ABSTRACT
Sneddon's syndrome (SS) is characterized by ischemic cerebrovascular episodes and livedo reticularis. It is more common in young women and can also be associated with valvulopathy, a history of spontaneous abortion, renal involvement and vascular dementia. We describe three cases of young women with this disease. The patients had repeated ischemic cerebral episodes, livedo reticularis and thrombocytopenia. CT and MRI showed strokes and cerebral atrophy. Autopsy in one of the patients revealed cerebral infarctions. Anticardiolipin antibodies were detected in two patients. Antiphospholipid antibodies may be found in some patients with ischemic cerebrovascular events and livedo reticularis. SS may thus be associated with antiphospholipid syndrome. We described three new cases of SS and discuss the pathophysiology of this disease.
RESUMO
A síndrome de Sneddon é caracterizada por episódios cerebrovasculares isquêmicos e livedo reticular, sendo mais comum em mulheres jovens, e pode também apresentar valvulopatia, história de aborto, envolvimento renal e demência vascular. Descrevemos três mulheres jovens com esta entidade. Os pacientes apresentavam história de ataques isquêmicos cerebrais, livedo reticular e trombocitopenia. Tomografia computadorizada e ressonância magnética de crânio mostraram infartos e atrofia cerebral nos pacientes estudados. A autópsia revelou em um dos pacientes presença de infartos cerebrais. Anticorpos anticardiolipina foram observados em duas pacientes. Há pacientes com eventos cerebrovasculares isquêmicos e livedo reticular nos quais anticorpos antifosfolípides são detectados. Então SS pode estar associada com a síndrome antifosfolípide, porém em alguns pacientes estes anticorpos não são detectados. Nós descrevemos três novos casos de SS e discutimos os mecanismos fisiopatológicos desta síndrome.
