Molecular Approach to Turkish Pediatric Stroke Patients.

to either vascular occlusion or rupture of vessels with subsequent bleeding and neurologic deficits. Stroke secondary to vascular occlusion may occur in the venous drainage of the brain, sinovenous thrombosis (SVT) or in the arterial supply to the brain, arterial ischemic stroke (AIS). Parenchymal damage or infarction of the brain occurs commonly as a squeal of AIS and less commonly of SVT[1]. Stroke is a rare event in childhood. Several figures estimated the incidence at 0.6-1.2 per 100.000 children per year[1]. Figures from Turkey, are hospital based studies indicating that one out of 170 hospitalized pediatric patient experience thrombosis; of which stroke compromises almost one third of the total thrombotic patients[2,3].
