Abstract
Summary and Conclusion
Extracranial carotid stenosis is a major cause of stroke. It has
been estimated that carotid artery disease is responsible for 20% to 30%
of stroke.
The 3-year risk of ipsilateral ischemic stroke is 16.8% for
patients with severe (70-99%>) stenosis in patients treated medically.
The well-established indications of CAS as a first therapeutic
option for a carotid revascularization are the following: recurrent
stenosis after CEA, radiation-induced carotid stenosis, anatomical
features (high carotid bifurcation near the skull base), tandem lesions
(proximal common carotid artery stenosis or distal stenosis in the
carotid siphon associated with the carotid bifurcation stenosis).
Compared with CEA, CAS has the advantage that it can be
done with the patient under mild sedation, requires no incision and thus
avoids the risk of cranial nerve palsy, and has fewer cardiovascular
complications. For its acceptance as a valid alternative to CEA, CAS
must fulfill the same criteria of safety, effectiveness and durability.
patients receive a dual antiplatelet regimen consisting of aspirin
(150mg daily) and clopidogrel (75mg daily). This treatment is started at
least 5 days before the stenting.
The procedure is performed under local anesthesia in an
angiography suite with biplane digital subtraction and road-mapping
