    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 neuroimaging features of patients with SDCVA from a multiethnic population. Sixty-six patients diagnosed with SDCVA were studied at two tertiary hospitals at São 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 neuroimaging data from patients with SDCVA allows a better understanding of the disease, leading to an earlier diagnosis and more appropriate treatment.

    Spontaneous artery dissection in a patient with Human Immunodeficiency Virus (HIV) infection
    (Academia Brasileira de Neurologia - ABNEURO, 2006-06-01) Felício, André Carvalho [UNIFESP]; Silva, Gisele Sampaio [UNIFESP]; Santos, William Adolfo Celso Dos [UNIFESP]; Pieri, Alexandre [UNIFESP]; Gabbai, Alberto Alain [UNIFESP]; Massaro, Ayrton Roberto [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    BACKGROUND: The relationship between human immunodeficiency virus infection and stroke may be attributed in some cases to an underlying vasculopathy such as in spontaneous cervical arteries dissections. CASE REPORT: We report the case of an HIV-infected patient who developed a Wallemberg's syndrome due to a vertebral artery dissection. Screening laboratory exams showed hyperhomocysteinemia and also high C-reactive protein plasma levels. CONCLUSIONS: This is the first case describing the association between arterial dissection (AD) and HIV-infection. We suggest that AD should also be remembered as a possible mechanism of ischemic stroke in HIV-infected patients.
