Stenosis means narrowing or
contraction of an abnormal channel or hole. Case of stenosis in the carotid
arteries (heart blood vessels) and intracranial blood vessels (in the brain)
can lead to a stroke. In patients who show symptoms of stroke (symptomatic),
the action taken to eliminate the so-called stenosis stenting. Carotid stenting
is a non-surgical but invasive procedure that aims to dilate blood vessels
carotid stenosis by using a device called a stent plus supporting equipment
(balloons and protective mechanisms). Stenting can provide high gain if the
degree of stenosis of more than 70% and also in some cases the degree of
stenosis 50-69%. If the patient had no symptoms (asymptomatic), minimizing the
risk of stroke and stenting can be performed in patients with a degree of
stenosis of more than 60%
Indications and Contraindications
Carotid stenting in large enough
quantities was first performed in 1994 by Dr. Jay Yadav did in patients after
carotid endarterectomy (surgery lift blockage in the blood vessels) who
experienced restenosis. Indications stenting is to address the magnitude of
lesion stenosis of more than 70% (in the asymptomatic) or are still about
50-69% (in patients with symptomatic). The advantage much more when stenting is
performed at the first large lesions (> 70%). Carotid stenting should not be
performed when plaque is difficult to reach due to the blood vessels that are
too complicated (winding serpentine) and occurs classification (liming) great
arch vessels around the heart. If there is a thrombus (occlusion) is shaped
like a pendulum on the side of the plaque, then stenting is not recommended. In
addition, carotid stenting is also not allowed for patients who are resistant
to antiplatelet drugs (anti-clotting), patients with kidney failure and end
stage of being, as well as patients who have a history of stroke complete
within three weeks.
Complications
Carotid stenting can lead to
complications, including:
- Stroke or death
- Nerve palsy brain
- Bruised groin area, around the entry of the tool used
Plaque in the carotid arteries and intracranial
vessels accounted for about 20-30% of the stroke. In an effort to prevent
recurrent ischemic stroke by removing plaque before, then carotid stenting is
an acceptable way. Carotid artery stenting has several advantages in preventing
recurrent ischemic stroke, for example, can be performed in high-risk patients,
the rate of complications after the action is relatively small, post-stroke
mortality and a low action, length of stay in hospital relatively short (4-5
days if not no complications) so that the total cost of patients are also more
efficient and shorter recovery time.
