Local Symptoms and Recanalization in Spontaneous Carotid Artery Dissection

To the Editor:We congratulate Nedeltchev and coworkers for their meritorious report1 on recanalization of spontaneous internal carotid artery dissection. The strengths of this work are a fairly large patient population compared with most previous reports and the repeated ultrasound examinations of the vasculature at 1, 3, 6, and 12 months.
