Cervical artery dissection - review
ln recent years carotid and vertebral artery dissections
have been diagnosed more frequently, probably because
new imaging techniques are more reliable and they
are certainly less invasive. The cause of cervical artery
dissections is largely unexplained but probably involves a
combination of genetic and environmental factors such as
trauma or infection.
Most authors recommend intravenous heparin or low
molecular weight heparin followed by oral warfarin to
maintain INR between 2-3 for 3-6 months. If the artery has
healed after 3-6 months of anti-coagulation all treatment
can be stopped but if there is a remaining stenosis the
patient can be put on aspirin 75-100 mg a day. The long-
term prognosis of cervical artery dissection is favourable in
the majority of patients. New dissections are uncommon.
