Spontaneous carotid and vertebral arteries dissection in a multiethnic population

Spontaneous dissection of the carotid and vertebral arteries (SDCVA) is considered a rare cause of stroke, particularly in countries with multiethnic population. The objective was to evaluate the clinical and neuroirnaging features of patients with SDCVA from a multiethnic population. Sixty-six patients diagnosed with SDCVA were studied at two tertiary hospitals at Sao Paulo. An initial questionnaire was completed and patients were followed prospectively. Among the patients studied, 82% were caucasian, 53% were male and the average age was 41.7 years old. The most frequent cardiovascular risk factors found were systemic hypertension and tobacco use. Other aspects evaluated were history of previous migraine, initial treatment and prognosis. in conclusion, although the population studied was multhiethnic, there was a marked predominance of caucasians. The analysis of clinical and neuroirnaging data from patients with SDCVA allows a better understanding of the disease, leading to an earlier diagnosis and more appropriate treatment.
