Presenting characteristics in 200 carotid dissections with and without ischemic events*

CharacteristicsCarotid dissection, n (%)
With ischemia (n = 145)Without ischemia (n = 55)
* Carotid dissections occurred in 181 patients with a mean age ± SD of 45 ± 11 years. For each carotid dissection, age, sex, and vascular risk factors of the corresponding patient are given.
p < 0.05 that the difference between carotid dissections with and without ischemic events is significant (Wilcoxon signed rank test).
‡ Carotid dissections with and without ischemic events occurred in 32 and 12 women aged 18 to 44 years, respectively.
§ Catheter angiography was performed in 60 carotid dissections with and 17 carotid dissections without ischemic events.
