    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.

    Ectasia da artéria basilar e acidente vascular cerebral: aspectos clínicos de 21 casos
    (Academia Brasileira de Neurologia - ABNEURO, 1997-09-01) Oliveira, Roberto de Magalhães Carneiro de; Cardeal, Jose Osmar [UNIFESP]; Lima, José Geraldo De Camargo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Ectasia of the basilar artery (EB) occurs when its diameter is greater than normal along all or part of its course, and/or when it is abnormally tortuous. EB may cause cranial nerve dysfunction, ischemic stroke or subarachnoid hemorrhage, pseudotumor or hydrocephalus. We tried to describe cases of stroke associated with EB, analyze its frequency, clinical aspects, and the mechanisms involved in different forms of its presentation. We found 21 patients with stroke and EB. The association between EB and stroke was more prevalent in males over the age of fifty. Main symptoms were hemiparesia, cranial nerves dysfunction, and cerebellar ataxia. Cerebral infarcts associated with EB were due to different mechanisms: arterial thrombosis, artery-to-artery embolism, mass effect with angulation and obstruction of the vertebral and basilar branches.

    Ectasia da artéria basilar e acidente vascular cerebral: estudo por imagem em 21 casos
    (Academia Brasileira de Neurologia - ABNEURO, 1997-09-01) Oliveira, Roberto de Magalhães Carneiro de; Cardeal, Jose Osmar [UNIFESP]; Lima, José Geraldo de Camargo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Ectasia of the basilar artery (EB) may cause different clinical manifestations, and its analysis by imaging methods is fundamental. We tried to analyse radiological aspects in 21 patients with stroke and EB. In all of them, diagnosis could be done by computed tomography. However, magnetic resonance was the most complete diagnostic method for the evaluation of the relantionship between EB an surrounding structures.
