CAROTID (AND VERTEBRAL) DISSECTIONS: QUICK HITS


first consult call to Neurologists (less commonly Vascular Surgeons)


–Vascular imaging is a must, but CTA is more sensitive than MRA.  


–To catch on MRI, specific sequences are required so check with your Neurologist/Radiologist to figure out which.  


Dissections that extend intracranially have a high incidence of forming SAH, especially when heparin is started, thus making heparin have higher mortality than anti-platelet drugs.  


Extracranial dissections are usually treated with antiplatelet drugs and anticoagulation
