Fifty consecutive human autopsy specimens were studied to determine the suitability of the superficial temporal artery (STA) for use in microvascular anastomoses. Ten variations of the STA were found. The STA at the zygoma averaged 2.2 mm in outside diameter. The STA averaged 31.7 mm from the zygoma to its bifurcation, where the average outside diameter was 1.9 mm. Eight per cent of the specimens had no bifurcation, and 92% had at least one branch in a frontal or parietal distribution that was greater than or equal to 1 mm. A suitable frontal branch (i.e., greater than or equal to 1 mm in diameter and greater than or equal to 70 mm in length) was found in 90% of the specimens, and a suitable parietal branch was found in 71%. Six specimens (12%) had an additional branch, all of which were of suitable length and diameter. Eight per cent of the specimens lacked a vessel suitable for microvascular anastomosis.
A case of recurrent Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum) in a child is described with a summary of the clinical presentation and associated malformations, and a review of other cases reported in the literature. The histological examination and electron microscopic findings, with special reference to the cytological changes found during evaluation of the recurrence, are presented. Theories regarding the pathogenesis of Lhermitte-Duclos disease are reviewed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
