Experience of mechanical thrombectomy for paediatric arterial ischaemic stroke.

Background: Paediatric arterial ischaemic stroke (AIS) is an important cause of acute neurological symptoms in children, it causes significant morbidity and is one of the top ten causes of childhood deaths. Consensus papers have suggested guidelines for the management of AIS in childhood, although none recommend thrombectomy. Despite this, children within our institution have undergone mechanical thrombectomy for large vessel occlusion.

A comparative study of alpha-dystroglycan glycosylation in dystroglycanopathies suggests that the hypoglycosylation of alpha-dystroglycan does not consistently correlate with clinical severity.

Hypoglycosylation of alpha-dystroglycan underpins a subgroup of muscular dystrophies ranging from congenital onset of weakness, severe brain malformations and death in the perinatal period to mild weakness in adulthood without brain involvement. Mutations in six genes have been identified in a proportion of patients. POMT1, POMT2 and POMGnT1 encode for glycosyltransferases involved in the mannosylation of alpha-dystroglycan but the function of fukutin, FKRP and LARGE is less clear.
