure is carried out under local anesthesia, the patient being conscious during the whole duration of the procedure.

How long does it take?

Usually the duration of the procedure is between 30 minutes-1 hour. The patient is allowed to drink and eat in the following hours.

Risks

Stroke – During the intervention blood clots may form and detach, which may get to the brain. The use of anti embolic filter and anticoagulants reduces this risk.

Allergy to contrast agents or other administered medication.

Hematoma at the puncture site.

Before procedure

55
The following blood tests need to be taken: hemogram, renal function tests (blood urea nitrogen – BUN, creatinine), coagulation tests.

The following investigations need to be made before the procedure: a recent electrocardiogram and an echocardiogram.

It is recommended not to eat/drink before the procedure, especially if the intervention is programmed in the morning.

The doctor must be informed about the current medical treatment before the intervention is programmed, as certain medication may need to be stopped before the procedure.

After procedure

Drink at least 2 liters of water per day in the following days in order to eliminate the contrast agent from the bloodstream.

Twenty-four hours after the procedure the vascular puncture site will be inspected to exclude any potential local complications.

An ECG is made

Sometimes, renal blood tests are taken (creatinine, blood urea nitrogen)
